How to change the pipe on the stove of a VAZ 2114

How to independently remove and replace the stove on a VAZ-2115

Heater malfunctions in any car cause a lot of trouble.
It is especially difficult to correct the situation when the problem has already started and coolant has leaked. Replacing a heater on a car is not an easy task, since in order to get to it, you will have to disassemble half the car and it will take a lot of time. Unfortunately, not everyone knows how to remove and replace the stove on a VAZ-2115, and therefore they turn to a car service center.

But you shouldn’t rush to give your car into the wrong hands because of this procedure alone, because:

Work to replace components costs about 1500–2000 rubles.
It’s not a fact that they will do everything efficiently.
Very often, car service workers treat their work anyhow and can break something when dismantling the panel.

Cooling system pipes for VAZ 2110, 2111, 2112 (video)

Cooling system hoses VAZ 2110, 2111, 2112…

Hello dear readers of the blog RtiIvaz.ru. Today I want to continue the conversation about the auto radiator pipes of the cooling system of the VAZ Lada 2110 “ten”, Lada 2111 “eleventh” and 2112 Lada “twelfth”.

In the previous auto article, we looked at the radiator hoses of the cooling system of the VAZ 2108, 2109, 21099, 2113, 2114, 2115. We looked at the video and photos and found out what the sets of pipes of the “eight”, “nine”, “ninety-nine”, “thirteenth” are , the “fourteenth” and “fifteenth” Lada models differ from each other.

What is a radiator in a car:

A device for removing heat from the liquid that circulates in the engine cooling system.

We determined the “upper” supply and also found out which “lower” coolant outlet was a thick rubber hose. You have found out where which rubber tubes fit, today we will continue to look at the video of the Lada 2110, 2111, 2112 pipes.

The cooling system pipes are such a thing that they always seem to be in good condition, but they make themselves felt when you don’t expect them.

You've probably seen cars on the road more than once with their hoods open in a cloud of steam.

So the coolant floats, falling on the burning engine parts (exhaust manifold), escaping in a fountain through a burst rubber pipe.

Therefore, guys, be vigilant if you haven’t changed rubber hoses for a long time. Don’t tempt fate—guessing whether you’ll be lucky or not will be unlucky—but replace all the rubber hoses of your car in advance.

What kind of outlet and inlet rubber hoses of the VAZ 2110, 2111, 2112 radiator are they, look at the video and photo, friends...

Look at the photo on the left, numbered -1, the rubber tube supplying coolant is the “upper” one, and numbered -2, the rubber tube is taking out the “lower” coolant. Numbered -3; -4 “shorts”, one of which is a bypass from the block head to the water pump, and the other “short” is a connecting coupling.

The considered pipes on the left are suitable for VAZ cars of the “tenth” family with carburetor and injection engines.

Design numbers:

2110-1303025 radiator supply hose, number -1 (see photo)
2110-1303010 radiator outlet hose, number -2 (see photo)
2108 -1303092Р coupling connecting the thermostat and water pump, as well as the bypass “short”, numbers -3; -4 (see photo)

Next, look at the photo on the right under number -5 for the coolant supply pipe on the “top”, and at number -6 for the outlet pipe. cool liquid "bottom". You see number -7, the so-called “long corner” bypass pipe. cool liquids.

These pipes on the right are for Lada VAZ-2111 and Lada VAZ-2112 cars with an injection engine. There are also the longest “upper inlet” and “lower outlet” pipes on the VAZ-2112 with a 16-valve engine.

Design numbers:

2112-1303025 radiator supply hose, number -5 (see photo)
2112-1303010 radiator outlet hose, number -6 (see photo)
2108 -1303092Р coupling connecting thermostat and water pump “shorty”, number -8 (see photo)
2109-1303093-01 connecting hose for thermostat and water pump bypass “long angle”, number -7 (see photo)

Next, friends, watch the video: https://www.youtube.com/watch?v=FiguPVa2ulQ Dear car enthusiasts, did you like my previous publication? How do you feel about this? Should I continue the topic of rubber pipes for the cooling system of VAZ cars?

What is a silent block?

Why does the stove blow cold air? Causes of malfunction

In the interior of the VAZ 2110 you can quite often see that the heater simply does not respond to the temperature regulator. The answer immediately suggests itself - one of the elements of the system has simply failed. We start looking for him.

