Where is the valve for the VAZ 2115 stove located

The appearance of puddles of coolant in the car’s interior makes the owner wonder where the valve for the VAZ-2115 heater is located. In the vast majority of cases, this unpleasant symptom occurs precisely because of the leakage of this part. To replace a faucet, it is absolutely not necessary to go to a car service center - this procedure is quite simple and does not require any special knowledge or skills.

The heater valve in car 2115 is located at the bottom of the dashboard. You can reach it from the passenger seat. At the same time, to replace a part, you do not have to disassemble half of the machine, since access to it is almost completely open.

What is needed to replace the heater valve on a VAZ-2115 car

If a faucet is leaking, it must be replaced as soon as possible. Otherwise, the coolant can seriously flood the entire cabin. In such a situation, you will not only need to make repairs, but also spend quite a lot of time cleaning the car.

What is needed to replace the stove faucet? You only need a few tools and supplies:

set of socket and socket wrenches;
Screwdriver Set;
new part. It is best to choose modern ceramic taps, which are equipped with all the necessary sealing elements;
WD-40 liquid;

flashlight and gloves.

Replacing the VAZ 2115, 2116, 2113 stove faucet yourself is quite economically feasible. In official car repair shops, as of November 11, 2022, the price of work is on average 2 thousand rubles (excluding the cost of the part itself), in small workshops - about 1.5 thousand rubles. The work is not complicated, any car owner with his hands can handle it, but first you need to study the steps of how to replace the heater faucet. At the same time, the car owner will be able to independently determine the state of the system as a whole.

Work order

To replace the heater tap of VAZ 2114, 2113 and 2115, the car must be installed on a site convenient for work (preferably indoors). Repair algorithm:

Drain the coolant. This must be done on a cold engine. Old antifreeze is drained into the container through a plug located in the front of the car at the bottom of the crankcase.

For the convenience of work and its feasibility, we recommend moving the front passenger seat as far as possible, which will allow you to dismantle the shelf from below the dashboard (under the glove compartment). After removing the cover, the trim fasteners will be accessible. Unscrew the 5 screws of the lining and gain access to the pipe and the damaged old part. First loosen slightly and then remove the metal ties

Dismantling the pipes must be done carefully; it is advisable to lay old rags on the floor, which will absorb the remaining volumes of spilled antifreeze. After removing the pipes, unscrew the 2 nuts on the studs with a wrench. The faucet is now fully accessible

All that remains is to disconnect the cable that controls the damper and remove the old part.

Next, the elements are installed in the reverse order: first the panels, then the shelves. Don't forget to tighten the drain plug as well. Remove air from the heating system, unscrew the plug from the expansion tank of the engine intake manifold, disconnect the pipe, and fill in new antifreeze. The amount of liquid is determined by its flow. Fill the required volume of antifreeze and immediately connect the pipe.

You can also watch the replacement of the VAZ 2114 faucet in the video:

The process of replacing the stove valve on a VAZ-2115

First, completely drain the antifreeze into a previously prepared container to avoid leaks during the process of dismantling a leaky faucet. After completing this procedure, the following steps will be required:

loosen the clamps securing the pipes that connect the engine to the heater tap;
We clean the pipes using a metal brush and treat them with WD-40 liquid. This simple step will allow you to unscrew the old part without any problems;
unscrew the nuts that secure the faucet. To do this you need to use a key of 10;
We move into the car interior and, slightly pulling the part towards ourselves, remove the special spring retainer;
disconnect the valve from the control cable and remove it;
We connect the cable to the new part, install the spring clamp in place and screw the tap to the pipes.

Assembly is carried out in reverse order. When connecting a new faucet, be sure to use silicone sealant that is resistant to coolant, and also screw the drain plug into place. At the last stage, fill in antifreeze and check the operation of the system.

Stages of self-repair

What to do if the fan on the VAZ 2114 (2115,2113) does not work?

After watching the video on replacing the heater valve on a VAZ 2115, you can familiarize yourself with all the stages of work and begin to carry them out, following the following instructions:

The car is placed indoors, and with a cold engine, the coolant is drained through a special technical plug into a container provided for this purpose. The drain plug is located at the bottom of the crankcase housing on the front side of the machine. The front passenger seat is moved back to the maximum possible distance, then the shelf in the lower part of the dashboard, located under the glove compartment, is dismantled, which will provide access to the fastening of the side decorative trim of the lower part of the center console. By unscrewing the five screws securing the side trim, we gain access to the heating system pipes and to the faucet itself

Having loosened the clamps of the pipes, we proceed to carefully remove them, placing an old rag on the floor, on which the remaining antifreeze may spill. Important! Keep in mind that the seats on the heater radiator are plastic, and when exposed to high temperatures, the pipes may sour a little on them, so their dismantling must be carried out very carefully, otherwise you can break the radiator housing with excessive efforts.

From the engine compartment of the car, we remove the two coolant supply pipes on the heater tap, unscrew, using a 10 mm wrench, the two fastening nuts on its studs, after which we dismantle the old part from the interior, having previously disconnected the damper control cable. A new faucet is installed on the seat, we tighten the fastening nuts, and we treat the seats of the cooling system pipes with sealant, put them on carefully and tighten them with metal ties. We clean the seats on the heater radiator, treat them with sealant, as well as on the faucet itself, install new pipes for supplying antifreeze to the car's heating system, and then tighten the clamps on them. We reinstall the decorative side panel and the additional shelf under the glove compartment, tighten the engine cooling fluid drain plug, and then proceed to remove air from the system. We remove the plug from the expansion tank on the engine intake manifold, disconnect the antifreeze supply pipe and pour new liquid into the cooling system until it begins to flow out of both the manifold and the pipe, which we immediately reattach.

At this point, the do-it-yourself work on replacing the heater valve on a VAZ 2115 is completed, we start the car’s engine, carefully inspect the tightness of the cooling system, check the heat supply to the cabin and the functionality of the damper for switching between summer and winter modes, and if no problems are found, the vehicle can be started to operate . Also watch the video of installing a heater valve on a VAZ 2115 (similar work is carried out on models 2113, 2114):

How to choose the right stove tap

Finally, we would like to give some useful recommendations on choosing a heater tap for your car. The modern market offers several varieties of these devices:

The simplest option is a crane installed at the car manufacturer. It is built on a membrane element made of rubber, which often cannot withstand elevated temperatures and “sticks.” The solution to this problem is to replace the product. This is why it is better not to buy factory taps;
a ball valve, which will cost much more than a membrane valve, but will also last much longer;
ceramic device. The best option, which is deservedly considered the most reliable and durable. To make the body of such a faucet, a metal or polymer material that is resistant to overheating is used, and a pair of ceramic plates is used as a locking element.

