Where is the tap of the Priora stove 16 valves located?

Many vehicle owners begin to think about how efficiently the heater in a car works only in the cold season, when driving in a car that is not warmed up due to a broken heating device becomes simply uncomfortable and unsafe. It cannot be said that problems with the heating device occur only in certain brands, however, most often those drivers who have a used vehicle such as the Lada Priora encounter such a malfunction. There are situations when the stove refuses to work at all or begins to function not as it should. In the material below we will consider the principle of replacing the heater tap in a Lada Priora car.

As you know, in the winter season, the operation of a car’s heater largely determines driving comfort. But sometimes it happens that the device simply refuses to work, and this problem especially often occurs in domestic cars. Read more about how to replace the heater radiator on a Lada Priora car below.

Priora heater

Copying of material is permitted only with a link to the source. There is only one reason - the stove does not heat well. The LADA Priora interior heating system performs a number of functions: it heats, cools, and ventilates the interior; in this article we will look at the heater design separately. Key words: heater control unit Priors heater fan Priors air ducts Priors interior temperature sensor Priors heater damper gear motor Priors heater Priors heater radiator Priors Priora heater resistor.

Hello, in this article you will learn how to replace the heater valve on a VAZ. The first sign of this is a puddle of antifreeze under the front passenger's rug. Of course, a puddle can still form from a leak in the heater radiator; here you need to look at what exactly is leaking. The best way to fix a leaking heater tap is to replace it with a new one. The heater valve is also removed when replacing the heater radiator. The average price of a heater valve in the automotive market is about rubles, in some places it may even be less.

Heating device design, common breakdowns

If for some reason a motorist decides to change the heater tap on a Priora, he must first understand the air conditioning system of the domestic vehicle, which will allow him to find out the true reason why the unit does not function properly (stopped blowing). In a situation where the heater begins to supply extremely cold air into the cabin, and the car does not have air conditioning, the owner of the movable property must check several important design details. As a rule, first of all, you should pay attention to such elements as the control regulator, fan and stove faucet.

To exclude the possibility of breakage of other parts and to look for the place where the Priora stove faucet is located, you will have to inspect the fan. The functioning of which, in particular the number of revolutions, depends on the temperature inside the car. The difference between warm and cold flow depends on the operation of the valve. As for the air that is supplied directly to the vehicle itself, it necessarily passes through the filter element, thanks to which everything is cleaned. Only after this the driver of the car can choose the direction of the airflow by adjusting the position of the dampers, manipulating the installation using the central console.

For example, if you suspect a fan is not working, you should find out about the functionality of its contacts. Sometimes, when the latter are oxidized, it is not a complete replacement of the device that helps, but just cleaning the connector. In the event that the device operates exclusively in the maximum position, the resistor responsible for the rotation speed should be checked.

A problem with the stove in a Lada Priora car may occur due to a failure of electrical components, in particular due to fuse F9, which, if faulty, must be completely replaced.

Priora heater

Lada Priora is a product of the domestic automobile industry. This car has earned people's love for its low cost, good quality, and the availability of parts when repairs are needed.

Despite good reviews from owners, the car is not without a number of shortcomings. For example, it happens that the Priora stove only works at speed 4. You can go to a service station to find out why the Priora stove switch is not working.

But you can wait for your turn for several days, and the problem needs to be solved as quickly as possible. If you are familiar with the device of the tenth model, then you can easily figure out the heating system on the Priora.

There may be several reasons why the temperature of the Priora stove is not regulated. Let's look at what these reasons are:. Before you begin troubleshooting the heating of the furnace, it is necessary to eliminate the impact of breakdowns of the cooling system and engine. Only then can you begin to figure out why the stove mode switch on the Priora does not work.

To do this, we check the antifreeze level and engine operation. First step: look into the expansion tank and determine the coolant level. Then turn on the engine and warm it up for a while. This will allow you to determine whether the thermostat is functioning correctly. If you find that the top pipe is hot, this indicates that the device is functioning normally. A cold pipe is a sign that the thermostat is not working properly and you will need to replace it.

This part is inexpensive, so replacement will be easy. A loose expansion tank cap is another reason why the engine remains cold. Because of this, the Priora stove switch may not work. The cooling system of Lada Priora is slightly different from the tenth model; it practically does not create an air lock. It can be caused by incomplete system insulation or antifreeze poured into an empty expansion tank.

