Repair of VAZ 2114 stove: radiator (heater) and other components

With the arrival of winter, car enthusiasts often encounter problems with the operation of their heating stove. The VAZ 2114 model is no exception.

The cause of the breakdown can be any part or component of the car's heating element. You can repair the heater yourself, without using the services of a car service, so first you need to understand the principle of operation of the heating system on a VAZ 2114 car.

The heater tap is used to regulate the air supply to the cabin. It is used to regulate the supply of coolant to the heater radiator. The liquid heats up to 95 degrees and heats the air to an elevated temperature, which already enters the cabin. When the heater is on, the heater fan runs, which “drives” air into the cabin.

Stove design and diagram

The heating system for the interior of a VAZ 2114 car, both with an injector and a carburetor, is a heater that is connected to the engine. The coolant is coolant, which heats up as it passes through the power unit. The heater's task is to distribute the resulting heat evenly throughout the cabin.

Heater diagram VAZ 2114

After passing through the engine cooling system, the heated antifreeze enters the heater radiator. A fan blows on a hot radiator. Thus, warm air enters the car interior. With the help of deflectors and dampers, the direction and intensity of the air flow is regulated. The stove on the VAZ 2114 can operate in several heating modes.

Main causes of malfunction

Like any device, the stove can break.

The stove on the VAZ 2114 is characterized by the following malfunctions:

1. Leaking air ducts. Heat loss is possible at the joints of the air ducts.
2. Radiator leak. If there is a hole in it, it should be replaced.
3. Air may stop blowing if the radiator is clogged. In this case, it needs to be cleaned.

New and old radiators

• The air may stop blowing if some air duct hose is clogged. Leaves, grass and other debris can get caught in it. After removing debris, the stove pipes should allow air to pass well.
• The heater does not turn on; the heater motor may be faulty. The motor failure is due to a faulty fuse. The repair consists of replacing the blown fuse with a new one.

If the VAZ 2114 heater does not work, then the cause of the problem may be in the wires through which there is weak contact, as well as in the resistor.

In what cases is it necessary to replace the motor?

The obvious reason for replacement, as already mentioned, would be a complete failure of operation. You should also think about the need for replacement in cases where the fan makes non-specific noise, for example, it squeals a lot. This may be a consequence of broken blades or defects in the structure itself. Also, often the cause of failure of the stove fan is a banal blockage - this can be understood by the unpleasant smell and excess noise (creaks or rustling inside the unit).

A problem with a fan should be clearly diagnosed, since in one case it may be associated with a direct breakdown of the unit, and in another - with problems with other engineering systems of the car. As a rule, people often confuse a problem with the power supply and a problem with the motor itself. First of all, it is necessary to check the functionality of the electrical circuits and the integrity of the fuses, and then proceed to the direct disassembly of the stove assembly.

Repair work

Knowing the structure of the stove, it is easy to repair. Before starting repairs, it is necessary to remove the wire from ground and drain the coolant.

Repair consists of the following steps:

1. First you need to remove the instrument panel and carefully disconnect the air pipe through which air enters the cabin.
2. Next, you should check the electrical system: resistor wires, electric motor, fan. In addition, you need to check the outlet and inlet hoses of the faucet.
3. Next, you should unscrew the two nuts from the shield that secure the faucet.
4. Then you need to remove the seal from the tap pipes.
5. Next, the nuts are unscrewed, with which the stove is attached to the body.
6. Now you can remove the stove.
7. Having completed the necessary repairs and adjustments, the heater is reinstalled in the reverse order.

After repairs, you should check the operation of the heating system. It should turn on as soon as the engine starts.

Replacement instructions

The radiator is a replaceable unit, so if it is faulty, it needs to be replaced.

The replacement procedure consists of the following steps:

1. First of all, you need to drain the coolant.
2. Next you need to dismantle the dashboard. You can remove not the entire tidy, but only part of it to get to the radiator. How to remove the panel is described in the operating instructions.
3. Before replacing, it is necessary to disconnect all wires and hoses that go to the radiator.
4. Then you need to unscrew the fasteners and dismantle the unit.
5. The removed radiator must be cleaned if it is clogged. If it leaks, it needs to be changed. Assembly should be carried out in the reverse order (video author - VChSLV).

After the repair, the microclimate in the cabin will be restored and no frost will be scary.