Problems with the interior temperature sensor

First of all, we check the interior temperature sensor. It is located on the ceiling, near the interior lighting. If the temperature regulator is turned to the extreme right position, and the stove reacts to this, then the sensor needs to be changed. If everything is fine, we look further.

Problems with the heater damper

The heater damper may oxidize and jam. Many experienced owners of these cars install an aluminum damper, which better distributes air and retains heat in the cabin. But you can only get to it from under the hood.

If the stove on a VAZ 2110 blows cold air, but is itself heated to a temperature of 90 degrees, then the reason is hidden in the standard air ducts. Most likely, they are either damaged or have fallen off from the stove itself. And to get to them you will have to disassemble and remove the entire panel. If you still cannot restore them, you can simply replace them with corrugated hoses purchased from building materials and install them. And seal all joints tightly and thoroughly with polyurethane foam or modelin.

The heater radiator is clogged

If the stove on a VAZ 2110 blows cold air, then there is only one reason - the stove radiator is clogged. If the engine is cooled with water, then rust can form in the radiator, and at high temperatures, scale can also form. Small pipes in the radiator can become clogged if you (accidentally) mix antifreeze with antifreeze, this mixture will simply curdle. In addition, some short-sighted car enthusiasts add a special radiator sealant to the coolant, which also clogs the radiators from the inside. It's quite easy to check. You need to warm up the engine to a temperature of 90 degrees, turn on the heater and check the inlet and outlet pipes of the heater by touch. If the temperature on them is different, then the radiator is simply clogged and must be replaced. But the process of replacing it is quite labor-intensive.

The heater fan is broken

The stove fan may fail. Both he and his fuse are checked.

The gasket between the head and the engine block may be broken, allowing coolant to enter the cylinders. As a result, the coolant level may drop. If thick white smoke comes out of the pipe, then the gasket is definitely broken and requires immediate replacement.

If the cabin filter is clogged with dust, then there is no or almost no cold air intake to the fan of the VAZ 2110 stove. It must be immediately taken out, cleaned, and if that fails, then replaced with a new filter.

There may be a low level of antifreeze or antifreeze and there is simply not enough for the stove due to air locks in the cooling system. When the pump squeezes out and expels this plug from the system, you must add liquid.

Thermostat failure

The most common reason why the stove on a VAZ 2110 does not heat with hot air is the thermostat. It just starts to stick in the upper or lower position over time. If this happens, then you just need to replace it. But the same situation can happen to a new one. So what should we do then, change it again? There is a proven way to bring a stuck thermostat back to life.

To do this, you will need to park the car on a slight slope. In this case, the front wheels must be 25–35 cm higher than the rear wheels. The engine must be running. You need to open the hood and prepare a small wooden (precisely wooden, to avoid damaging the thermostat) stick, or the handle of a shovel. Now, once you get behind the wheel, you need to change the gas 2-3 times. Immediately go out and tap the thermostat with the butt of a stick. After this, touch all incoming and outgoing pipes near the thermostat. Such manipulations need to be carried out 3 – 5 times, after which the thermostat will work like new again.

Cracks in pipes and pipes

Another serious malfunction of the stove is coolant spilling out under your feet. There are usually two reasons. A leak in the radiator or a crack in the pipes. It is best to replace both elements, since repairs and sealing them will cost longer and more expensive.

The upper pipe is inflated

I changed the cap, checked the thermostat, poured it into the tank, and sucked it out as it cooled. It seems that the air in the cooling system should be removed on its own. What could be the problem? The pipe is hot, the temperature remains in the middle of the scale.

The coolant arrow does not show the temperature correctly - 1 answer

When it’s hot, that is, on a warm engine (CAREFULLY with a large piece of rag, open the lid, gradually bleeding air from the system), then put it on and it will inflate already in a warm engine. Can you imagine what happens when a car moves along the highway, at revs?

On Japanese ones, the air came out once or twice, if everything is in order, the air in the system simply has no place to come from.

It inflates for everyone, some more, some less. The temperature rises, and accordingly the pressure in the system also increases. Have you tried warming up the car to the opening temperature of the thermostat, when the lower pipe becomes hot?

As it cools, the air does not escape, but rather enters the expander, because the valve in the lid is bidirectional. In one case, it is triggered when the pressure in the system increases (during overheating). In another case, the valve allows air into the system when the coolant cools, so that a vacuum is not created in the system and the hoses are not flattened.