Solving the problem is not difficult. Remove the reservoir cap, stand on a hill with your front wheels and accelerate. Often the heater regulator on a Priora does not work due to the fact that a large amount of dust or other small dirt particles has entered the heat exchanger. Over time, contaminants get inside heating devices.

This cannot but affect the performance of the entire system. Air masses do not warm up well. You may note that the oven only works in position 4. In case of contamination, you can simply replace the entire radiator. You need to remove the device from the power unit side. Do not forget to first drain the antifreeze from the cooling system, disconnect the windshield wipers and wires, dismantle the fan completely and remove the entire radiator by removing the pipes leading to it.

There is not only the problem that the Priora stove operates only at maximum, but also the complete absence of air jets from the heating system. The first step is to make sure that the radiator is working in principle. Place your hand and note whether any streams of air are blown out. Even cold air masses indicate that the system is operating. If the fuse stops, it means the furnace fan is broken.

One possible reason for the fan not spinning could be small leaves or other small objects that have gotten into the fan. This will be confirmed by a hum. If necessary, you can remove the fan on the Lada Priora using the same procedure as on the tenth model.

Replacing the fan will solve the problem. A breakdown of the gearmotor on a Lada Priora can lead to the damper not operating, which will prevent hot air jets from entering the cabin.

You can get to the gearmotor through the hood. If the problem is not with the damper, then most likely the stove is not working due to the contacts being oxidized. Simply clean them with sandpaper. Often, replacing the filter can help solve the problem of weak air mass flows - when dirty, it becomes an obstacle to the passage of warm air. And then, even at high speed, the air flow can be too weak.

You can also repair the rheostat of a Priora stove with air conditioning yourself. It is enough to replace the thermal fuse. This is precisely what a clogged filter affects. The thermal fuse overheats and fails; it only works at the maximum position. If the Priora stove only works in position 4, then this may indicate that the rheostat has burned out. The same problem can lead to the heating system operating exclusively in the first position.

Additional resistance causes the stove to work worse and slower. You will note that the Priora stove switch does not work. Many passenger cars of the domestic automobile industry have a similar resistor block to the Lada Priora.

Repair and replacement of heating faucet

If, in fact, it turns out that the stove on the Priora has stopped functioning as it should due to an inoperative faucet, the car owner will have to replace the failed structural element. To do this, consider a detailed and very accessible step-by-step plan for replacing the above part.

As for the necessary tools, the motorist will only need a 10mm socket and a wrench. After everything is ready, you should begin to implement the idea, initially ridding the cooling system of the power unit of the antifreeze contained in it.

Then it is necessary to dismantle the glove boxes on the Priora, in addition to removing the luggage rack. Only after carrying out all the steps described above, even an amateur motorist will be able to independently replace the heater tap.

The next step is to loosen the clamps that secure the heating system hoses. It should be noted that all these parts are located directly in the engine compartment. The motorist will have to disconnect the hoses and pipes of the heater tap. Before starting this process, it is important to mark the location of the pipes to be removed. In exactly the same way, you should disconnect the hoses that come from the heater tap in the car interior.

Having completed these steps, the novice mechanic will see the area where the Priora stove faucet is located and will be able to independently unscrew both nuts responsible for fastening the structural element being replaced. Then you can begin to remove the heater tap, while working on the cable tension. It is imperative to remove the bracket and remove the cable that is connected to the crane lever. Only these actions will help you remove and change the tap of the heating device. At this stage, we can consider that half of the actions are over. All that remains is to get rid of the rubber seals and install the new stove faucet back in the reverse order of its removal.

Complete replacement of the heater gearmotor

If a motorist wants to replace a faulty gear motor of a heating device, he should start by removing the beard from the dashboard and also removing the pedal assembly. Such manipulations will not allow you to completely get rid of the torpedo. After this, you can carefully remove all the screws that secure the unit. All this will help get rid of the necessary device.

The car owner, having removed the previous heater gear motor, will be able to use a plastic device to replace the non-working device with a new one.

However, to get rid of the problem, you should first call someone you know. In fact, it is quite difficult to cope with such a problem alone; the help of a friend will make the process easier and faster.