Which faucet to choose for the VAZ-2115 stove? We recommend not saving on purchasing this part and choosing the most durable option. This will avoid frequent replacement and save a very decent amount of money.

Tips for purchasing and replacing pipes on a VAZ2115

As with any car, a moment arises when it becomes necessary to replace the pipes of the ventilation and heating system of the car interior. Malfunction occurs for various reasons. Pipes get cracked due to frequent temperature changes. Sometimes the ingress of oils and gasoline also leads to malfunction. Usually cracks and holes form in the pipes under the fastening clamps. If the pipes are of poor quality, a sharp increase in pressure in the cooling system (ICE) of the car engine also leads to malfunction of the pipes.

Saving tip

There is a need to replace the pipes with new ones. You should not spend money on new pipes manufactured specifically for the cooling and ventilation system of the VAZ2115. In a year they will crack and tear. It is better to buy a heater hose from a gazelle car with a diameter of 16mm. A 3 meter long hose will be sufficient. According to the outer diameter of the hose, clamps are purchased for mounting on fittings.

To replace faulty pipes, the machine is placed on an overpass, in an inspection hole. The car engine must cool down for at least an hour.

Cooling system design

When the engine is running, a lot of heat is generated for removal, which is used by the car’s cooling system, consisting of the following components:

1 - Heater radiator.
2, 3 - Outlet, underwater pipes of the heater.
4 - Pump hose.
5 - Pipe coming from the expansion tank.
6, 12 - Steam removal hoses.
7 - Tank cover.
8 — Expansion tank.
9 - Thermostat.
10, 19 - Outlet pipes.
11, 13 - Supply pipes.
14 - Cooling radiator.
15 — Radiator drain plug.
16 — Radiator blower fan.
17 - Pump

You need to drain the coolant from the system. Open the expansion tank cap. Remove the sides of the instrument panel in the cockpit. Open the liquid supply valve to the stove radiator. Drain the coolant into a 10-liter container by loosening the clamp on the liquid supply to the stove radiator and disconnecting the pipe itself. In this case, you need to be careful not to let the coolant get into your eyes. Direct the end of the pipe into the container, since the liquid from the container, after replacing the pipes, will need to be poured back into the cooling system. For ease of operation, remove the air filter.

First remove the external pipes, then the pipes from the stove radiator in the cabin. The heater hose is cut to fit the size of the nozzles. For ease of fitting onto the fittings, lightly lubricate the surface of the fittings with grease or lithol. First, attach the hose to the fittings of the stove radiator, then to the tap tubes, not forgetting to first put clamps on the hose. Clamps secure the hose to the fittings and tubes. The same actions are performed on the outside of the pipes and fittings. After assembly, check the tightness of the hose clamps on the tubes and fittings.

Pour coolant into the expansion tank, only up to the maximum mark, and replace the air filter. The expansion tank cap is closed. Start the car and warm it up until the cooling fan comes on. Check to see if there are any coolant leaks from the cooling system. With proper repair, there are no leaks. If necessary, add coolant to the reservoir until the average level between the minimum and maximum marks is reached.

What are the advantages of ordering pipes and other auto parts online?

First of all, I would like to note how convenient it is to sit on the couch at home and choose the necessary auto parts for your car. It doesn’t matter what the weather is like outside at that moment. In addition, using the Internet it is possible to buy parts for cars at work. This is explained by the fact that ordering goods online does not require much time. A few clicks of the mouse and products from the virtual car store will be ordered, all you have to do is wait for it to be delivered.

It makes no difference what make and model of the car. There are auto parts for all cars on the Internet. This purchase is beneficial for those who value their time. If necessary, it is always possible to order auto parts from any city. There is no need to worry about their delivery, because this is handled by the courier service. Usually the goods are delivered to the buyer as quickly as possible.

In conclusion, it remains only to clarify that the cost of parts in virtual stores is affordable. The car owner will not have to worry about this. When making a purchase in this way, he will have the opportunity to save money.

Purpose of the heating valve on the VAZ 2113 and VAZ 2115

First, it should be said that the VAZ 2113 and VAZ 2115 cars are equipped with exactly the same heating valves, the design of which has not changed since the VAZ 2108. The purpose of the stove valve is to regulate the flow of antifreeze entering the small heating radiator. The tap can be switched so that the coolant flows through a large cooling circle (this is done in the cold season) or through a small cooling circle (the tap switches to this mode in the summer).

The VAZ 2113 and VAZ 2115 have exactly the same stove taps

Heating tap location

On almost all VAZ cars, the stove valve is located under the central panel, on the passenger side. To replace this device, the panel will have to be removed by unscrewing several screws. The tap is always connected to a pair of rubber pipes held in place by steel clamps.

On the VAZ 2115 and VAZ 2113, the heating taps are located under the central panel on the passenger side

It should also be noted here that before removing the tap, it is always recommended to completely drain the antifreeze from the system. However, an experienced driver can dismantle the faucet without draining the antifreeze (but for a beginner this option is too complicated, so it will not be discussed below).

Modernization methods

Experienced drivers prefer to remove the short-lived heater valve from the system, replacing it with a pair of fittings. During warmer times, a regular water tap is often installed instead (it is recommended to take an Italian one).

Drivers often prefer fittings to the heater valve

The advantage of such modernization is the increased reliability of the heating system. The downside is the inconvenience: to open the tap, you have to crawl under the hood.

Owners of 110 series cars (which include the VAZ 2114) should know that the tap in the heating system is a short-lived thing. Changing it is not difficult - you can do this procedure yourself, without using special tools.

Heating tap malfunctions and their causes

There are a number of breakdowns typical of VAZ heating taps. Here they are:

oxidation. The VAZ heater valve begins to leak due to severe oxidation. It happens like this: in winter the tap is constantly open, antifreeze flows in a large circle, heating the interior. In the spring there is no need for this; the tap is closed and remains in the closed position for 3–5 months. During this time, he manages to literally stick to the pipe. So you can only open it again with the help of pliers. Of course, the tightness of the tap is then broken and a leak occurs;

Antifreeze on a VAZ 2113 flows through the tap directly onto the passenger mat
jamming. The heating valve on a VAZ car, like any other device, can simply exhaust its life and some of its parts will break, making it impossible to close and open the device;
cracking of pipes and loosening of clamps. The furnace tap pipes are made of rubber, which cracks over time (this happens especially quickly if the machine is constantly operated at low temperatures). The steel clamps that secure the pipes to the faucet gradually weaken due to so-called metal fatigue. All this leads to antifreeze leaks, which are visible both in the cabin, under the passenger’s feet, and on the ground under the car.