Thus, on a cold engine, the system must have atmospheric pressure, no more, no less. And if you have an air lock somewhere in the system, then it can remain there for a long time if it is not helped.

Radiator pipes VAZ 2114

Next comes the upper radiator inlet pipe, connecting the radiator to the engine block head.

This hose goes to injection engines. Its internal diameter is 32mm, see catalog number 21082-1303025.

The next one is the lower radiator outlet pipe, which connects the radiator to the engine cooling system thermostat.

Its catalog number is 21082 – 1303010, internal diameter is 32 mm.

“Angle” pipe for connecting the thermostat to the water pump (pump).

Catalog number – 2109-1303093-01. This pipe fits almost all front-wheel drive VAZ models.

The expansion tank pipe is popularly called the “filler pipe.”

It serves to connect the expansion tank to the thermostat. Through it, antifreeze enters the cooling system when the system is filled or topped up through the expansion barrel. See catalog number 21082-1303080 for its number.

Stove pipes VAZ 2114

The pipe that connects the heater to the block head is often called “big goose” in everyday life because of its resemblance to this bird.

The hose supplies coolant from the block head to the heater radiator. We look at the catalog number 2114 – 8101206.

These considered rubber hoses are reinforced, except for the throttle heating hoses and antifreeze steam exhaust hoses.

The goose curve hose is located under the hood of the car and serves to drain coolant from the heater radiator to the water pump.

Catalog number of the crooked goose 2114- 8101208, factory BRT.

The “short” pipe connects the thermostat to the engine block head.

Shorty catalog number 2108-1303082, BRT plant.

The “small” cabin pipe of the stove supplies coolant to the radiator of the stove, through the tap, from the “crooked goose”.

Its VAZ catalog number is 2114-8101200 from the BRT plant.

The cabin “large” outlet pipe is designed to drain coolant from the heater radiator through the “big goose” hose to the water pump.

Catalog number 2114-8101204 from the BRT plant.

Under the hood, the “big goose” supplies coolant to the heater radiator through a tap. And it takes the liquid to the pump from the radiator of the “goose curve” stove through the “large” cabin hose. For example, thanks to a set of rubber pipes, coolant circulates through the heater radiator.

The rubber pipe, the so-called injection “breather”, serves to connect the valve cover of the block head with the “snail” (2111) for supplying air to the engine.

The upper catalog number of the factory breather is 2111-1014058-10.

All connections presented in the video are located under the hood and in the interior of the VAZ 2114 car, related to the cooling system. In addition to the large breather pipes, small breather pipes and volutes, which serve for the passage of air.

The car also contains well-known gas supply hoses, brake hoses, a vacuum hose, as well as windshield washer fluid supply and others. They will also need to be viewed on video and described in the article.

All rubber hoses in a car need constant replacement, as they are exposed to aggressive liquids and gradually lose their properties. They lose their elasticity, become tanned, crack and sometimes break when used for a long time without replacement.

Therefore, it is recommended to periodically review their condition and replace them if any malfunction is detected.

This video ends the review; I hope that the video will be useful to someone both for information and when servicing their car.

The design of the VAZ 2110 cooling system

The main function of the cooling system is to maintain the engine operating temperature at 98-103°C. When the engine is running, the heat of the working parts is removed using coolant that constantly circulates in the system. While the engine is heating up, antifreeze or antifreeze moves in a small circle without passing through the radiator. The thermostat is closed at this time.

When the operating temperature is reached, the thermostat opens and the liquid circulates in a large circle. Both pipes become hot. The radiator promotes greater cooling by air flow. The fan increases the cooling intensity. The pump ensures continuous circulation. The thermostat regulates the amount of fluid supplied to the system.

For efficient operation of the VAZ 2114, 2115, 2110 engine, various indicators are taken into account:

oil temperature;
coolant temperature;
outside temperature, etc.

The functioning of the cooling system is controlled by the engine management system, which collects all specified parameters.

A cold lower radiator pipe on VAZ 2110, 2114, 2115 does not always indicate a problem in the system. With a cold engine, before the large circle opens, it should not heat up, since hot fluid does not flow to the radiator. The thermostat can block circulation in a large circle in the cold season, when hot air from the coolant enters the car interior, causing it to cool faster

You need to pay attention to the cooling system if the radiator pipes remain cold when the internal combustion engine reaches operating temperature and it overheats.

