Close the tap on the VAZ 2109 stove

Yuri, on the driver’s side, you put your head into the pedals and put your hand past the gas pedal under the panel along the floor, there is a lever on which a wire is put. Georgy, so you carefully move this lever with your fingers, at the same time feel with dry fingers to see if there are any drops of antifreeze hanging under the lever.

Anton, there are these levers on the panel... where the heater turns on... and it’s located under the panel on the glove compartment side

Pavel, what’s easier, look where the hoses from the engine go to the passenger compartment and they go to the engine shield and are put on the tap Sergey, one through pipe, the second with a valve, here the cable goes to it and adjust it, but in general, I threw it out at one time when the first 08 went in 1985 and everything was in short supply; I threw out the faucet by pushing the tube into a pipe with a damper; there was no difference in the operation of the stove; what is a faucet and what is not

Replacing the VAZ 2114 heater valve - step by step...

VAZ 2109 (low panel). where is the heater valve...

The faucet is located just above the passenger foot area, and closer to the central tunnel, on the shield separating the passenger compartment and the engine compartment.

Car owners of VAZ cars know how often they have problems with their heater taps. Especially if the car is not new. The faucet may stop closing completely or opening (jammed, jammed). Or it may leak. If the first one can somehow be overcome, then the leak needs to be eliminated as soon as possible, otherwise new problems will arise for you.

First of all, this is fraught with the risk of coolant escaping into the interior of the car, as a result of which you will be provided with a wet carpet and an unpleasant odor in the cabin. To be fair, it must be said that the leak can come not only directly from the tap, but also from the hoses and from the heater radiator. These car parts are also subject to severe wear and tear during vehicle operation.

Let's look at the types of cranes and their differences

A standard faucet installed from the factory is called "factory". Its advantage is, of course, the price. Disadvantages: unreliable and prone to jamming.

A ceramic valve costs more than a factory valve, is more durable, but has a lower throughput compared to a ball valve. Precisely because of the worst bandwidth The stove will not heat well in winter.

There is also a more reliable ball valve. But it is also susceptible to souring, and its price is slightly higher.

The heater valve is on the passenger side under the console. To replace it, first unscrew the screws that hold the right trim of the center console. There is no need to unscrew the instrument panel.

If you have not changed the cooling fluid, it is advisable to do so. Most likely, its service life has expired. Consequently, it (antifreeze, antifreeze) has lost its qualities, which can lead to engine overheating in summer and freezing in winter. Well, we won’t tell you how to drain antifreeze on a VAZ 2109. I hope this procedure will not be difficult for you.

Instructions for replacing the heater tap

  • Unscrew the plugs on the engine block and drain the coolant.
  • We clean the studs on the tap with a metal brush to remove rust. To easily unscrew the nuts from the studs, lubricate them with WD40 or Autounisma.
  • Unscrew the clamps on the hose and remove them. Don’t forget to place a container to collect any liquid that still remains in the system pipes.

It's no secret that such unpleasant moments as car repairs are not uncommon. One good thing is that large components and parts are not prone to breakdown so often.

But not a single car owner could avoid minor repairs.

Sometimes there is a problem with the heating stove faucet. When that very moment has arrived, the owner of a VAZ 2109 will understand immediately. A coolant leak will not go unnoticed. The car interior will fill with an unpleasant odor and the floor covering will get wet. Another faucet breakdown is associated with the inability to switch off the air supply. It is clear that replacement is inevitable.

Device car heater not as difficult as it might seem at first glance. The base consists of two plastic casings connected by brackets. They have a heating radiator installed. Air is supplied through the radiator to the car interior by a fan.

Heater device

The electric motor is attached to the fan casings. The coolant passes through the heater core thanks to a pump. A faucet is also connected to the cooling system. Its connection occurs through rubber hoses. There are two more pairs of pipes in the housing. The faucet valve has a hole through which coolant flows. A special valve lever controls air heating. Three knobs on the instrument panel control the heater. With their help, taps and stoves are opened or closed. If the tap is open, heated coolant circulates in the heating system. Closed - blowing cold air.

What breaks?

People usually think about heating with the first cold snap. And when the heating lever is moved to the “red” position, it can get damp under your feet. It was the coolant leaking. The reason is a rupture of the faucet diaphragm.

Naturally, there is no point in repairing. It’s easier to change it. Replacing the old element with new element heating is not a labor-intensive and quickly completed job.

Self-replacement

Like most renovations, this procedure held on an overpass.

Replacement requires the following tools:

  • Container for draining coolant;
  • Classic set of wrenches and screwdrivers;
  • Sealant;
  • WD – 40;
  • New faucet with a set of rubber gaskets.

