With the onset of cold weather, each car owner performs a prophylactic inspection of the vehicle and eliminates possible malfunctions. As a rule, antifreeze, oils are replaced, tires change to winter. The stove also requires special attention, because it is one of the main assemblies of the car that ensures comfort in the cold time.

VAZ 2107 Heater Stove Device

Like any knot in the car, the stove can also stop functioning. In winter, such a breakdown can do the operation of the car impossible: the glasses are covered with frost or sweat, resulting in a worse.

To independently repair the stove, you need to know its device.

The heating system includes such components:

• Heater His task is to heat the air. The main element of the heater is the radiator, by means of which circulates the coolant.
• A fan that sends heated air into the cabin. The fan is attached to the casing by elastic pillows that quit vibration.
• The stove control system where the fan button is included, as well as the damper and control knob of heating.

Heater stove VAZ 2107, principle of operation

The heating system is functioning as follows:

In the aircraft box, which is in the engine compartment near the windshield, the air goes through special grilles on the hood.

In the case of shower or rain water, separated from the air, flows into the holes that are in the box. This makes it possible to use the heater to any weather, but until the radiator is heated, the air falling into the salon during the rain will be raw.

The air flow rushes into the heater and, passing through the radiator, heats up. Heating is adjustable using a crane that regulates the number of undergoing coats. Crane control is performed by flexible thrust that is attached to the control lever.

When moving, the flow of air enters the hood and the air itself enters the heater. When stopping or a small ride speed, an electric fan is applied, which is controlled by a switcher with three positions: "Small speed", "full speed" and "off". The reduced speed is provided by turning on the electric motor through the resistor, which reduces the voltage on the motor winding.

After the radiator, the air enters the air bodies, and it comes out by deflectors that allow the flow direction to be changed.

Stove in the car, the causes of bad work stove

Major malfunctions of the car heating system:

1. Dirty radiator
2. Leak crane, radiator, nozzles or connections between them.
3. The switch of the switch operating modes of the electric fan.
4. The wires of the device were damaged or their connections were oxidized.
5. The electric fan broke.

How to improve the work of the stove VAZ 2107 Increasing hot air

As you know, the stove on the VAZ 2107 warms well, and it works noisily. Therefore, it is not rarely upgraded. Tips for improving this device on the Internet set. Many motorists tried to independently improve the work of the heater. But the proper effect did not work.

For example, you can independently:

• redistribute air flows;
• complete the joints of the ducts with nozzles.

However, in general, the temperature in the cabin will remain at the same level. So that in the car it is cozy and heat, it is necessary to increase the amount of heat supplied using the radiator. The problem is the factory fan of the heater, which is too small and does not create the required airflow. Therefore, you need to replace the fan. At the same time, it is better to perform its replacement for a similar product from the domestic "eight", since such fans have a higher rotational speed and low energy consumption.

How to replace the fan to more powerful (detail)

Order of work:

1. Remove the lower part of the stove - the casing on which the usual fan is attached.
2. Fully remove the standard electric fan, as it does not need anymore.
3. Carefully cut one of the aerodynamic comb feeding the air to the feet of the passenger and the driver, since the motor from the "eight" is much longer.
4. Next is removed the impeller, and all the functions fall on the standard five-pointed fan.
   
5. The hole in the impeller needs to be slightly increased in diameter and gently shove the new shaft into it. Watch that the new design reliably stood in its place.
6. Before mounting a new fan, connect it directly and check its performance.
7. Replace the built-in resistor, the main task of which is to ensure relatively quiet operation of the fan. As a result of a large amount of distilted air, a new fan will create strong noise. The best replacement option will be a resistor installed on the "eight".
8. Replace the fan switch to similar from the model 2108. Cause - With a long operation of the heater, a completely different current will be supplied, due to which a long time, a regular switching button is simply melted.

Tools, fixtures, consumables

To replace the heater radiator, you will need:

1. Set of end and horn keys.
2. Crosshead screwdriver.

How to replace the heater radiator VAZ 2107 (step by step)

Order of work:

1. Loosen the fastening clamps of the heater hoses that are in the engine compartment.
2. Next, remove the hoses from the radiator nozzles. In this case, an insignificant leakage of antifreeze is possible.
3. Unscrew the screws that fix the rubber seal.
4. Remove the seal.
5. Unscrew the tape recorder panel.
6. Disconnect the cable from the heater crane.
   
7. Remove fan housing brackets.
8. Release down the casing.
9. Remove the stove radiator.
10. Install a new radiator.
11. The assembly is performed in the reverse order.

How to replace the VAZ heater crane 2107

Order of work:

1. First, it is necessary to break the clamps on the heater hoses.
2. Next, remove the hoses from the nozzles.
3. Unscrew the two screws that lock the seal, and dismantle it.
4. Remove the glove box.
5. Lost on the bracket of the air vent the nut for ten, which will allow you to dismantle the latches on the heater housing and remove the right air component.
6. Free the cable and delete it.
   
7. Remove the two nuts fixing the stove tap, and dismantle it.
8. The assembly is performed in the reverse order.
