Replacing the heater tap

So, if a motorist is faced with the task of changing the heater faucet on a VAZ 2106, it is necessary to start the process by draining the antifreeze, which is in the cooling system of the power unit.
Then use a screwdriver to loosen the clamps and remove the hoses coming from the radiator pipes of the heater.

Repairing the heater tap on a VAZ-2106 requires unscrewing both screws using an “8” key, which will allow you to get rid of the seal that wraps the radiator pipes.

The following manipulations will require the driver to move into the vehicle interior, since it is there that the dashboard shelf and the glove box body itself can be removed.

To remove the old stove valve, you need to use a key set to “7” to loosen the screw as much as possible, while removing the drive rod that goes directly to the part being replaced.

Using a key set to “10” helps to unscrew both screws that hold the faulty part to the radiator. Then you should get rid of the non-working element of the system, along with it dismantling not only the inlet pipe, but also the rubber gasket.

The same device (key set to “10”) will help unscrew the screws that connect the inlet pipe valve and the gasket.

Before proceeding to the next step, you should carefully inspect the gasket profile, only then removing and replacing the bracket securing the drive rod with a new device.

The new heater element, of course, is installed in the reverse order. The motorist must fasten the part together with new gaskets and only after that fill the engine cooling system with antifreeze. At the end of the work, it is important to check the tightness of the connections located between the valve with the radiator and the inlet pipe.

What is it responsible for and where is the stove valve located?

The VAZ 2105–07 interior is heated by means of a coolant (antifreeze, antifreeze), which circulates through the cooling system of the power unit. Heat is removed from the stove radiator, which is connected to the system through two pipes. Thanks to the operation of the heater fan, air is forced through the heat exchanger, heated and supplied to the vehicle interior. However, heat is not always required. So, in the summer, sometimes you have to turn on the window defrost to prevent them from fogging up. In this case, heating will be unnecessary. To be able to regulate the supply of warm air, the heating system has a stove tap. This unit is used to regulate the supply of hot coolant (coolant) to the heater radiator or completely shut it off. As a result, the fan does not heat or heat the interior when it is not required.

The stove valve is located directly at the inlet of the radiator and is secured with two bolts. Sealing of the connection is ensured by a rubber seal. The crane is controlled by a cable with a lever on the front panel. By moving the lever, you can close or open the locking mechanism, thereby regulating the flow of fluid through the radiator and the temperature of the air that enters the cabin.

When is replacement needed and which faucet to choose?

The need to replace the heater tap arises for a number of reasons. These include:

knot jamming;
leakage;
The air in the cabin is not warm enough.

We recommend: Engine control unit: the heart of a modern power unit
It is worth considering these problems in more detail. Faucet jamming occurs due to blockage or scale formation when using water instead of antifreeze. The malfunction can be eliminated by cleaning or replacing the unit. Sometimes it happens that the control cable flies off the faucet. In this case, it is enough to return it to its place and secure it. If the valve is jammed, the control lever will move with great force. If the movement of the lever is slight, then this indicates that the cable has flown off.

The stove tap is controlled by a cable, which can sometimes fly off the lever on the tap

The most common problem with a faucet is a leak. As a result, a puddle of coolant forms under the front passenger's feet. If antifreeze is used in the cooling system, then when a leak occurs, an oily coating will form on the glass in the cabin. In this case, the coolant level in the system drops, which can lead to serious consequences - engine overheating. First you need to tighten the faucet mount to the radiator. If this does not help and the fluid leak does not stop, the unit usually needs to be replaced.

Antifreeze contains substances harmful to the human body, which indicates the need to eliminate the problem as soon as possible.

One of the types of stove faucet is a ball mechanism.
Having found out that the faucet needs to be replaced, you need to decide which part to choose. Today you can purchase a ceramic or ball locking mechanism. Therefore, owners who are faced with a choice have a question: what to choose? Based on the experience of Zhiguli owners, a ceramic part is more preferable, since ceramics are not subject to oxidation.

The ceramic heater valve is considered more reliable compared to the ball valve

As for the ball valve, it has to be changed 2 times a year - in spring and autumn. However, the choice remains with the car owner.

Replacing the heater valve on a VAZ 2106 with your own hands

The stove is one of the most popular elements of a car in cold seasons.
Agree, it’s nice to climb into a warm, cozy car interior from the wild cold. But sometimes the car’s heater works so poorly that it seems warmer outside than inside the car. In addition, without a stove you are guaranteed to have frozen windows. The malfunction of the stove must be corrected immediately after detection, otherwise you will have to wait until the spring for the car to “thaw”. One of the common causes of stove failure is a problem with the heater valve. And we will tell you how to get rid of it. Let us remind you that in the previous article we told you how to replace the clutch slave cylinder on a VAZ 2106 with your own hands.