Operating procedure:

  1. 1. Display the VAZ 2109 car;
  2. 2. Place the prepared empty container under the motor and, opening drainer, allow the coolant to drain;
  3. 3. Next, you need to unscrew the pipes running from the engine to the heater. To do this, just loosen the fastening clamps. It happens that they do not give in, then it makes sense to use a “bucket” and clean the threads of the crane bolts;
  4. 4. Remove the pipes and drain the remaining antifreeze;
  5. 5. Remove the side trim of the dashboard in the car interior. Here, too, unscrew the pipes;
  6. 6. Then, using a 10mm wrench, loosen and unscrew the faucet fastening nuts. It's under the car. Continue working inside the car again and tighten the tap on the passenger seat side. Then remove the clamp. Disconnect the control cable;
  7. 7. The next stage is the installation of a new tap. First of all, it must be connected to the control cable. Now put the spring clip in place. Tighten the fasteners. When installing pipes, use sealant.

After finishing the installation new part heater, you need to pour coolant into the system and check how the replacement went as a whole.

Modernization of the VAZ 2109 heater

Those who like to “tinker” with cars and experiment can carry out a small modernization of the crane in the old “old-fashioned” way. This will require a ball valve with an angled handle.

  1. The sequence of actions will be as follows:
  2. 1. Drain the coolant;
  3. 2. Unscrew the plug in the tap and pull out the valve. It won't be useful anymore.
  4. 3. A 3-kopeck USSR coin will be suitable as a new plug. It will need to be inserted into the “glass”;
  5. 4. Screw in the plug;
  6. 5. Under the hood, cut off the heater pipe and install a water tap;
  7. 6. Tighten the clamps on both sides;
  8. 7. Pour in antifreeze;

8. Check the system. Every car enthusiast has the right to decide what suits him best. Experienced VAZ 2109 owners recommend a ceramic faucet from Yavva for replacement. Full set represents the part itself, fasteners, sealing rubber bands

. Situations of leakage or “sticking” do not occur after installation and during operation. It makes sense to purchase new pipes. It is likely that during use they have lost their elasticity and cracked. And this is one of the reasons for coolant leakage.

The heater valve in VAZ-2114 cars is one of the weakest points of the cooling system. It breaks down so often that most car owners, having gained experience, replace it with a new one without any problems. Why it fails, as well as how to replace the VAZ-2114 heater tap step by step, we will talk in this article.

This element is a shut-off device designed to control the flow of coolant through the heating radiator. In the hot season, when the heater, as a rule, is not used, the driver turns off the tap, and hot antifreeze or antifreeze bypasses it, without heating the forced or freely circulating air in the cabin. In cold weather, on the contrary, the device opens, clearing the way for coolant to the “stove”. This is how the climate in the VAZ-2114 interior is regulated in this simple way.

The crane is activated by a cable from a control lever located on the center console of the car. This lever is indicated by a long red arrow at the bottom.

Causes of failure

There are only two reasons for crane failure:

  • sticking (souring) of the working parts of the locking mechanism to the body or to each other;
  • violation of the seal of the housing (leakage).

Considering that its design is non-removable, in any of these cases it will require not just repairs, but complete replacement heater valve VAZ-2114.

How to determine if a faucet is broken

Diagnosing a breakdown is easy. In the first case, its cause is oxidation of the elements of the locking mechanism. This leads to the fact that it simply stops moving in any direction.

When you try to move the crane control lever, it will not budge. Trying to break the mechanism by using force is fraught with breaking the lever, breaking the cable, or mechanical damage the crane itself.

Violation of the tightness of the device causes failure of the seals, which for the most part are made of ordinary rubber, which reacts with both antifreeze and antifreeze. A puddle of coolant on your foot mat will help you understand that the faucet is leaking. front passenger or oily white coating on windshield, which is its evaporation. But in this case, you will need to make sure that it is the faucet that is leaking, and not the heater radiator itself or the pipe.

Choosing a faucet

Today, you can purchase three types of heater locking devices in auto stores:

  • standard (regular standard faucet from VAZ) with a metal locking mechanism and a rubber membrane;
  • ball (with a locking mechanism in the form of a movable ball with a hole);
  • ceramic (has a locking mechanism of 2 ceramic plates).

None of the auto mechanics will recommend that you install a standard crane. It will not last long, and the price is not much different from modernized models. Replacing the VAZ-2114 heater valve with a ball valve will allow it to work a little longer, but will not completely solve the problem, since its locking mechanism is also metal.

Ceramic devices have proven themselves best. They have a plastic case and a ceramic mechanism that is not susceptible to oxidation processes. Such a device will work for a long time if the seals do not fail.

Below is a table of heater valve models for VAZ-2114 vehicles, indicating the manufacturer, catalog number and type of locking mechanism.