Factory heater damper gearmotor

Replacing a damper gearmotor on a Priora requires first of all connecting the contacts to a new device

It is very important to position the unit in such a way that the holes of all screws are in their proper places. The next step is to use an assistant to influence the temperature regulator, simultaneously pressing on it

If all the squares match, we can happily talk about the success of the procedure. As a rule, this will ensure a normal supply of air at the temperature that will be set by the motorist.

Installing and turning a new gear motor

The problem can be corrected by further screwing in the screws, as well as by rotating a new gearmotor. The unit should be checked gradually moving from the blue mark to the red mark, moving the handle in the opposite direction

It is important to do this so that the car’s heating system can fix its operating range, in the future functioning as required by the owner of the Priora

Priora stove tap where it is located with air conditioning

For the sake of the experiment, I installed the heater valve to check whether the temperature in the interior would drop when blowing cold air from the heater, because it is no secret that the switch between cold and hot air on the Prior is done by means of a damper, i.e. hot air constantly circulates through the heater radiator. and. and even if the damper is completely sealed, the interior will be heated by infrared radiation from the heater radiator, no matter how insignificant such heating would be. Naturally, I didn’t take any temperature measurements, but according to subjective sensations, the air began to flow a little cooler. Plus, I redid the connection diagram for the heater radiator by connecting the expansion tank hose with the radiator return hose, but this modification for winter is more detailed here

Purpose of the heating gear motor on the Lada Priora

A gearmotor is a device consisting of several plastic gears driven by a small electric motor. The main task of the gearmotor is to open and close the heater damper depending on the position of the regulator on the dashboard.

Geared motors on Priora are made only in plastic, non-separable housings

The plastic from which the gears are made deteriorates quite quickly. After which the driver is forced to change the gearbox. This device cannot be repaired, because, firstly, it is not possible to find spare parts for it, and secondly, it is not so easy to open the plastic housing of the gearbox without breaking it. So there is only one option left: replacement.

Gearmotor location

The gearmotor on the Lada Priora is located near the expansion tank, under the windshield.

The gearmotor on the Priora is located under the windshield near the expansion tank

It is built into a niche on the wall of the engine compartment and covered with a thick layer of sound-insulating material. This material will have to be removed, since otherwise it will not be possible to get to the gearmotor.

Signs and causes of gear motor failure

There are two signs of a gearmotor failure on a Priora. Here they are:

when starting the heater, a loud grinding or knocking noise is heard from under the dashboard, which becomes louder as the heating fan speed increases;
inability to adjust the oven temperature. The heater blows either only hot air or only cold air. The position of the temperature regulator on the dashboard does not matter in this case.

All of the above happens for very specific reasons. Here are the most common of them:

one or more teeth on one of the gear motor gears has broken. The tooth fragments rotate together with the damaged gear and hit the plastic housing of the gearbox from the inside. As a result, a characteristic dull rattle or knock occurs, which is clearly audible in the cabin;

Car heating system malfunctions

In a Lada Priora car, the heater regulator does not work due to a malfunction of the multi-position switch or a defect in the blower fan. When troubleshooting this problem, when the Priora stove fan does not work, you should look at the fuse box, which is the main source of trouble for the operation of the ventilation device. Many defects in a car's climate system are directly related to the operation of the vehicle's cooling system.

If the fan device is in good working order, but the stove on the Priora does not heat well, then the defect should be looked for by a sequential method of cutting off the tested elements. So, the stove on the Priora is not working well and the interior is quite cool:

Replacement: how to remove (change) the stove on a Priora with and without air conditioning

Replacing a stove completely is rarely done; components are mostly changed. Often the main reason for disassembling the heater on a Priora car is replacing the heater radiator. When it ceases to be airtight and no longer works as efficiently, it is necessary to begin repairs. In order to remove the heater on a Priora car without air conditioning, you will need a set of wrenches (socket and socket wrenches) and a Phillips screwdriver. As the system is disassembled, it is worth inspecting all parts and replacing worn ones. Perform the work according to the instructions:

Remove the negative from the battery.
Remove the lower windshield seals and engine sound insulation.
Loosen the clamps that hold the pipes adjacent to the heater core, and then disconnect them. First place a basin under the pipes to drain the coolant. After the liquid has poured out, cover the pipes with a rag.
Start wiring. Unclip the latch and disconnect the motor wires. Then de-energize the additional resistor.
The wires that go to the damper drive motor are secured with a clamp. You need to bite it and then disconnect the wire.
Next, we proceed to dismantling the heater itself. Take a “ten” socket wrench, remove three screws with it, and remove another screw with an “8” wrench.
Next, move the wiring harness from the heater to the side (attached to a small bracket).
Now, from the passenger compartment under the dashboard, unscrew the third nuts securing the brake pedal with the “13” key, and then move it to the side.
Pull the block towards you.
Install a new heater instead of the old one if necessary.
When you are concerned that the heating is not blowing correctly - not in the required mode - you will have to check everything again during dismantling.
To remove the heater on a car with air conditioning, follow these steps:
Also remove the negative terminal, then the lower windshield seal, and the engine sound insulation.
Unscrew the screws covering the heater radiator.
Also carefully remove the pipes: the coolant must be drained into a prepared basin.
Slowly and smoothly pull the radiator up until it comes out of the mounts.
Install the new radiator in the reverse order.

Lada Priora has Panasonic or Halla air conditioners. They differ only in the fastening, so there will be no difficulties when replacing the heater radiator.

Malfunctions

For normal operation, the heating system needs: tightness, integrity of parts and normal antifreeze. The first step is to check the relay and fuse - after all, this unit contains electrical appliances inside. If the unit's electrical network is not in contact with the ECU, there is no point in turning the controls on the heater control unit.

The heater fuse on Priora has the number F9. In order to get to it, you need to remove the plastic plug above the driver's left knee (under the headlight switch) by unscrewing three bolts around its perimeter.

Once the fuse has been inspected and no deficiencies have been identified, further diagnostics can begin.

While driving a VAZ-2170, you should carefully look and listen to what you see and feel. If heat should come from the cracks, but it doesn’t, then something is wrong with the seal or the damper gear motor. For example, if the glass becomes greasy, as if it was smeared with your hands, it means that the heater radiator is leaking. However, these are not the only signs of a heater failure.

Priora: the stove blows cold air, does not heat - reasons

When cold air comes from the heating system and turns into the air conditioner, the following possible malfunctions are considered:

The heater hoses do not supply coolant, or the radiator itself is not efficient enough and does not take heat from them.
The air filter is dirty. If there is no new part nearby, try removing the filter and then starting the heating system without it.
The damper gear motor is stuck.
The control unit (switches) is broken.
The temperature sensor in the cabin has broken (it is located under the roof).

The shutter does not move, and the modes: face, legs, glass do not work

Reasons for this problem include:

Faulty air distribution gearmotor.
Inoperative control controller (CU).

It’s noisy – what to watch

When you hear an unknown noise, you need to check the heater motor bearing. The noise is caused not so much by the bearing, but by small debris that has gotten under the motor blade.

The stove does not blow and does not even turn on

There are only two reasons why air does not escape from the heating system of a Lada Priora car. When the interior heating does not work, you need to check fuse F9 and the switches on the center console - perhaps they are simply broken.

Replacing the heating gear motor on a Lada Priora

First of all, it should be said that replacing the gearmotor on a Priora with and without air conditioning is done in the same way, since the gearbox is located quite far from this device. It should also be noted that today there are several known ways to remove the gearmotor from a Priora. One of them involves removing only the trapezoid along with the wipers and expansion tank, the second allows you to get by with removing only the tank. But to use these methods, the driver must have extensive experience in self-repair, otherwise problems are inevitable. Therefore, the third method will be discussed below, with the complete removal of all necessary parts. Yes, it will take more time from the car owner, but it is almost impossible to break anything. Now it's time to decide on the tools. Here's what we need:

new gear motor for Priora;
2 screwdrivers - flat and Phillips.

Replacing the Lada Priora heater valve (VAZ Priora)

Often Russian car enthusiasts who drive a Lada Priora complain that the heater is not working well, the vehicle interior is cool, and the car’s side and windshield windows are freezing. In order to understand why the stove on the Priora stopped working, let’s look at the design of the entire heating system on cars of this modification.

