As a rule, car owners remember the outstanding salon stove only after the arrival of the cold. One beautiful cool morning you are trying to heat the car salon, and the heat does not go. I don't want to freeze in the car, but a hundred to go very expensive. What to do? In this case, to save your budget to help independently repairing the heating system. About this further in the article.

Heating VAZ 2110, device and principle of the stove

The car heating system of VAZ 2110 consists of: a block of electronic control of the stove, operating from the cabin, air ducts that depart from the stove, and the heater unit that provides heating of the cabin.

The heater block is represented by such elements:

1. The electric motor on which the fan is fixed to pump hot air.
2. Radiator, without which the system will not work. At the same time, in contrast to the heater of the old sample, the radiator of the new stove of VAZ 2110 does not have a crane that overlaps the flow of antifreeze (toosol) through the radiator. As a result, he is always (at least in summer, at least in winter) heated. This is done to eliminate the flows that are not rarely observed through this crane, as well as - for the maximum rapid heating of the cabin, if necessary. The supply ventilation in the summer goes past the radiator, but some car owners of the VAZ 2110 during the repair of the stove add this crane into the system.
   
3. Three dampers, one of which closes / opens the heater channel, the second is responsible for the recycling of the air intake, and the third most important for the cabin is controlled by the heater.
4. Resistor regulating the speed of blowing.

All items are enclosed in a block with additional fittings, shields and valves. All this unit is dressed in the case and is located in the pumproom space closer to the dashboard.

Ducts VAZ 2110, device and why are they needed

Air ducts provide:

1. Salon ventilation by central nozzles.
2. The air distributor is responsible for the supply of heat or ordinary air for the purpose of ventilation.
3. For heating of the legs there is a whole system that consists of five nozzles.
4. Two air ducts are directed to the back of the car salon.
5. Two side ducts are responsible for heating side windows, as well as partially salon, which provides better heating.
6. There are also 2 nozzles for ventilation.

Electronic furnace control unit

The electronic control unit includes:

1. Controller handle. This device makes it possible to set the temperature in the cabin that the stove block produces. The controller handle places the air temperature that corresponds to the one by the side, and is included by turning the handle (up to 30 degrees Celsius). This detail is usually called the Sao controller.
2. The temperature sensor controls the inclusion of the stove when the air temperature in the cabin decreases by 2 degrees against the specified one. The sensor has a michenetizer, and when the control knob is located in the position A, the micromoter is turned on in the stove block, after which the flap starts to work, which provides proper heating. Therefore, before repairing the heating system, you need to check the operation of this sensor. It is located near the heating lamp on the ceiling. Since its repair is not provided, during breakdown, this device must be replaced immediately.

Stove 2110 than a new sample furnace differs from the old oven

1. The main difference between the new stove from the stove of the old sample - in the design of the radiator. Therefore, if you decide to repair the heating system, you decide to establish a radiator of a new sample, some nuances should be taken into account.
2. In addition, the Sao controller also has certain differences. So, 4 and 5 positional controllers issued until the fall of 2003 have already been removed from production and they will not suit the new heater models.
3. Also differ microreuctors released until September 2003. The main difference is resistors, so it is necessary to pay attention to the fact that the resistor in the MMP model bought by you is interchangeed.

Causes of malfunction of the furnace

1. The temperature of the stove is not regulated. The reason you need to search in the control unit either in the flap.
2. The ceiling sensor does not work.
3. The stove does not work, only cold air comes into the salon.
4. Bad hot air to the side windows and / or to the legs.
5. The coolant level drops, which can occur as explicitly (when flowing from nozzles or radiator) and secretly.
6. The stove works, but is very noise.

If the temperature of the cause is not regulated and how to eliminate

If you adjust the temperature of the air that enters the salon, it is possible that the malfunction lies in the temperature sensor located on the ceiling, near the ceiling. To check it, turn the regulator until it stops right, after which bring hands to the air flow that comes from the heating system. If the heat goes, regardless of which position, the regulator (in the red part) is not the sensor. But if the air goes only if the controller is located in the maximum heating position, it must be replaced (or requires replacement of the regulator itself).

You also need to check the flap status. It is selected by the motor compartment - you need to remove the central deflectors and shifted by the damper with our hand. If you have to shoot it, it is better to replace the plastic, which is coming to aluminum, because it does not hang so quickly and deform.

The heater is faulty, causes and how to eliminate

If the heater "was worn out", it must be replaced. In this case, the masters recommend the following models: "2112-01" and "2112-02". They are ideal for the car VAZ 2110 and differ in that the air filter includes a complete set.

The motor destructor is faulty, how to replace the motor deuctor, step by step instruction

1. We dismantle the wipers.
2. Remove the bowl.
3. With the help of a short crosshead, we unscrew three screws that fasten the gearbox.
4. Disgust the wires.
5. We put a new motor deuctor to the place of the old, for what you should ask the helper to switch the positions of the regulator while you mount this item.
6. Install Jabs and wipers back.

Refinement of the VAZ 2110, modernization of the air flow, if hot air does badly on the side windows and legs, step by step

Such a problem is quite common on VAZ 2110 cars - the heat and legs are bad to the glasses and legs, although it goes normally from the heater.

The solution to this problem is only in the modernization of air ducts and, in addition, to eliminate the slots in the canals and the cabin. Although this work is rather complicated, if you make it qualitatively, you can forget about frozen side glasses and legs for many years. Of course, provided that the heater itself is working.

In addition, many mount the preheating heaters, which makes it possible to warm the car's interior faster.

Tips Pros: Rules for using the heater so that it serves a long time

1. Check the coolant level regularly.
2. Use only high-quality cooling fluid.
3. Keep track of the Tosla temperature sensor - do not bring the arrow on the red sector.
4. Never use water, as its boiling point is lower than that of Tosol. In addition, water leads to rapid corrosion of the cooling system elements.