What should be on hand

To ensure that replacing the VAZ-2114 heater tap does not take much time, it is better to prepare in advance necessary tools and funds. We will need:


In addition, the car will need to be installed on a “pit” or on an overpass.

Preparing for the replacement process

Having driven the car onto the overpass, open the hood and unscrew the plug filler neck radiator and plug expansion tank. Next we go under the car. At the bottom of the cylinder block we find a coolant drain plug (do not confuse it with the oil drain plug on the crankcase). Having first substituted an empty container, unscrew it with a 13 key and wait until all the liquid has drained.

After that, we get out from under the car and head to the engine compartment. Replacing the heater tap will be done from inside the cabin, but first we will need to unscrew it from under the hood. IN engine compartment On the passenger side we find two pipes going into the cabin. These are the inlet and outlet pipes of the faucet. Loosen the clamps on them and disconnect them. Next to the pipes there are two studs with threads and nuts. They, in fact, fix the tap. To make it easier to unscrew the nuts, we treat the studs with anti-rust liquid.

For convenience, when replacing a faucet, some craftsmen and car owners completely disassemble the instrument panel. It is not necessary to do this at all. We will tell you how to replace the VAZ-2114 heater tap without removing the panel.

Crane dismantling

We move into the car interior to the front passenger seat. There is a panel cover to the left of the passenger's feet. It must be removed by unscrewing the screws with a Phillips screwdriver. Now that we have access to the heater radiator cap and tap, we place a dry rag under them. It is needed in case of coolant leakage.

Using a screwdriver with a cross-shaped bit, loosen the clamps of the pipes on the locking device and disconnect them.

Next, replacing the heater valve requires disconnecting the drive cable. We take pliers and, holding the rod bracket with them, use a flat screwdriver to disconnect the drive cable. After this, we move again to the engine compartment.

Using a 10mm wrench, unscrew the nuts securing the faucet. Next, remove the broken locking device on the front passenger side.

Installing a new heater tap

Installation of the tap is carried out in the reverse order. First, we attach it to the body by tightening the nuts on the studs, and then connect the drive cable. It is also better to replace the clamps on the pipes with new ones. Pay attention to the condition of the hoses. If their ends are too stretched or cracked, it is better to replace them too. If everything is in order with them, we connect them to the tap and tighten the clamps with a screwdriver. We don’t put the panel cover back in place yet. We will need to check the tightness of the connections with the engine running.

That's basically the whole process. As you can see, replacing a VAZ-2114 heater tap with your own hands is not such a difficult task.

Completion of work and checking for leaks

Upon completion of the work, we return under the car and tighten drain plug. After this, pour coolant into the radiator neck, focusing on its level in the expansion tank.

Replacing the VAZ-2114 heater valve requires a thorough check of the tightness of the connections upon completion. repair work, and the master himself will be interested to know how well he worked.

We start the engine and warm it up until the radiator fan turns on. Without turning off the engine, we check for leaks at the connection points of the pipes in the cabin and under the hood. If everything is fine, we try to close and open the tap by moving the control lever with the heater fan on. In the open position, the air forced into the cabin should be hot. This means that the shut-off mechanism is open and coolant is flowing through the radiator. When you close the tap, cold air should flow in. This will indicate that the locking mechanism has blocked the flow of coolant into the heater radiator.

  1. The VAZ-2114 heater tap should be replaced as soon as possible when faults are detected. Especially when it comes to coolant leaks. Both antifreeze and antifreeze are toxic!
  2. You should not save money when choosing a faucet. It is better to take a good branded model that does not oxidize and use it for 5 years than to buy a device of dubious quality and origin every year.
  3. Do not use cheap coolants - the duration of operation of not only the faucet, but also the entire cooling system depends on their composition.
  4. If the faucet is leaking and there is a smell of antifreeze or antifreeze in the cabin, and there is an oily coating on the glass, take the time to wash and dry the rugs or carpet, and also wipe the glass with an alcohol solution.
  5. If the process described above seems complicated to you, it is better to contact a car service.

Replacing the tap in the heater of a VAZ 2109 cannot always solve the problem of heating the interior, like its brothers - models 2108 and 21099. The system responsible for heat in these cars has many similarities, so let’s look at the problems and troubleshooting using their example.

What is hidden under the panel in the car interior?

The “refrigerator effect” becomes most noticeable if you still continue to use old VAZ models with front-wheel drive: 2108, 2109, 21099. Let’s try to figure out if there is any possibility of replacing them yourself heating system. Despite the visual identity of the car models, there is still some difference in these VAZ units of the 8th and 9th models.