Rubber pipes of VAZ stove taps often crack in the cold

Features of choosing a heating valve for VAZ 2113 and VAZ 2115

After a faucet breaks down, the car owner will have to replace it. And here a completely logical question arises: which faucet should I buy as a replacement? Let us list the main types of furnace taps and consider their pros and cons:

membrane furnace valve. It is this type of valve that is installed at the factory on almost all VAZ cars, including the VAZ 2113 and VAZ 2115. The reliability of membrane valves is extremely low, and as mentioned above, they are highly susceptible to oxidation. For this reason, it is not recommended to buy a replacement membrane faucet, despite its low price, which starts at 200 rubles;
ball valve It is more expensive than the membrane one (the cost starts from 500 rubles), but its reliability is also higher. At the same time, the ball valve is also made of metal, which means that the problem of oxidation does not disappear anywhere, so sooner or later the car owner will have to open this valve with pliers;
ceramic faucet. The optimal and most expensive option (a good ceramic faucet can cost 1000–1500 rubles). The liquid in such a faucet is locked using a pair of ceramic plates pressed tightly against each other. The driver can forget about the problem of oxidation, since ceramics are inert. This crane is the best option out of all of the above, so if the car owner’s finances allow it, he should choose it.

The best option for the VAZ 2113 is a ceramic stove faucet

How to change the heater tap on a VAZ 2107 yourself

There is an opinion among car enthusiasts that the VAZ 2107 heater valve is replaced when it leaks. This is not entirely true. In most cases, it has to be changed due to jamming, which is caused by contaminants deposited inside. And this unpleasant fact is discovered when you try to open or close it when the ambient temperature changes - in spring or autumn. Of course, there are times when the faucet starts to leak, and there is a wet spot on the carpet under the passenger’s feet, caused by leaked coolant.

In both cases, there is only one solution - immediate replacement of the heater tap. To do this, you need to purchase a new faucet (preferably ceramic), spare rubber gaskets for the faucet and pipe, and a clamp with a diameter of up to 23 mm, if you have not already installed it to replace the factory one. Some owners of VAZ cars install a regular plumbing tap instead of the standard factory heater tap. This option has a number of advantages, but it is not applicable for VAZ 2105 and 2107 cars due to the presence of air ducts that block access to it. Replacing the faucet does not require the use of special tools; you will need:

Key to 7;
Key for 10;
Pliers;
Phillips screwdriver.

Let’s immediately answer the question of what caused the replacement of a conventional faucet with a ceramic one. Practice has shown that a ceramic faucet is better, as it is devoid of all the disadvantages of a standard one. At the same time, it fully complies with all requirements, both in terms of fastenings and throughput. It is for these reasons that experts recommend replacing the standard VAZ heater tap with a new one that has a ceramic shut-off element.

Work is carried out on a cooled engine to avoid possible burns. First you need to disconnect the supply pipe under the hood.

Next, in the cabin we remove the storage shelf and the glove compartment housing, under which there is a heater tap. In VAZ 2105 and 2107 cars, to gain access to the valve, you need to remove the right air duct, while in other classic models there is no air duct.

It is necessary to remove the air duct on a VAZ 2107 especially carefully, since in addition to the fastening nut, which is easily unscrewed with a 10mm wrench, it is held tightly by latches. You should carefully remove the air duct from all latches without breaking them, otherwise the tightness of the air supply system will be compromised and, as a result, its efficiency will be reduced. If, despite all care, the air duct is damaged, it is better to replace it or carefully seal it during assembly. Next, the heater tap is directly replaced:

The bolt securing the control cable casing is unscrewed and its tip is removed from the crane lever;

The two bolts securing the faucet to the stove are unscrewed, and two points must be taken into account: Secure the lower nut in the groove so that it does not fall out. This can be done using plasticine;
When you remove the valve from the heater, some coolant will leak out. Therefore, it is better to place a sponge or rag under it;
The entire structure is removed from the body;
The metal adapter intended for fitting the supply pipe is unscrewed.

The old heater valve has been removed, you can begin installing the new one. This involves replacing the old rubber gaskets with new ones.

The work is carried out in the reverse order and should not cause any difficulties, except for one thing - when fixing the control cable casing, make sure that the movement of the heater valve control lever completely opens and closes it. Otherwise, you should adjust the fastening of the casing until a positive result is achieved. Next, you need to put on and tighten the supply pipe with a clamp.

Before you begin assembling the air duct, you must ensure that the system is tight. To do this, you need to start and warm up the engine. This way, you will ensure that there are no leaks at the heater valve mounting points and remove any possible air pockets in the cooling system. If everything is fine and the coolant does not leak, you can safely reinstall the air duct, glove box housing and shelf. Lastly, check the coolant level and add if necessary.

This completes the replacement of the stove tap. Having done this work yourself once, in the future you will be able to replace the stove faucet without any problems. You just need to remember the features of the VAZ 2105 and 2107 in case you need to replace the tap in other VAZ cars.

The process of replacing a heating valve on a VAZ 2113 and VAZ 2115

Before starting work, you should decide on the tools and consumables. Here's what we need:

working heating tap;
open-end wrenches;
socket wrenches;
six-liter container with new antifreeze;
container for old coolant (the best option is a small basin);
flat screwdriver;
Phillips screwdriver;
pliers;
rags.

Sequence of operations

The machine is placed on an inspection hole or on an overpass. The wheels are securely fixed using wheel chocks. Then the plug under the main radiator is unscrewed, and the antifreeze begins to drain into a previously placed basin or bucket. It should be remembered that completely draining the antifreeze takes from 10 to 20 minutes.

It is convenient to pour antifreeze into a basin placed in advance
Under the hood you need to find two heating pipes. The pipes have steel clamps. The screws on the clamps are unscrewed using a Phillips screwdriver, and the pipes are removed from the tubes manually.

The clamps on the external pipes of the VAZ 2113 are loosened with a screwdriver
In the cabin, on the passenger side, the side panel is removed, under which the heating tap pipes are located. To remove this panel, use a flat screwdriver and a 10-mm open-end wrench. After removing the panel, you will have access to the pipes, which are attached to the faucet with steel clamps. You will need a small flathead screwdriver to loosen these clamps.

To loosen the internal clamps on the VAZ 2113 tap pipes, you will have to remove the side panel
The other ends of the heating tap pipes are attached to the stove radiator. There are also two clamps there. They are loosened with a Phillips screwdriver and pulled off the radiator pipes by hand.
As soon as the faucet is completely free from the pipes (both from the passenger compartment and from the engine side), you can proceed to unscrewing its fasteners. The stove faucet is held on two studs with nuts set to “10”. It is best to unscrew these nuts using a spanner wrench, since there is little space under the side panel.