To check the efficiency of the system in cold weather, it is recommended to drive the VAZ 2110, 2114, 2115 into the garage, let the engine warm up with the cabin heater closed for 10-20 minutes, and only then draw conclusions. If even under these conditions the pipe is cold, you need to look for the problem.

Copper stove radiator

Initially, copper has a heat transfer equal to 389.6 W/(m deg), takes a long time to heat up, and takes a long time to cool down.

The number of fins is significantly less than that of aluminum, the channels are small and quickly clog, poor fluidity at idle (by the way, this is why cool air blows at idle - the most common problem among owners of the domestic automobile industry). The copper radiator is repairable; in case of leakage, it can be soldered.

It is also worth noting that recently for the manufacture of copper radiators they use not pure copper; some paint it, which reduces heat transfer. Today there are very few high-quality copper radiators on the market, so it’s easy to run into the last slag.

What are the air filter pipes for?

As you know, in a car, to obtain a fuel-air mixture, clean air is used, filtered from dust and other components of the outside environment (insects, abrasive dirt, etc.). If, for example, grains of dust enter the cylinder through the combustion chamber, they can damage its surface or rings. The contact density between these parts will be disrupted - compression will decrease and engine power will drop. In addition, oil will remain in the scratches of the cylinder, which will burn, which will lead to the appearance of smoke in the exhaust gases and the need to add lubricant due to its burnout. Therefore, the air is supplied through a special filter, where it is cleaned.

In addition, the engine “does not like” hot air - everyone has noticed that in the heat of summer, the power and throttle response of the engine decrease and it seems to reluctantly accelerate the car. Therefore, the air filter is not installed directly on the engine, but with some offset - in the place that the designers and developers were able to allocate for it in the engine compartment, but as far as possible from the heat of the engine and the oncoming air flow passing through the radiator of the cooling system. Air is supplied from the filter to the engine through a pipe.

In cars with a filter located near the radiator frame, air intake pipes are additionally installed in the corner between the fender and the front panel of the engine compartment. They are connected to the filter inlet and are positioned in such a way that air flows into them freely and as cleanly and coolly as possible. That is, their air intake ends are placed in front of the radiator, further and higher from the wheels, in a closed space, if a filter is installed in it and where circulation is disrupted. This provides not only a good supply of cool air, but also protects the filter from road dirt and debris:

Air intake is carried out in the structurally permissible area of the engine compartment, which is as safe as possible for the likelihood of dirt and dust entering.
If there is something in the incoming air, then some of the small debris (dust) and most of the large debris will settle or be retained in the intake pipe, and then fall out themselves.

Thanks to this, the air filter will be able to serve the period intended for it by the manufacturer.

When does the reason lie in the cylinder-piston group?

If the cylinders are destroyed or compression rings occur, then part of the energy of the explosion of the mixture in the cylinder will be directed directly into the crankcase along with the exhaust gases, which will create excess pressure in it. But in this case, the corresponding accompanying signs of such a malfunction will be observed:

difficult engine starting;
its unstable operation at idle;
reduction in engine power;
compression in the cylinders is lower than stated by the manufacturer;
exhaust smoke;
other.

In this case, you will have to contact specialists so that they can carry out additional diagnostics of the engine and, if the preliminary diagnosis is confirmed, carry out the necessary repairs. But this should be done only after all other methods of eliminating oil from getting into the pipe have been checked and tried. If they help, then it is possible that not everything is so bad with the engine and it only needs to be given much less attention and care than it seems at first glance.

Stove (heater) pipes for VAZ 2114 “BRT” (4 pieces) No. 87i are original pipes that will last the required period. Planned replacement of pipes 3 - 4 years.

Where and why does oil appear in the filter pipe?

“Stories” happen to the air purification filter pipes that are more “interesting” than mechanical damage to integrity, but are the result of malfunctions of other vehicle systems. We are talking about the appearance of oil inside the air duct between the filter and the engine. It enters it through a breather (tube) connected to the crankcase and serves to drain crankcase gases into the pipe. When all car systems are working properly, only gases enter the pipe. If something is wrong, then oil vapors are added to the latter, which settle in the form of a liquid or thick viscous consistency on the walls of the air duct.