How to remove and replace the heater valve

The price for replacing a stove faucet at a service center will be about 1000-1500 rubles, so despite the complexity of the procedure, many try to remove and change it themselves. In addition, it is much easier and faster than doing repairs. To completely replace a VAZ 2114 heating tap, a simple set of tools is sufficient, in particular:

• Wrenches of different sizes (socket wrenches, open-end wrenches for “10” and “13”), and if it’s a head with a cardan, that’s great.
• Worm clamp with a diameter of 16-23 mm
• Silicone sealant.
• Rags.
• Screwdriver with Phillips bit.
• New heating tap.
• We also recommend that you immediately buy two pipes going from the heater tap to the radiator (since they lose their elasticity over time and can leak).
• A container where you will need to drain the coolant.
• Well, if possible, use a fresh coolant itself, so as not to pour the old one back in.

And besides the tool, it is advisable to have an inspection hole or overpass at your disposal, since the tap is unscrewed from the engine compartment, and an assistant is needed from inside the cabin.

Basic aspects of tuning

Car tuning is not only about illuminating the dashboard with LEDs. Tuning the VAZ 2114 stove is required in situations where cold air blows from the sides of the stove, or the interior is heated unevenly.

To do this, you need to remove the side cover on the gas pedal side. The clamps holding the throttle cable should be loosened. Then you need to pull it back and tighten the clamp. Next, you should install the damper control levers. From this moment on, warm side air should blow, warming the driver and passengers in the cabin.

Heating system repair

At the second stage of tuning, it is necessary to ensure that air coming from outside passes through the heater. The operation of the damper and the tap is carried out by the operation of one engine. It should be ensured that it does not control the damper. To do this, the right cover of the torpedo is removed, and then the one located on the right is disconnected and pulled from the two temperature control cables from the engine. The damper should be in its maximum position. The cable should be tightened and the excess should be trimmed.

Video “Reconstruction of the VAZ heating system”

This video explains how to make the cabin warmer and therefore more comfortable (the author of the video is Alex ZW).

Owners of domestic vehicles, for example, such as the VAZ 2114, periodically encounter a problem that appears in winter - the heater stops functioning properly. Problems may result in the fact that warm air stops coming from the stove or the motorist will not be able to turn on the heating unit at all. Therefore, in such a situation, when the windshield of a vehicle is covered with a layer of dense ice “blanket”, which obstructs normal visibility, the motorist must know how to act correctly at such a moment. In view of this, if problems arise with the heater, you must first understand the structure of the system and know the circuit diagram of the unit, which will help find the cause of the malfunction.

Solving problems with a faulty stove, unit design

If a motorist wants to deal directly with the heater design, he should know what the VAZ-2114 stove diagram looks like. For active operation of the heater, only a few important parts are needed, in particular a ventilation engine, an additional resistance resistor and a toggle switch through which you can switch the speed of the unit.

Due to the fact that the motorist is faced with a system malfunction, he must first diagnose the performance of the heating device by setting the switch to the first position, then gradually move it to the second and third speed modes. Using the lever you can adjust the direction of the air flow, while the last position will help regulate the choice of air temperature.

Therefore, if the unit does not respond to the actions of the car owner, most likely the fan has stopped functioning properly. Apparently it just stopped turning on. However, if the heatsink still shows itself at least at some speeds, the problem may be related to the additional resistor. In such a situation, it would not be superfluous to check the VAZ-2114 stove, in which the switch may be inactive.

In the event that the car owner does not know how the heater on the VAZ-2114 works, and the heater fan operates at full power, while the temperature switch is set to maximum (the car’s power unit is also well warmed up), and only cold air flows from the heater, you will have to deal with the stove radiator, which, in all likelihood, is very clogged.

How to prevent the problem

The main reason for the failure of the stove fan itself is poor quality assembly. You should not skimp on such parts, and if a problem does occur, it is better to buy a high-quality unit with a manufacturer’s warranty. Such units are designed to operate under a wide temperature difference, but some manufacturers do not pay attention to quality and release stoves onto the market with a very low coefficient of resistance to temperature changes. We advise you not to skimp on this car part and purchase truly reliable components from trusted suppliers.

The device of the stove on a VAZ-2114 car

The connection diagram for the VAZ-2114 stove should be known to absolutely everyone who has come to the conclusion that the heater needs to be replaced. In order to do everything as correctly as possible, you should not forget about the need to disconnect the ground wire, otherwise the battery will not tolerate such treatment. At the same time, it is imperative to drain the antifreeze from the cooling system of the power unit.