It is convenient to unscrew the studs of the VAZ 2113 stove pump with a spanner wrench
After unscrewing both nuts, the valve can be removed from the mounting studs. But this must be done more carefully, because a rod is attached to the tap, which will also have to be disconnected.
The cable rod of the heating tap is held on a steel clamp. To straighten it, you need to use pliers.

The rod of the VAZ 2113 stove pump is held on a clamp, which is unbent with pliers
Now the stove tap is removed from its niche, replaced with a new one, and then the heating system is assembled in the reverse order.

The VAZ 2113 stove pump is freed from drafts and pipes and can now be removed

Replacement

Don’t rush to immediately blame the faucet for everything. It often turns out that the reason for the heater not working is damaged pipes. They connect the radiator and the heating device. Therefore, first check their condition.

If the reason is still in the regulator, then proceed with replacement.

To work you will need a certain set of tools and materials:

Clamps 18-22 millimeters;
Coolant;
Empty containers with a minimum volume of 5 liters;
Crosshead screwdriver;
Keys for 10 and 13 millimeters;
Silicone based sealant;
Dry rags;
Inspection hole;
Replacement unit.

Dismantling

If you follow the sequence of operations, then the replacement can be easily done with your own hands.

First, drain the coolant from the reservoir. To do this, unscrew the plug on the cylinder block and place the prepared container under the hole.
To remove the faucet, you will need to dismantle the side flap of the torpedo on the right side, since the desired object is located under the center console. The damper is secured with five bolts.
Wait until the liquid has completely drained out, but do not leave the container too far away.
Find the pipes that are connected from the motor to the regulator.
The clamps should be loosened, and then the tubes should be pulled out. This will allow you to drain any remaining coolant.

Loosen the clamps

Be sure to lubricate the two mounting studs, treat them with a wire brush and brake fluid. This must be done in order to avoid turning the nuts when unscrewing. If you ignore this stage, problems cannot be avoided. This is because the faucet is mounted on bolts, not studs, and the caps fit into a plastic body.

Problematic hairpin

The fastening nuts in this case are self-locking, with plastic rings. So problems often arise with unscrewing them.
After dismantling the pipes, climb into the cabin and use a 10 mm socket wrench to unscrew the fastening nuts of your faucet. If all preliminary measures for processing the nuts were carried out carefully, there should be no problems with their removal.
All that remains is to remove the tap, exerting a slight force towards the passenger, and then remove the latch and the cable responsible for controlling the stove device.

Dismantling works

Installation

Installation of a new stove faucet is carried out strictly in the reverse order. But there are certain nuances here.

Disconnect the cable, then fix the crane to the body;

The cable must be secured in advance using a fastening clamp, since doing this with the regulator already installed will be incredibly difficult.

Requirements for vehicle operation include mandatory sealing of the space between the body and the heater valve with clamps. And when installing pipes, always use silicone-based sealants.

Now all you have to do is tighten the coolant drain plug, return the drained coolant or replace it at the same time, start the engine and let it run for a while.

Only after this try to turn on the stove. If visually everything looks good, there are no leaks anywhere, and everything is adjusted normally, you did a great job, and therefore you can be proud of yourself.

After a few weeks, be sure to tighten new clamps.

This is not to say that such a procedure for replacing a faucet is very complicated. It is quite possible to do it yourself, thereby saving a decent amount of money.

About modernizing the heating tap

As already mentioned, the stove valve on the VAZ is not very reliable. Therefore, some car enthusiasts take radical measures in order to rid themselves of antifreeze leaks once and for all. The simplest modernization option looks like this: an adapter tube is cut out of the tap, and a simple ceramic water fitting with a ball valve is inserted in its place (and car owners prefer to install branded Italian fittings rather than cheap Chinese ones). The resulting design is shown in the photo below.

Car enthusiasts often install ordinary water fittings on their VAZ stove taps.

The advantages of such a replacement are obvious: high reliability and no leaks. But there is also a significant disadvantage: you have to open and close the tap manually. And to do this you will need to stop and climb under the hood every time.

Installing a stove tap directly in the cabin can hardly be called a successful engineering solution, especially if the reliability of the unit is low. So the VAZ owner will definitely have to change the stove valve, and the best thing he can do in this situation is not to wait for the coolant to flow under the passenger’s feet, but to install a ceramic valve immediately after purchasing the car.

Find out how I changed the heater tap of a VAZ 2114 in 20 minutes

The stove valve in the car opens or blocks access to warm air into the car body, thereby regulating the heat supply to the cabin. Sometimes the heating and cooling system refuses to function properly, stops supplying heat, or supplies it in unlimited quantities. What this may be connected with and how to eliminate such malfunctions, you will find out below.

A working faucet is the key to a warm car interior

Why doesn't the stove tap work?

One of the reasons for a non-working faucet is souring. As a result of corrosion under the influence of chemical liquids, the flag loses its mobility, and the tap stops opening or closing. If this happened when the tap was open, then warm air will flow inside even when no one needs it.

Sometimes a failed heater faucet in a VAZ 2114 leads to air in the system, the stove does not heat, and cold air enters the cabin.

But the most common defect is a leaking stove tap. Antifreeze gets into the car body and stains the floor mats. In both the first and second cases, it is necessary to replace the VAZ 2114 heater valve.

If you find antifreeze under your feet, do not rush to immediately buy a new faucet. The leak can come from a burst pipe; even the heater radiator can leak. First, find out where the antifreeze is leaking from, and only then go to the auto parts store to make purchases.

Which faucet is better?

All owners of VAZ 2114, 2115 and other models unanimously claim that the original faucets that are equipped with the stoves of these cars are the most unreliable.

The locking mechanism is a rubber membrane. Aluminum housings are susceptible to corrosion and quickly turn sour. True, the price of these parts is low - 80-120 rubles.

Apparently, the price is calculated on the fact that the faucets will change every season.

Ceramic faucet is considered the most wear-resistant

But car owners don’t want to crawl under the car every time it gets cold, spoil their shoes with leaking antifreeze, and freeze inside the car. Yes, and this is a troublesome task - replacing the faucet on the VAZ 2114 stove. Therefore, motorists give preference to more reliable models of faucets:

ceramic, their locking mechanism is made of ceramic plates, and the body is made of high-quality plastic;
Ball valves, the locking element of which is a ball with holes.

Most VAZ 2114 owners prefer the Yavva ceramic faucet as one of the highest quality and most reliable. Although these models have lower heat transfer than ball models. The latter are susceptible to oxidation, but to a lesser extent than the duralumin models of AvtoVAZ cranes.