This difference is not fundamental. It’s just that in the process of evolution, unnecessary air ducts were removed from the design, the shape of the damper and the location of the radiator were changed. But this does not change the principle of operation. The interior is heated by air, a radiator connected to the engine cooling system is responsible for heating it, and the heater itself is located under the instrument panel in the car, which is higher in the VAZ 21099 due to some design features of the stove. With the help of connected air ducts, heat flows into the interior.

To force heated air into the cabin, a fan is located at the top of the heater, which rotates using an electric motor. The easiest way to access it is from the engine compartment. , which was mentioned above, is located in the VAZ 2109, 2108 and 21099 models near the heater itself. It has a seal in the form of a polyurethane foam gasket and consists of two plastic tanks, cooling plates and tubes arranged in two rows.

Since heating is connected to the car’s cooling system, fluid circulation through the radiator occurs using the pump of this system. You can regulate its flow using the heater tap and various levers that affect the position of valves and dampers. To the salon warm air It enters through two central and two side nozzles, inside of which there are dampers that regulate the heating intensity. The direction of flow is also changed by blades-blinds using levers in the cabin.

After the air in the cabin is heated, it is necessary to circulate it and maintain the set temperature. It is necessary to release the waste stream outside. In this regard, on VAZ 2108 models hot air comes out through holes located in the central body pillars. On 9-model cars, these holes are located in the corners of the rear side windows and have rubber valves that prevent atmospheric air from entering the air ducts.

Bringing the radiator to life

As a rule, it is not the entire system that becomes unusable, but only some part of it. The first signs that it is necessary to intervene are a specific smell in the cabin, the appearance of steam from the exhaust vents, and very rapid evaporation of coolant. First of all, you need to check the radiator. You should not bother with checks when the engine is running or has not yet cooled down.. The problem most often lies in the radiator, in the area of ​​the heater tap or in the electrical circuit. Let's consider these weak spots more details.

Replacing a faucet or electric motor is not the first step; first you need to carefully inspect the radiator for leaks. Then you will have to remove it and check the tightness. The radiator is removed in the following order. First you need to disconnect and (preferably) remove the car battery, completely drain the antifreeze from the cooling system and disconnect the wires from the sensor that turns on the fan motor. Then you will have to remove the fan casing fasteners, disconnect its bracket and wires, and tilt it to the side. So you can get protective cover. All that remains is to disconnect all the hoses, slightly tilt the radiator to the side and remove it out.

It should be noted that it would not be superfluous to replace the rubber shock absorbers located on the radiator holders.

After the unit is removed, it is necessary to put tight plugs on the pipes or holes (except one) to which they are connected. Through the remaining inlet it is necessary to pump air into the radiator. Just be careful: do not allow air pressure to exceed 0.2 MPa. After this, lower the radiator into a bath of water, preferably so that it completely covers it. If air bubbles appear, the seal is broken and replacement is necessary. If there are no bubbles, there is a chance that it is simply clogged. In this case, it is necessary to flush the device.

Replacing the faucet and fan motor – can we do it ourselves?

If checking the radiator does not fix the problem, the cause is in the heater itself. The next common breakdown is. But even in this case, you will have to remove the entire device, since it is unlikely that it will be possible to determine the nature of the problem, and, most likely, only a replacement can help. First you need to disconnect the hoses from the pipes on the heater tap, unscrew the faucet fastenings and remove it. Then you should dismantle the rods going to this part, remove the facing panel on the floor and disconnect the air duct located in the tunnel. Next, all that remains is to remove the heater wires, unscrew the mounting nuts and remove the device. Naturally, replacement and installation are done in the reverse order.

Of course, it is advisable to carry out all the operations described above for the first time under the guidance of an experienced comrade (if there is one, of course). Because it is very easy to miss some little thing in the circulation of pipes and nuts, therefore it will not be easy to find an error. By the way, if your friend is a good specialist in the field of heating systems, he will probably be able to give advice on how to get rid of the old-fashioned way of saving a car radiator by wrapping it in cotton vests or cardboard boxes. The fact is that the VAZ 2108 and 9 models have a drawback in the heating operation when the engine is cooled too much. And such an unusual radiator lining can, on the contrary, lead to overheating.

A more rational approach: an additional pipe is cut into the thermostat housing and at the same time a plug is placed on the opening of the water pump. Thanks to this engineering solution, the liquid from the heater flows to the thermostat, and then continues to move through its cycle. The thermostat will be part automatic system cooling, and you won’t have to remember about engine overheating in summer and excessive cooling in winter. This method has received a patent, and therefore such “tuning” can be officially ordered at a car service center if you decide to entrust the replacement of the system to him.

The motor in the heater, which is responsible for circulating heated air (via fans), can also break down. Replacing it is easier than repairing it, so you just need to buy the right one. Installation will not be difficult, since we have already disassembled the entire system according to the above instructions.