Priora interior heating system

The vehicle is equipped with a stove (heating system) with a climate control system that provides comfort while traveling in the car. They are designed to eliminate problems in the event of cold weather or other weather changes. No one will ask the question why the stove in the Priora does not work, neither the driver nor the passengers.

Important points

There are a couple of nuances, without mentioning which this article would be incomplete:

The old gearbox should be removed very carefully. A long shank sticks out of it. If you remove the gearbox at an angle, you can damage the edge of the hole for the shank. If this happens, installing a new gearbox will not be so easy. Therefore, advice: when removing the gearbox, it should be pulled in a plane parallel to the floor;
When buying a new gearbox at a car dealership, you should only buy the original VAZ one. Yes, its quality leaves much to be desired. But this is still better than buying a fake gearmotor, which the spare parts market is literally flooded with now. You can spot a fake by price. A normal gearmotor on a Priora costs 700 rubles and more. And a fake rarely costs more than 300 rubles.

The principle of operation of the stove - what it consists of on Priora, article numbers

For the VAZ-2170 restyling, two types of heaters were installed - with a Panasonic control controller or with an NSS control controller. The last type contains the following parts:

air recirculation damper gearmotor (21700-8127300-10);
Priora car heater fan (motor) (21700-8118020-10);
air filter (21700-8122090-00);
motor speed controller (2170-38127025-10);
heating system damper motor (21700-8127200-10);
heater radiator (21700-8101060-10);
outlet hose (21700-8101208-00);
outlet pipe (21700-8101200-10).

As for the second option from Panasonic, the device around the radiator of the heating system on the Priora is slightly different:

recirculation valve (21700-811908-00);
fan (stove motor) (21700-8118020-10; 21700-8118020-00);
vacuum hoses with check valve (21700-8119100-00);
solenoid valve (21700-8119130-00);
air filter (21700-8122020-00);
inlet pipe (21700-8101200-00);
damper gear motor (21700-8127200-00);
radiator temperature sensor (21700-8101250-00);
radiator (21700-8101060-00);
outlet hose (21700-810120800).

The pre-restyling car has a lot of parts from the “tens” - even the gearmotors are different. Much was inherited from the VAZ-2110, and the first cars before restyling were almost completely equipped with its heater. The assembled stove for the VAZ-2170 Priora pre-styling received catalog number 2111-8101012-10, a more updated version – 2170-81010-12. Price from 5500 rubles.

Changing the cabin filter

There are Lada Priora configurations that include air conditioning. It could be HALLA or Panasonic. Owners of such cars are also concerned about replacing the stove on a Priora with air conditioning. But first, it’s worth understanding the air conditioners themselves, which differ not only in the country of manufacture.

HALLA is made in Korea and Panasonic is made in Taiwan. You can find out which air conditioner is installed in your car by visual inspection.

Attention should be paid to the button, which is located in the center of the air conditioner control panel. Panasonic system has a button to turn on, but HALLA does not have such a button

Car owners should regularly change the filter to ensure that the cabin is free of foreign odors from the street and the air is clean. Before you find out how to change the heater filter on a Priora, you need to know the type of system that is installed in your vehicle. After all, each cooling system model has different filter elements.

The filter changes differently depending on whether the car has air conditioning or not. If the car is not equipped with an air conditioning mechanism, then proceed as follows:

Open the hood.
We dismantle the grill installed under the glass on the left. There are screws on it, closed with plugs. They need to be unscrewed. After completing this step, access to the filter will be freed.
The cleaning component cover is held in place by four bolts that must be removed.
We remove the cover, which will allow us to get the filter. We clean the vacated area from possible contamination and debris.
We install a new filter element and assemble the car in the reverse order.

If the car has a cooling mechanism, the actions will be slightly different.

Open the hood and find the required part.
We bend the upholstery material.
If Panasonic is installed, then the latch on the filter element must be unscrewed. With a Hull cooler, you will need to press the latch, which will open the lid.
We take out a filter that has already served its purpose and in its place we put a new one, which will need to be twisted using the slots in the housing.
We install the cover and all parts in their place.

Repairing the Priora stove may be associated with a number of problems that initially need to be correctly diagnosed. We will write several more articles on this topic and consider the main problems in detail. In any case, you need to know how to disassemble the stove on a Priora, because this is the basis.