Tools for work

To change the heater valve on a VAZ 2114 you will need the following tools:

Pliers,
Double-sided screwdriver (straight and curved),
Socket or socket wrenches No. 10 and 13.

And of course, you need a container for the coolant. Before you begin to disconnect the failed heater tap from the system, you need to drain the antifreeze from the radiator.

How to change the stove tap with your own hands?

You will need a pit to work with because the heater valve is located at the bottom of the hood, under the side trim on the passenger side. Replacing the stove valve on a VAZ 2114 is carried out in several stages:

On the faucet, you need to brush the fasteners, rinse them with brake fluid, and leave them for a while so that the fluid cleans the threads on the studs and the nuts are easier to unscrew. To wash studs, it is better to use WD-40, if available. This is an important stage in the work, because rusted bolts can grab the nut so much that unscrewing them becomes problematic. Sometimes when unscrewing nuts, the bolts need to be held with an additional wrench or pliers.
In the cabin, remove the side trim. Now you can see the pipes leading to the tap. Loosen the hose clamps and remove the hoses one by one. At the same time, keep a container with antifreeze near you, which you immediately place under the emptied pipes so that the remaining antifreeze flows out.
If you decide to replace the hoses, they must also be released from the radiator. But if they are in satisfactory condition, then when you start assembling, you will only need sealant.
Return to the pit and use a 10mm wrench to unscrew the nuts holding the tap in place.
Go back to the body again and try to remove the heater valve of the VAZ 2114 towards the passenger seat. In this position, remove the lock and release the cable that controls the tap.
Now you can install the new faucet. First put the cable on it, secure it with a spring clip, and only then can you screw it into place. Install O-rings between the valve and the body. Use sealant to secure the stove pipes in place. Don't forget to pour the antifreeze back into the radiator at the end.

Replacing the stove valve of the VAZ 2115, as well as the VAZ 2113, is carried out in the sequence described above. The design of the heater in these VAZ models is the same as that of the VAZ 2108.

Replacing the heater tap

The heater tap on a VAZ car is replaced if the heater tap leaks. A sign of a leaking heater tap is the formation of puddles of coolant on the carpet at the feet of the front passenger in the car interior.

With the onset of cold weather, all drivers move the heating switch to the “red” zone, and many immediately discover a puddle of “Antifreeze” under the passenger’s feet. The same thing happened to me in the spring when I turned off the “stove”. So you should touch the delicate tap less often. Better - twice a year, the rest of the time regulating the temperature with the “outboard” air supply damper. But the experienced ones keep a spare unit at the ready.

To complete the job of replacing the heater valve, you will need a new heater valve, a worm clamp with a diameter of 16-23 mm and coolant.

We carry out the work of replacing the heater valve on a VAZ car with a cold engine. In the engine compartment, loosen the tightening of the clamps securing the heater inlet and outlet hoses to the faucet nozzles, and remove the hoses from the nozzles. In the cabin, use a Phillips screwdriver to loosen the tightening of the clamps securing the heater radiator hoses to the faucet nozzles and remove the hoses.

We remove the rod bracket and remove the rod from the hole in the valve lever. In the engine compartment, using a “10” wrench, unscrew the two nuts securing the valve body to the front panel. In the cabin, remove the valve. We assemble everything in reverse order... The faucet was installed in ceramic...

List of new spare parts and tools for repair

VAZ 2115: replacing the heater radiator on your own

High-quality parts that will be needed to replace the heater valve on a VAZ 2115 and similar models 2113, 2114 must be certified by the manufacturer and have original part numbers, which guarantees their compatibility and long service life. To fix this problem, the car owner will need the following spare parts:

New heater valve (art. 21080 - 8101150 - 00) Here it is worth giving preference to a ball valve, which has reliable structural elements and greater heat transfer, in contrast to the ceramic and membrane type.
Two pipes from the tap to the heater radiator (repair kit 237РШ).
Four metal sealing ties (clamps).
A can of coolant compatible with what was previously poured into the vehicle's system.

Repair work is carried out using standard tools, the list of which looks like this:

a set of screwdrivers with a short tip;
open-end spanners 10 and 13 mm;
compact-sized coupling heads with a cardan and a knob;
container for draining old coolant;
sealant;
flashlight for a better view under the torpedo space of the vehicle;
gloves for hand safety.

In official Lada car repair shops, at the end of 2022, the price for replacing a heater valve on a VAZ 2114 is, without taking into account the cost of new parts, from 2000 to 2500 rubles; small, private workshops will ask for about 1500 rubles for the work. The work itself is not difficult and any car owner can do the repairs with his own hands after studying the steps below.

Heating system design

The valve in question allows you to close or, on the contrary, give unlimited access to the engine-heated coolant (coolant) to the heater radiator. To enhance convection, the circuit also uses an electric fan. The latter pumps air, heat exchange occurs, and the temperature in the cabin rises.

The heater tap is located under the dashboard. You can access it by removing the side trim from the front passenger seat.

In the summer, there is no need for a heater, and therefore the damper remains closed, and, accordingly, antifreeze stops flowing into the heater. In this case, the system performs the function of ventilation, and unnecessary coolant circulates through a small circuit and cools in the main radiator.

The tap begins to be actively used in the fall, when the need for a stove arises. It is driven by a special lever mounted on the instrument panel. A drive cable comes from it, which, in turn, is connected to the locking valve mentioned above.

General information about the heater radiator VAZ 2115

In the interior of the Lada of this model, the temperature is maintained at the specified values by a built-in heater, which motorists often simply call a stove. The air heating process is regulated by a special automatic device that provides temperature control with an error of a maximum of a few degrees.

A car radiator, integrated into the heating system, heats the air entering the car interior. There is a handle on the dashboard of the car, with which the driver is able to distribute the air flow passing through the radiator deflector.

The specified radiator, packaged in a plastic casing, is located in a horizontal position under the instrument panel. It consists of aluminum tubes placed in two rows, two tanks (they are made of plastic) and plates pressed onto the tubes. Coolant is supplied and drained through the fittings on the left tank.

Causes of failure

Replacing the tap, in the case of a VAZ, is usually required if it stops working. This happens when it gets jammed. This happens due to the sedimentation of solid particles contained in antifreeze and metal corrosion on its elements.

The second reason is the appearance of a leak. It occurs after the membrane loses its tightness.

In both situations there is no choice - you have to start repairing. It is almost impossible to repair the faucet itself - it is simply replaced with a working one. The procedure is not complicated, but it is advisable to carry out all the work together with an assistant.

A leaking stove tap needs to be eliminated as quickly as possible, as it can cause many problems. The leakage of antifreeze directly into the cabin is the most insignificant of them.