Replacing the heater valve on a VAZ 2106

1. All coolant system fluid must be drained. 2. Loosen the clamps using a suitable screwdriver. 3. We release the hoses leading to the radiator pipes of the heater. 4. Unscrew the screws from the seal and remove it.

5. To free up working space, move the dashboard shelf. You can also get rid of the glove compartment for a while. 6. Find the drive rod of the heater valve. 7. Loosen the rod and unscrew the screws that secure the radiator and faucet. 8. Remove the inlet tube and gasket along with the tap.

9. Release the inlet pipe. 10. Place the bracket that secures the drive rod on the new tap. 11. We put new gaskets on the new faucet and do the reverse steps. 12. Fill in new coolant.

The heater valve replacement is complete. All you have to do is check the tightness of the new system and start the stove. Wait a few minutes for the liquid to heat up and travel all the way. Now your salon is warm and cozy again.

How to replace the heater tap in a VAZ-2106 car

Replacing the VAZ-2106 heater tap may be necessary suddenly when the owner of a domestic vehicle discovers a malfunction of the heating device. As a rule, most car enthusiasts encounter this problem precisely in the cold season, when it is not possible to heat the interior to a comfortable temperature. The material below discusses the principle of replacing the heater tap on a VAZ-2106 car. Acting according to the instructions, even a novice amateur mechanic can repair a faulty structural element.

Procedure for replacing the heater VAZ 2106

The vehicle interior is heated by engine coolant. The heater design details are shown in the diagram. Many car enthusiasts only think about the heating system when it gets cold. But sometimes the heater can remind you of itself with an unpleasant smell in the cabin and the appearance of puddles of antifreeze under the feet of the driver or passenger in the front seat. This means that the heater core is leaking and needs to be replaced. This work can be done with your own hands. To do this you will need:

open-end wrenches for 7 and 10;
flat and Phillips screwdriver;
Antifreeze supply is approximately 1.5 liters;

The procedure for dismantling the heater radiator on a VAZ 2106

First you need to do a number of preparatory work:

Coolant drain
Removing the heater housing with fan

Next, under the hood of the VAZ 2106, you need to unscrew the clamps on the coolant hoses that go to the radiator. This is clearly shown in the photo below:

And we remove them by applying a certain force, pulling towards ourselves:

After everything done above, we go back to the salon and unscrew the nut securing the cable on the heater faucet, this is where you will need the head 7. The faucet is located on the right side (passenger side):

You don’t even need to unscrew it all the way, as the cable will come off the faucet on its own:

Now unscrew the two radiator mounting nuts, which are clearly visible in the photo:

Now you can pull it down, as clearly demonstrated in the picture, with considerable effort:

And holding the tube, we pull the heater radiator back:

The result of the dismantling work is shown below:

If you need to replace the faucet, this is done very simply: unscrew the two nuts securing it to the radiator:

And remove it by lifting it up a little from the studs:

The price of a new one depends on the metal it is made from. Copper is expensive and costs about 1,400 rubles, but aluminum can be bought for only 600 rubles. When replacing, all procedures are carried out in reverse order.

How to replace a crane on a VAZ 2101-2107 “classic”, “Volga”, “Niva”, “Oka” (work order)

The operations for replacing the heater valve on different cars are very similar and differ mainly in the need to dismantle some parts to gain access to the failed valve.

Note: the heater faucet from the Zhiguli also fits the Volga, Niva, and Oka cars.

Next, we will consider in detail the replacement of the tap on VAZ 2101-07 “classic” cars.

According to the instructions, before proceeding with the removal of the pipes, it is necessary to drain the liquid from the engine cooling system. This operation can be omitted, given the fact that the stove radiator and pipes are located above the level of the main radiator. It should be taken into account that some of the coolant will still leak out, so you need to have a small container on hand.

Use a screwdriver to loosen the clamps and remove the hoses from the heater radiator pipes. Do not forget to place a container under the hoses to drain the coolant leaking from the pipes.

Using a key “8”, unscrew the two screws and remove the seal from the radiator pipes.

In the car interior, remove the instrument panel shelf. For convenience, remove the glove box body. On VAZ 2104, 2107 with an instrument panel with side air ducts, it is also necessary to dismantle the air duct by unscrewing the nut to “10” and prying the latches around the perimeter with a slotted screwdriver.

Using a key set to “7”, loosen the screw and disconnect the heater tap drive rod (1).

Removing the stove tap

Using a “10” wrench, unscrew the two nuts securing the valve to the heater radiator (2) and remove the heater valve along with the inlet pipe and rubber gasket.

Using a “10” wrench, unscrew the two nuts and disconnect the inlet pipe with the gasket from the tap. Pay attention to the gasket profile.

We remove and replace the drive rod mounting bracket on the new faucet.