In fact, there is only one reason for the appearance of oil in the air filter pipe - increased crankcase gas pressure (more than that provided for normal engine operation). But this phenomenon, in turn, may be the result of one or more different malfunctions or improper operation of the car, for example:

the oil level in the engine crankcase is higher than the maximum permissible;
dirty air filter;
the crankcase ventilation system (channel) does not work (clogged);
the exhaust system is clogged (for example, the catalyst has melted);
compression rings are stuck on the pistons;
destruction of piston partitions;
destruction or wear of the cylinder-piston group.

The fact is that the functioning of the intake and exhaust systems (gasoline, air, exhaust) are interconnected and are designed for a certain resistance (pressure). And therefore, as soon as one of the links in this general chain fails, it will immediately “come out” in another place. The gas pressure increased in the crankcase - the air filter pipe became covered with an oil film.

Replacing heater cables on a VAZ 2114

Sometimes situations occur when, for one reason or another, the product becomes bent or even breaks off. Such cases require removing the device and replacing it with a new one. Recommendations for analysis are as follows:

The metal clips that hold the cable in place must be disconnected.
One end of the cable is connected to the tap, the other side to the lever for adjusting the air temperature in the cabin. Any sequence of disconnection can be followed. But it will be most convenient to first disconnect the end from the stove tap, unfasten all the clips and, last of all, disconnect it from the lever.
Now the product should be carefully removed from the case.
When reinstalling the new part, start by attaching it to the tap.

There are a lot of different models on the auto goods market that differ in length, thickness, various types, and shapes of both ends. In order not to make a mistake when purchasing a new product, we advise you to take it with you to the store. Usually cables are sold in one set of several pieces at once.

So we learned how to change the heater cables on a VAZ 2114. The most important thing when carrying out work is not to rush, to understand the principle of operation of the hot and cold air supply mechanism. We wish you warm heaters!)

Where is the heater valve located inside the car? It is located at the very bottom of the dashboard, the easiest way to get to it is from the passenger seat.

Replacement

Replacement
Now all that remains is to install a new set of pipes and complete this job. For this:

Carry out installation by following the reverse sequence of disassembly and dismantling;
Be sure to put new O-rings in place;
Fill the cooling system with coolant;
Start the engine and make sure there are no coolant leaks.

As you can see, replacing the cooling system pipes can easily be done with your own hands. This will require accuracy, consistency of your actions, as well as the use of new, high-quality parts to replace the old ones.

If you cannot or do not want to deal with such issues yourself, contact a good car service center, where they can quickly and efficiently bring your cooling system to normal condition.

It was said above that one of the reasons for the appearance of antifreeze in the car interior may be leakage from the heater radiator.

Below you will learn how to replace a leaking heater radiator. First of all, of course, you need to drain the antifreeze. Then you get comfortable in the cabin and begin to disassemble the front panel: glove compartment, consoles, sides. Unscrew all the screws and screws. To avoid losing them, collect them on a magnet or in a small plastic cup. There is one hidden screw under the plug on the dashboard console, so be careful.

When you remove all the panels and access to the heater radiator opens, loosen the clamps on the pipes, release them, but do not forget to place a mug or other container under the hoses so as not to flood the interior with antifreeze residue. Now you have to remove the VAZ 2114 stove, or rather, the heating radiator.

Assembly is done exactly the opposite. Install the new radiator in place. Experienced drivers recommend lubricating the fittings with soap to make the rubber pipes easier to put on. It is recommended to install new clamps for them, purchasing them together with the radiator. Also install the panel, glove compartment and other parts in reverse order.

When mounting the panel, be sure to ensure that the center pillars are attached to the body. Install and secure the cables, check their adjustment, make sure that the valve and faucet are functioning properly

When pouring antifreeze, check that no air pockets form. To do this, remove one of the hoses leading to the throttle valve and release the air. Reattach the hose to its place.

Don't forget about the air lock when replacing antifreeze

If you did everything correctly, there will be no more antifreeze leaks, and the cabin will become warm and comfortable.

If owners of classics quite often complain about malfunctions of the interior heater, then the VAZ-2114 stove in this regard works quite stably, coping “well” with its immediate responsibilities. If the interior is in good condition, even in severe frost, the stove will be able to provide a comfortable temperature, and ice on the windshield will be removed within a few minutes.

Cleaning or replacing the radiator

The radiator, located in the front of the car, absorbs the main flow of dust and dirt. For its effective operation, timely prevention and cleaning is necessary. The radiator can become dirty both inside and outside.