The design of the VAZ-2114 heater is such that to replace the structure, you will have to dismantle the dashboard along with the lining of the floor covering tunnel. After this, it will be necessary, with extreme caution, to disconnect the air duct through which a warm air flow is supplied to the cabin.

In order for the heating to start functioning properly, the motorist must perform similar manipulations with the electrical wires that are connected to the resistor, the electric power unit of the fan, as well as two faucet hoses (with inlet and outlet).

After this, you need to remove both nuts that secure the faucet to the front panel. Removing the seal, which is located on the faucet tubes, will allow you to carefully remove the four nuts securing the heating unit to the car body.

If a motorist understands the structure of the stove in a VAZ-2114 car, he will be able to carefully remove the old heating device and install a new unit in the vacant space in the opposite order to its dismantling. It is important to remember that at the end of the procedure everything needs to be checked and adjusted.

Heating system modification

One of the controversial decisions is to move the heating tap under the hood and replace it with a regular household one. Before you dare to use this know-how, you should weigh the pros and cons. One of the advantages of this action is that you do not have to worry about leakage into the cabin . In general, the service life of the parts increases, but in order to open and close the tap, you need to run to the hood or reach into your feet and turn the valve. Or in the summer, drive with the air flow damper closed.

And yet, perhaps you are one of those for whom this will be the optimal solution that will help you not bother with repairing the stove tap. For clarity of removal and upgrading, watch the video instructions:

How to remove the heater valve VAZ

Replacing the tap with a water tap and moving it under the hood

As you can see, despite the certain efforts required to repair or replace the valve of the VAZ 2114 stove, it is still better to do this before the interior is flooded with antifreeze. At the moment, heating taps are presented on the markets in three main types: standard, ball and ceramic. But in fact, of all those available, there are no normal ones that you can install once and forget about the problem. Plastic ones etch, ceramics melt and run, the ball one is also not without its drawbacks, but is still more reliable compared to others. Remember that preventative repairs of parts of your car, in particular the heater valve, can prevent other, significant problems.

To optimize vehicle production and reduce their cost, AvtoVAZ uses the same components for models of different families. An example of such an assembly is the stove of the VAZ-2114 car, which belongs to the Samara-2 family. When designing this car, the interior heating system was borrowed from the models of the first Samara family - VAZ-2108-21099.

The VAZ-2114 stove is integrated, with heat intake from the engine cooling system and forced air circulation. Structurally, the interior heater of this car is simple, which has a positive effect on the reliability of the system.

Heating system VAZ-2114

The VAZ-2114 interior heater consists of the following elements:

Heating of the air supplied to the cabin is carried out by passing the air flow through the honeycombs of a heat exchanger - a radiator, through which coolant heated by the engine circulates.

The VAZ-2114 heater has the ability to shut off the supply of antifreeze to the heater radiator, so the heating system is turned off (for the summer period). The supply is stopped using a tap embedded in the coolant supply pipe to the heater radiator.

The radiator is installed in the heater housing. In addition to housing the component elements of the stove, the housing prevents the dispersion of air flow and directs its movement.

The heater body is connected to air ducts, with the help of which it supplies heated air flow to the areas of the windshield and side windows, to the middle of the cabin, to the feet of the driver and front passenger. To adjust the direction of air flow, deflectors are installed at the ends of the air ducts that supply heat to the side windows and into the middle of the cabin.

The distribution of air flow across zones is ensured by dampers installed in the housing. The design of the VAZ 21-14 stove uses three dampers:

1. Stove control damper. It redirects the air flow through the radiator (the stove is operating) or bypassing it (the system is operating in interior ventilation mode).
2. Damper for supplying flow to the windshield area.
3. Damper for redirecting warm air to the footwell area or to the side windows and into the passenger compartment.

Thanks to the dampers and the heater tap, the driver activates the interior heating system, controls the air flow, choosing which zone it should be supplied to.

The fan included in the heater design creates an air flow. Thanks to the power supply circuit of the fan electric motor being equipped with rheostats, the unit received three operating modes in which the fan rotates at different speeds.

Unlike the heating systems of cars of the classic family - VAZ-2101-2107, the fan in the VAZ-2114 forces air into the heater body, rather than drawing it in, which increases the efficiency of air supply. Therefore, this unit was installed not inside the housing, but on it. Access to the fan has become easier, since on the VAZ-2114 it is located in the engine compartment, in a niche near the engine shield.