More trouble will be caused by a lack of coolant in the engine cooling system - because of this, it can easily fail.

So, if the cabin suddenly smells of antifreeze, and a wet spot appears under the rug, then, first of all, it is the faucet that needs to be checked. Arm yourself with a flashlight and, having removed the side panel from the center console (passenger side), look into the opened niche. Please note that there may be a leak from the radiator, as well as from the pipes, which means it wouldn’t hurt to inspect them. However, more often than not it is the faucet that is to blame.

Causes and symptoms of malfunction

The heater valve breaks for two reasons:

Locking devices become sour. Because of this, the driver cannot open or close the tap. Oxidation provokes sticking of the locking elements to each other. If you use force, you risk breaking the locking devices. This is not so scary in the warm season, since air flows can be controlled by dampers. How to check the faucets of the VAZ-2114 stove for souring? Just give it a spin. If this requires a lot of force, the element is worn out and needs to be replaced.
Violation of tightness. Depressurization entails a leak of coolant. Such a breakdown is indicated by a decrease in the coolant level, the appearance of a smell of antifreeze or antifreeze inside the car, the formation of greasy spots on the windshield and traces of coolant on the floor (in the glove compartment area, at the feet of the front passenger). Checking for leaks is easy. If it is broken, you will notice it immediately by characteristic signs.

Important! The stove faucet has a non-separable body. Therefore it is impossible to repair it. If an element breaks, you only need to replace it

If an element breaks, you only need to replace it.

When the warm season arrives, the tap is turned to its extreme position. Being in this state for a long time, it can turn sour, as a result of which it will be very problematic to regulate. If you use force, the crane can be broken. Such a breakdown is not critical - the car will still be drivable.

Works, but leaks

Over time, the O-rings age, causing the faucet to not close completely. The consequences of this may be:

Lowering the fluid level in the distribution tank. With such a “symptom”, the tap needs to be checked urgently, because the tank also supplies the engine cooling system.
Wet carpet in the cabin.

To check the faucet for leakage, you need to bend the mat

A grease mark on the bottom of the windshield.

When checking, pay attention to the underwater hoses. Over time they may become thinner

souring of the locking device;
depressurization of the housing (leaking).

In the first case, it turns out to be impossible to open or close the tap. Oxidative processes inside lead to the elements of the locking mechanism sticking to each other.

Using force to remove constipation can lead to its complete destruction. This breakdown is not critical, and allows you to operate the car in the warm season. It is enough to simply block the flow of air into the cabin using a damper.

decrease in coolant level;
presence of a characteristic odor in the cabin;
the appearance of a greasy coating on the windshield;
traces of coolant on rubber mats or carpet under the glove compartment.

It is worth noting that the heater valve has a non-separable body, which is why it cannot be repaired. Only replacing it will help here.

There are three faults in the valve of the VAZ-2114 stove, but if they occur, the unit must be replaced, since it cannot be repaired.

Crane breakdowns:

Incomplete opening/closing of the channel. It occurs due to wear at the junction of the axle and the shut-off valve. As a result, a significant backlash appears, due to which, even when the valve lever is moved to the extreme position, the damper does not open the channel completely. This malfunction negatively affects the performance of the stove.
Gate valve jammed. This happens because the tap has not been used for a long time and the moving element has become stuck and does not move. Attempts to open with force result in the rupture of the connection between the axle and the valve or the formation of strong backlash, which causes the valve to also become inoperable.
Loss of tightness. The tightness of the unit is ensured by seals on the damper axis. If these elements are worn out or damaged, the liquid flows out through the mounting hole of the axle. This malfunction does not affect the performance of the stove, but antifreeze leaks will appear in the interior.

The first two faults can only be identified visually by removing the valve from the car. As for the loss of tightness, a symptom of a breakdown will be traces of antifreeze on the floor mat in the cabin. And since a leak can occur due to leaks at the junction of the pipes with the heater elements, when leaks appear, first of all, find the location of the leak. If the faucet leaks, there will be traces of antifreeze on the body.

Preparing for replacement

First of all, buy a new faucet. Experienced car mechanics recommend not using the standard product installed on the VAZ-2115 by the manufacturer. Buy a ceramic element and an additional set of gaskets for it.

You will also need:

can of VD-40;
keys for 13 millimeters and 10;
Phillips and flathead screwdrivers;
a bucket or basin with a capacity of at least 8 liters;
sealing compound (neutral silicone).

If the antifreeze has not been changed for a long time, then purchase it in sufficient quantities, because in order to replace the faucet, the old one will have to be completely drained from the system. And finally, install the VAZ-2115 on a pit (ramp or lift) - you need access to its bottom.

Repair process

Please note that replacing the VAZ 2114 stove (that is, the radiator) can be done in 2 ways: with removing the dashboard and without dismantling the dashboard. Professionals prefer the first method

That is, master mechanics of any service station replace the radiator with a 2114, having first disassembled the top down to the screw. Only someone who has already assembled and disassembled the dashboard with their own hands can handle this work. There are a lot of subtleties and nuances.

Speaking for us, we will replace the VAZ 2114 heater radiator without removing the dashboard.

But again, only highly qualified craftsmen can qualitatively change the design of the machine. We won't interfere there, out of harm's way.

For this job we will need:

Screwdriver Set
A set of keys
A pair of new clamps for the diameter of the radiator pipes
New radiator. By the way, it’s better to take something imported, for example, Fenox RO0004C3 (it costs twice as much as the original)
New antifreeze for the heating system

Now let's look at the question of how to replace a VAZ 2114 stove without removing the panel (not the entire stove, but only the radiator).

We turn off the car, open the hood, remove the wires from the battery and place a container under the antifreeze drain from the stove
We switch the temperature controller to the strongest heating mode

Slowly unscrew the plug for draining the liquid from the heating circuit. If you remove it quickly, antifreeze may splash on the generator. Some also unscrew the cap on the antifreeze tank itself so that the liquid drains faster

We go into the salon and move the seats towards the rear seat, recline the backs, cover the seats with a large piece of oilcloth, and lay an old blanket on top

Unscrew the central pillar. We unscrew the fasteners to the floor (on the right and left sides) the self-tapping screw on top the side fasteners

Please note that some screws are covered with a plug.