Advice: it is better to replace “old” metal hose clamps with new reinforced ones (blue).

We install a new faucet with new gaskets in the reverse order of removal. To be on the safe side, we apply sealant to the joint surface between the faucet and the radiator, as well as the faucet and the inlet pipe.

Installing a new heater tap

We fill the engine cooling system with liquid (if it is completely drained) or add some of the liquid that leaked from the pipes and radiator during replacement, and make sure that the connection between the valve and the heater radiator and the inlet pipe is tight.

VAZ 2106 stove repair

Heating the VAZ 2106 never caused any particular problems if all elements of the heating system worked smoothly. The stove lasts a long time and requires almost no maintenance, so in winter you can always rely on it. Mechanics are mechanics, and sometimes even the most reliable and proven units malfunction, and the 2106 stove is also subject to aging.

Signs of a malfunctioning stove

It's cold in the cabin, that's all the signs. And if you go deeper and study the issue in more detail, then the first signs of a malfunction of the stove and the heating system as a whole can be considered:

antifreeze leak;
increased noise of the stove fan;
difficult adjustment of curtains and heater tap;
the blowing air temperature is not high enough.

As a rule, the stove fails suddenly, and at the most inopportune moment. Then you have to find out the reasons and eliminate them, and no matter how reliable the VAZ 2106 is, repair of the stove is inevitable.

Causes of malfunction of stove 2106

Fundamentally, the design of the stove is very simple, which is why it is reliable. The stove consists of

Heater radiator.
A fan consisting of a motor and an impeller with a casing.
Stove tap.
Distribution valve.

The stove diagram is shown in the photo, and it hardly requires any explanation. Despite its rather compact size, the stove successfully does its job, but there may be reasons, which we will discuss later on eliminating. The causes of heater malfunctions in most cases are antifreeze leakage, failure of the heater motor and failure of the heater tap.

Antifreeze leak

It is simply impossible not to see an antifreeze leak from the system, because it will literally leak under your feet. First of all, we find the place where the antifreeze is leaking and think about how to deal with this problem.

The main culprit, as a rule, is the stove radiator. Older models have copper radiators, and if that's what you have, you're in luck. It can be tinned, washed, and it will be as good as new. If the stove radiator is made of aluminum, there is little use in repairing it. If there is absolutely nothing else to do, you can try to restore it - put a patch of epoxy resin if it bursts in the area of the pipe, or try sealing it with a sealant if a leak has formed in the honeycomb. But there is no guarantee as to the result of the work, so it’s easier to change it.

Before removing the radiator, you need to make sure that it is the radiator that is leaking and not the rubber hose on the pipe. The temperature often causes the rubber to dry out and develop a barely noticeable crack, from which antifreeze leaks. Replacing the tube will solve this issue if it is not possible to trim and shorten it.

The same applies to the heater tap. The faucet itself is quite reliable in design, but the heating pipes are simply leaking. Inspect the places where it interfaces with the tap, and then you will be able to avoid dismantling the tap, although there is nothing complicated about it.

Fan motor replacement or repair

The heater fan motor has a hidden talent. After a certain mileage of the car, he begins to sing, and in exactly the kind of voice that can infuriate the stony Dzerzhinsky. It starts to make noise when the engine is not warmed up, and then calms down, but not for long. Therefore, at the first manifestation of a malfunction, it should be changed immediately.

It is better to do this when we are changing the radiator itself, so as not to disassemble the entire structure once again. As a rule, it cannot be repaired and can be thrown away with a pure heart.

The operation of the VAZ 2106 stove may be affected by the operation of the thermostat; you should pay more attention to the condition of the air ducts - they may simply become clogged with leaves. As you can see, repairing the VAZ 2106 stove is not difficult, the main thing is to know the reason, and it can always be eliminated quite simply, and then your six will always be warm. Don't freeze, and good luck on the roads!

Owners of VAZ models say that any of us will certainly encounter the problem of a ruptured heater valve diaphragm, and then the heater valve will need to be repaired.

It happens that such crane repairs have to be done in harsh winter conditions. When subzero temperatures occur, the heating switch is moved to the “red” territory, in other words, providing a constant flow of warm air to heat the interior. Sometimes in these situations a puddle of antifreeze appears under the front passenger seat.

Trouble with the heater tap.

We may encounter the same phenomenon in the spring, when we turn off the stove. Based on this, there is a joke among amateur drivers that it is recommended to touch such a gentle tap only every six months.

Temperature regulation is achieved using the damper for supplying outside air. The most economical ones, or, as people call them, “plyushkins,” have a spare set of taps in stock at any time, ready for installation.

Manufacturers have not come up with anything to replace a quickly failing diaphragm. The use of alternative cork structures does not give a positive result. There is no leak, but the tap can jam in any position and at the most inopportune moment.