Stove control

The control of the flaps and valve on the VAZ-2114 remains mechanical and remote, just like on the VAZ-2109. The heater control unit on this car consists of three sliders (lever) and a knob for selecting the fan operating mode. The sliders are connected via cables to the stove tap and dampers. To control the heater, the driver moves the sliders, acting on the dampers and tap.

The control mechanism for the VAZ-2114 stove is implemented in an interesting way:

1. The lower slider is connected by cables simultaneously to the tap and the main valve. When moved to the extreme left position, the valve opens, and the damper provides hot air into the cabin through the radiator - the stove operates in heating mode. By moving the slider to the extreme right position, the driver closes the tap, and the damper directs air bypassing the radiator - the heating system operates in interior ventilation mode.
2. The upper left slider is responsible for directing air to the footwell area or through the air ducts for heating the side windows and supplying heat to the cabin (central deflector).
3. The upper right slider is connected by a cable to the air supply flap to the windshield area.

Applicability

Reasons for decreased performance

Despite the simplicity of the design, problems with the VAZ-2114 stove often arise. They are mainly associated with a drop in the performance of the heating system - the stove heats the air poorly, blows cold or slightly warm air. In this case, the reasons for poor operation of the stove can be both general (warming up is weak at any control unit settings) and when operating in a certain mode, for example, at idle. Or, for example, cold air or slightly warm air blows only on the side windows, and in other modes the heating works normally.

Common reasons why the stove stops heating:

• the heater radiator is clogged or an air lock has formed in it;
• when switched to heating mode, the heater damper does not fit tightly to the body, which is why part of the air flow moves bypassing the radiator and enters the cabin cold;
• the tap does not open completely - this is one of the main reasons for a poorly heating stove;
• the formation of cracks at the joints of the housing and air ducts, which causes strong dispersion of the air flow.

It is not difficult to determine the cause of a general decrease in the efficiency of the heating system. To find out why the VAZ-2114 stove does not heat well, you need to remove the side decorative panels from the center console, and then warm up the engine and turn on the stove at maximum power. After this, we try the antifreeze supply pipe to the heater radiator up to the tap and behind it. The same heating temperature of the tube on both sides indicates that the tap is working properly and the problem lies in the radiator. If after the tap the pipe is less warmed up, the tap is jammed or does not open completely.

After this, we determine the temperature at the inlet and outlet pipes of the radiator. If the heat exchanger is not clogged and there is no plug in it, then the temperature of the outlet pipe will be lower than the inlet pipe. But if the outlet tube is cold, antifreeze does not circulate through the radiator, which indicates the formation of an air lock (airing) or clogging.

A common cause of failure of the VAZ-2114 stove is wear and play in the sliders. Because of this, even when they are moved to their extreme positions, the cables do not bring the valve and dampers to the stop (the valve remains closed, and the dampers do not block the air flow channels). This problem can be easily resolved - you need to make an adjustment and shorten the cables a little.

The problem of insufficient heating of one of the zones is associated with a violation of the damper control. This happens due to the same wear on the sliders, the cable jumping off the damper levers, the damper axes jumping out of the seats in the body, which is accompanied by clicks.

In addition to weak warming up, VAZ-2114 car owners are faced with the fact that the intensity of air flow decreases. This happens due to the dispersion of air through the cracks at the junction of the body and air ducts, clogging the latter with debris - many owners do not install cabin filters, so leaves get into the air ducts and interfere with air movement.

Heater maintenance

To ensure that the VAZ-2114 heater heats well in winter, carry out maintenance of the heater before the cold weather:

1. Remove it from the car.
2. Disassemble and clean.
3. Check the functionality of the dampers, seal their ends with sealants.
4. Seal the joints with sealant.
5. Flush the radiator.
6. After assembly, adjust the drive cables so that when moving the sliders, the valves and the tap become in their extreme positions.

These measures are enough for the heating system to function normally in winter, providing warmth to the car interior.

Finally, we note that the reasons for the poor operation of the stove were discussed above, but it still continues to function. But this unit also has breakdowns and then the stove fails and stops working completely. Such reasons include breakdown of the radiator, leaks at the joints of the pipes, fan malfunction (open circuit, exhausted motor life or burnout).