We remove the glove compartment (the photo below shows its mounting diagram)

We unscrew the dashboard mount so that the entire dashboard shakes. This point is important for removing the radiator. That is, in order not to remove the entire tidy, we will simply move it away without disassembling it down to the screws. Replacing the VAZ 2114 heater radiator continues

Now we have access to the adjustment cables for the heating tap of the stove. Remove the ends of the cables on the driver's and passenger's seats. They simply fall off the eyes of the adjusting levers

Removing the radiator protective casing

Remove the clamps securing the pipes (can be from the hood or from below)

Now, in order to replace the VAZ 2114 stove without removing the panel (that is, the radiator), you will need a partner. Together with the second pair of hands, we lift the dashboard a little and pull it towards ourselves to take out the old radiator and push the new one in there. You need to be extremely careful at this stage

The torpedo must be moved with the utmost care so as not to damage anything anywhere.

We assemble the new radiator in the reverse order (clamps, cover, cables, etc.)

We recommend: What the markings on rims say: explanation of symbols, overview of parameters, selection tips

Pay attention to one more point. Having put everything back together, you need to fill the circuit with new service fluid.

After refueling, you need to bleed the heater (heat the interior), then turn off the engine and, if necessary, add antifreeze to the tank.

Replacement procedure

First, make sure that the car engine has completely cooled down, since working with hot coolant is not only difficult, but also dangerous.

If the engine is cold, then immediately go under the vehicle with an empty container. Initially place it under the radiator. Unscrew the plug from the last one. Next, in the engine compartment, slowly unscrew the distributor tank cap. When the coolant drains, move the bucket under the cylinder block - it also has a drain. Its location: directly behind the ignition module.

When there is no antifreeze left in the system, tighten all the plugs and the distribution tank cap and begin removing the pipes. They are held in place with clamps. To loosen the bolts on the latter, you should use WD-40 and a flat-head screwdriver.

Remove the freed hoses from the hood side with great care - there is usually some coolant left in them. Drain it into a container.

Now go directly to the salon. Remove the screws securing the side insert of the center console on the passenger side. Having gained access to the tap, disconnect the pipes from it, also being careful (put a rag on the floor in case of antifreeze leakage).

At the bottom, unscrew the nuts securing the faucet - they require a 10 mm socket wrench. After this, return to the VAZ salon and carefully pull the heater tap towards you. Next, disconnect the cable drive from it by first removing the spring clamp. When installing a new device, do not forget to install fresh gaskets, as well as the seal located at the junction of the part with the body.

Before fixing the stove tap, connect a cable to it, since this will be inconvenient to do later. Replace the pipes, treating their ends with a sealant, and tighten the clamps thoroughly, but do not overdo it - the plastic body of the faucet may crack. The hoses are fixed in the engine compartment in a similar way.

After replacement, fill in with fresh coolant, close the hood, turn on the engine and check if the heater is working and if antifreeze is leaking somewhere.

Work order

To replace the heater tap of VAZ 2114, 2113 and 2115, the car must be installed on a site convenient for work (preferably indoors). Repair algorithm:

Drain the coolant. This must be done on a cold engine. Old antifreeze is drained into the container through a plug located in the front of the car at the bottom of the crankcase.

Dismantling the pipes must be done carefully; it is advisable to lay old rags on the floor, which will absorb the remaining volumes of spilled antifreeze.

After removing the pipes, unscrew the 2 nuts on the studs with a wrench. The faucet is now fully accessible

All that remains is to disconnect the cable that controls the damper and remove the old part. Please note! The radiator seats are made of plastic - high temperatures often cause them to “sour”. Therefore, they must be removed carefully. If the work is done carelessly, the housing can be damaged.

Install the new part in its original place by tightening the appropriate nuts. The installation sites of the pipes must be treated with a hermetic compound. They are mounted and carefully tightened with metal ties. Also clean the radiator installation areas and cover them with a sealing compound. Perform similar manipulations on the tap, and then complete the installation of the new spare part and secure it with ties.

You can also watch the replacement of the VAZ 2114 faucet in the video:

Replacing the stove radiator

It would also be useful to talk about this procedure. It is not very difficult, but it takes a lot of time.

The procedure is as follows:

disconnect the negative cable from the battery;
remove the dashboard and steering column trim;
also remove the glove box, the plastic from the center console, the ECU, the air duct, the casing that covers the heater and the air conditioner evaporator (if there is one).

After this, direct access to the radiator opens. It is inspected for leaks, and if any are found, the element is replaced with a new one or repaired.

Repair and replacement

Over time, the car wears out during operation, and at some point certain malfunctions appear. A heater failure is most often indicated by a specific murmur. This is often accompanied by oil leaking into the cabin. Its stains are usually found under the right seat on the carpet. All this indicates that the control valve or the radiator itself has probably failed. Malfunctions of the draft can also worsen the operation of the stove - this is usually indicated by cold air coming from the side deflectors. The problem is eliminated by adjusting the cables.

The most common cause of radiator failure is a leak. As a rule, the problem is found in those places where plastic parts are connected to metal ones. If the hole there is small, then the radiator will not be difficult to repair - just add a special composition to the antifreeze, which is sold in almost any car store. With its help, the gap actually closes itself.

The main task is to get to the faulty elements. Access to the tap is fairly easy, but it will be much more difficult to get to the radiator.

In this case, you must first perform the following steps:

remove the negative terminal from the battery;
drain the antifreeze into a prepared container;
The cooling liquid located in the cylinder block is poured into a separate container (it has a special hole closed with a plug).

It is located in close proximity to the ignition unit. If it does not allow it to work normally, it is better to remove it completely. The plug is screwed together with a 13 mm socket wrench.

Next, you will need to dismantle the casing protecting the steering shaft and turn off the emergency lights. After these manipulations, it will be possible to remove the bolted side screens from the console. This, in turn, will allow the glove box to be pulled out. Then remove the diagnostic connector cover. It will also need to be removed - it is attached to two screws on the dashboard.

After this you will need to dismantle:

cigarette lighter terminals and its illumination;
heating regulator unit;
radio

Now comes the turn of the instrument panel. It is held in place by 7 screws. Some of them are hidden under decorative caps. If you do not remove them all, then there is a possibility of breaking this element, made of ordinary plastic.

As a result, access to the central bracket opens. It is secured with two bolts, and to unscrew them you will have to use a size 8 wrench. Moving the bracket aside, you need to disconnect the ECU terminals.

Finally it’s the turn of the radiator. To remove it, you will have to loosen the clamps holding the pipes extending from the above-mentioned unit. However, you should not completely disconnect them, as coolant will most likely flow out, which can easily ruin the decorative floor covering. It would be best to install a basin underneath or, at worst, cover everything with film.

The radiator is held in place by three screws. The heating part that has become unusable is replaced with a new one, and all the above-described manipulations are repeated in reverse order.