An indicator of internal cleanliness is the condition of the coolant. Manufacturers recommend changing antifreeze every 75,000 km or every 5 years. However, a change in the color of the liquid, severe darkening, discoloration, or the presence of rust requires urgent replacement of the coolant. It is recommended to change antifreeze at least every 40,000 km.

To carry out internal cleaning of the cooling system of VAZ 2110, 2114, 2115, it is necessary to drain the liquid. Sequencing:

open the expansion tank cap;
place a container to drain the antifreeze;
Unscrew the drain plug from the cylinder block;
drain the refrigerant;
unscrew the radiator drain plug (located at the lowest point);
drain the remaining antifreeze (antifreeze);
tighten all the plugs.

To clean, pour distilled water into the system and start the engine for about 20 minutes. Ordinary water contains many impurities and forms scale, so its use is undesirable. The liquid is drained several times until clean water flows out. This method is ineffective as it removes a small amount of deposits.

For more effective washing, it is advisable to use special chemical additives. The detergent components included in their composition allow you to dissolve deposits and remove various types of contaminants. The mixture of water and vinegar used by many motorists is less effective. It does not remove all deposits. After using chemicals, the cooling system is washed with distillate.

After cleaning the entire SOD of the VAZ 2110, 2114, 2115, an additional internal flushing of the radiator is carried out. To do this, you need to detach the hoses from the base and the upper and upper tank. Liquid is poured into the radiator through the upper pipe using a garden hose. Flushing is carried out until clean water flows from the lower pipe.

The removed radiator can be externally cleaned to remove dirt, insects, and sand from the cooler honeycomb. Cleaning is carried out with a soap solution or special devices that create a strong flow of water or air, for example a Karcher vacuum cleaner. The procedure should be carried out carefully so as not to bend the radiator honeycombs.

If damaged or heavily soiled, the radiator should be replaced.

Replacing the thermostat

If the thermostat valve does not operate correctly, the coolant does not circulate throughout the large circle of the ODS. The lower pipe remains cold even after the refrigerant is heated to 90°C. The top pipe may be hot due to steam escaping. The thermostat can also get stuck in the open position; in this case, the engine does not warm up to the required temperature or takes too long to warm up.

In preparation for replacing the device, it is necessary to drain the fluid from the system and remove the air filter. Then the radiator and fluid pump hoses are disconnected from the thermostat housing. After this, loosen the mounting bolts and remove the thermostat cover. The device is replaced with a working one. Attaching the thermostat is done in the reverse order.

These are the main reasons for the malfunction of the cooling system and the cold lower pipe of VAZ 2110, 2114, 2115 cars.

Sometimes, even experienced motorists wonder: why is the lower pipe on the VAZ 2114 cold? It is impossible to answer this question unequivocally; there are many reasons that lead to disturbances in the engine cooling system. One thing is clear: it is necessary to find out the cause of the breakdown and restore the system to avoid problems with the engine. Let's try to thoroughly understand everything.

Main causes of malfunction

There can be several reasons for such problems, but the most common are:

Worn or damaged pipes.
Incorrect connection of pipes.
Broken stove tap.
Radiator failure.

The first of these reasons - wear of pipes - can occur for natural reasons during operation, since the chemicals contained in coolants have a corrosive effect, which is complemented by the influence of high temperature.

In addition, the hoses of the VAZ 2114 stove can be easily damaged by over-tightening the clamps on them. When such damage occurs, fluid leaks from the system.

In total, VAZ 2114 cars have 4 pipes. Two of them are located under the hood and two in the cabin.

Their damage, which led to a coolant leak, can be judged by the following indirect signs:

there is a constant drop in the liquid level;
a specific smell appeared in the cabin;
A puddle of coolant forms under the car or in the passenger compartment while parked.

If at least one of these signs is observed, then urgent diagnostics of the pipes should be carried out and their replacement.

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.

Buying pipes from hand or on unverified Internet bulletin boards can result in untimely breakdown or bursting of the installed pipes, which in turn will make it impossible to cool the engine while running; the consequences can be the most dire. You should purchase original parts or analogues through trusted sellers; if there are none nearby, modern technologies allow you to find the necessary pipes and place an order via the Internet. The main sellers of spare parts for VAZ cars are stores such as Lada-Detal (lada-original.ru - original parts), zaphastivaz.ru (analogues and original), Exit (exist.ru original and analogues), lada-autodetal.ru and others online stores. Before purchasing online, you need to check the store’s reviews and legal details of the store.

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.