Repair of VAZ 2114 crane

As a rule, faucets are not repairable and if they become sour, leak, or changing the lever does not produce the desired result, they are replaced. This is much faster than trying to repair it. But what if it is not possible to buy a new faucet, and the problem has already occurred? Then there is only one way out - to try to repair the heater control valve. When liquid runs out from under the rod, you, of course, are unlikely to be able to somehow eliminate this, because only a few can select bushings or machine a new rod and sealing rings. But if the through pipe bursts or shrinks, then installing a tube of the same diameter into it and coating it with sealant will help for a while.

In the case when we are dealing with plastic, the cause of the leak is a damaged rubber membrane; the problem is also fixable, although not simple. You need to remove the valve from the heater and disassemble it. You will have two parts: the body itself and the lid with a cone and cuff. To remove the cover from the body, it is necessary to cut off the rolling belt from the side of the cover. The easiest way to do this is with an electric drill, in the chuck of which you attach a chisel or scraper.

Where to loosen the clamps

Next we have to do the flaring. To do this, drill 4 holes through (size from 0.1 to 3 mm.). This should be done strictly along the edge of the rolling. Do not allow the drill to deviate towards the middle of the cover. If this happens, further work on repairing the VAZ 2114 crane will be greatly complicated due to damage to the sealing band located on the seating surface of the cuff in the body.

The next step is to drill out the rivet that is in the cone, remove the old cuff and the remains of the rivet. You will get a hole where you need to make an M4 thread.

The new cuff can be cut from a car inner tube (preferably from a truck). The heater valve must be in the closed position. Next, you need to cut along the contour of the cover (top), making four holes for fasteners at their location (along the edges and in the middle).

A new cuff is secured to the top of the cover using a screw (M4 - the hole for it is already ready), as well as the valve itself, then you need to align the holes and tighten them with screws (M3). In this case, the nuts will be on the side of the cover.

Inlet pipe

In general, the work on repairing the VAZ 2114 heating tap is completed; now we check the tightness by first closing the outlet channel and blowing from the inlet pipe.

Think about whether you have the strength to repair it yourself? No? Then there is only one way out - only replacement.

Checking the functionality of the heater tap

If the cold or hot air supply modes do not switch, the cause may be a loose damper control cable or souring of the mechanism itself. How to open the tap of the VAZ-2109 stove in this situation?

To do this, you need to remove the side panel of the dashboard on the passenger side. Then check the condition of the cable and if this is the reason, then connect it back into place. You can also, without removing the panel, put your hand under the dashboard, where the VAZ-2109 heater tap is located, and move the VAZ-2109 heater damper lever to the desired position. If the lever does not give in, then most likely it has gone sour and must be replaced.

Removing and replacing the heater valve

To replace the VAZ-2109 heater tap, you need a set of tools available to most drivers:

a set of Phillips and slotted screwdrivers;
a set of open-end wrenches No. 10 and No. 13 or socket heads of these sizes, as well as a wrench with a ratchet mechanism and a cardan;
silicone sealant;
container for draining coolant;
metal brush;
universal penetrating lubricant WD-40 or its equivalent;
inspection hole, overpass or lift;
rags to protect the interior flooring from antifreeze.

Ceramic, ball, and electric valves for the VAZ-2109 stove are available for sale. Which heater valves for the VAZ-2109 are better than those listed? With rare use, ball mechanisms are more susceptible to souring, and the electronic automatic heating control system “SAUO” is much more difficult to install. Ceramic mechanisms produced in Russia or “LUZAR” are free of these shortcomings.

Many experienced drivers advise simply replacing the heater taps with water taps. The benefit of this solution is not only in cost, but also in reliability - the coolant either constantly circulates or is easily closed manually at the pipe. Another way to make it easier to change the heater faucet of a VAZ-2109 is to abandon it altogether; the cabin temperature in this case is regulated by air dampers.

Instructions on how to change the heater tap of a VAZ-2109:

Before replacing the valve of the VAZ-2109 heater, place the car on an overpass and, unscrewing the cap on the radiator, drain the coolant into a container prepared in advance.
When the radiator is empty, use a screwdriver to loosen the clamps on the pipes going from the engine to the heater, then use WD-40 and a metal brush to clean the threads on the studs securing the part to be replaced. When finished, completely unscrew the clamps.
Carefully remove the hoses one by one; they may contain residual antifreeze that needs to be drained.

Important! Do not skip this step, because it will not be possible to remove the valve of the VAZ-2109 stove with the hoses connected

Having removed the side trim of the torpedo from inside the cabin, check the condition of the pipes and change them if necessary.
Then, under the car, using a socket wrench No. 10, unscrew the nuts securing the part to be replaced on the VAZ stove
Returning to the car interior, pull the faucet towards you (where the right passenger seat is), remove the spring clamp and disconnect the control cable from the part being replaced.
We take a new spare part and reassemble it in the reverse order.

Important! To prevent future leakage of coolant at the joints of the pipes, it is necessary to treat it with silicone sealant, and also to increase the service life, install rubber seals where the heater faucet is located on the VAZ-2109. We make sure that the radiator plug is in place and fill it with coolant to the required level

Then we start the engine and, having gotten rid of air pockets, check the proper operation of the heater modes. This completes the replacement of the VAZ-2109 heater valve

We make sure that the radiator plug is in place and fill it with coolant to the required level. Then we start the engine and, having gotten rid of air pockets, check the proper operation of the heater modes. This completes the replacement of the VAZ-2109 heater valve.

Having learned how to replace the heater tap, you can repair your car yourself, without visiting a service station and avoiding unnecessary repair costs.

Prevention of breakdown of the VAZ 2114 crane

Following a few useful tips will help extend the life of your heater tap.

In order to prevent the faucet from turning sour, it is necessary to periodically move the closing/opening lever of the faucet from one position to another. This problem is especially relevant when the seasons change, when you drive all winter with it open, and in the summer you turn off the supply. By the way, in the heat or when you have to drive in low gears, in order to avoid engine overheating, it is recommended to slightly open the heater valve (move the control lever to the “red zone”), but to prevent heat from the radiator from entering the cabin, completely close the air damper.

Modification of the heater tap

On some faucets (in particular, very often these are Luzar and YAVVA), not only the locking mechanism itself can break, but also the plastic tube can burst, so to make the faucet last longer, you can select the diameter and insert an additional tube . Recently, the box from Luzar already has such a through tube and it is made of brass. According to many experienced car owners, installing a YVVA faucet without modification makes no sense at all - the passage pipe is flattened. And in its through tube it is necessary in any case to install a long (thin-walled) tube with an outer diameter of 15 mm.

It also goes without saying that regular preventive inspection of components is necessary - timely detection of problems will not only minimize your costs, but will also protect your health and that of your passengers from danger, since antifreeze vapors are highly toxic!
