and the rest of the "classics" models - the heater radiator is scored, and the stronger the radiator cells are clogged, the worse it will give heat.
But before you blame in all the stove radiator, you must check:
- The coolant level in the expansion tank.
- visually fluid should be slightly less than half.
- Is the cooling system not imported,
- when the engine is heated, the supply nozzle must be warm (in the figure it is indicated by the arrow).
- The performance of the stove crane.
The heater crane is located from the passenger side under the glove compartment. (The figure shows the radiator with a crane in the position shot and the arrow approximately indicates where to look for a heater crane when it is installed).
The figure shows the radiator with a crane in the position shot and an arrow indicately indicated where to look for a heater crane when it is installed - Warm the car to engine operating temperature
- We try the nozzle that throws the cooling fluid to the crane, it should be warm (so we make sure that the circulation of fluid on the system is there).
- In the ventilation control levers panel, we move the top lever until it stops the right (the heater crane is open).
- We try the pipeline that goes from the crane to the stove, just carefully that it would not write a hand, the pipeline should be warm. For confidence, we include a blowing fan, after a couple of seconds after discovery, warm air should go.
If the pipeline from the Cold crane and there is no warm air output, then there are 3 reasons:
- The cable broke through which connects the control lever and the crane,
- The cable is advantageous but closed to the casing,
- Crane trite "Zakis" and does not turn. This is very frequent cause Since traveling the warm season, and this is 5-6 months, we do not use the stove. Then we try to turn the checkbox into the open position if I do not change the memory to twist you need to counterclockwise, but if there is a new faucet, it is better to see the position openly / closed on it. As often, the crane is so zeromes that the flag from the effort of the hand begins, then remove the checkbox and try to twist the pliers.
A more couple of moments:
- Before checking the crane in order to protect your nerves and not remember the Vase constructors once again, the regiment that is under the glove compartment to remove.
- I want to say from myself that having bought the cheapest faucet then most likely have to change it before the first in winter.
If there is a circulation of fluid on the system, the level of antifreeze and the heater is normal to carry their attention to the radiator, which is located in the cabin. It needs to be removed, many are afraid of this procedure and debug work in a long box. And if you do not give God you have a radiator slightly slightly, all the liquid is going under the rugs that it is difficult to notice if it is rare to make general cleaning. As a result of high humidity for about a year, the bottom can rush literally saying "from the Nutria".

Problems and solutions
Consider the frequently found problem in the classics of VAZ 2107 2105 2106. The stove does not heat, heats badly, when working is noise. In order to deal with this problem, we removed the stove, unfortunately the shooting of this process was not made, but we will show how it will be back, who has difficulty, I think everything will understand.
Immediately deal with the noise of the stove when working, it turned out that unpleasant sound Pubs the stove radiator. Correct it with sickness it? Seal in a circle (you can use the usual for doors and windows that are sold in Hozmag). This action solves two tasks, the stove is no longer no cozy and at the same time begins to warm better. Since the slots are closed through which the air went out. As is known, the air comes out, where the resistance is less and before the sining, most of it came out through the slots, less through the cells of the radiator. As a result, the cabin in cold weather is rather cool and not comfortable.
Also, when disassembling your attention on the overall condition of the stove radiator, if necessary, clean its cells.
Video VAZ Classic 2107 2105 2106 The stove is bad:
Every year, a good motorist should think about the preparation of his car to winter. Most are limited to the change of rubber and motor oil. But checks require all systems that will operate at low air temperature. These include the stove of the VAZ 2107, which each motorist should use.
On cars up to 40-50 years old, the 20th century there was no stove, although the hot engine itself served as a prototype of the stove. A diagram at which the motor and its coolant serves as a source of heat, was recognized as the most optimal, was not implemented immediately. Despite the motor, which was a source of heat, the heating scheme sometimes included a wheel with coal under the feet of the passenger.
The car heating system can suddenly fail for many reasons, and if in the summer it is possible to close the eyes, it is winter at low temperatures and wrapped off all the windows, and the operation of the car will become dangerous, and may be impossible. It is necessary to know well and imagine the VAZ 2107 stove device so that in the cold season there were no unpleasant surprises with salon heating.
The heating circuit includes the following parts:
- Heater, main part of which is radiator 5; His task is to heat the air penetrating outside;
- The heater fan, or the motor (motor) 14, which sends heated air into the cabin, it rests in a special casing 16 on elastic pillows for vibration.
- The heater control system is a fan button, (you can use two modes of operation) 18, three heating modes control knobs;
1, 9 - pipes of air ducts heating side braids on the right and left;
2 - heating air duct windshield;
3 - radiator casing;
4 - aircraft lid;
5 - heater radiator;
6 - Crane (crane) of the heater;
7, 8 radiator hoses for removal and supply of hot liquid cooling system.
10 - swivel deflectors;
11 - duct damper;
12 - air distribution cover;
17 - control traction;
19 - Central Air Force
The principle of operation of the heating system is as follows:
- Air for heating comes outside, through the "grid" of the hood.
- In the back of the engine compartment there is a special seal made of rubber box for air flow.
- In it, the air flow is sent to the heater, separated from rainwater in the case of a shower on the street. You can use the heater during the rain, but the air in the cabin will be wet until the radiator is heated.
- Next, the air is heated by the heater, more precisely, its radiator that feeds on the liquid of the car cooling system. The degree of heating is regulated by the amount of hot fluid that adjusts the heater's tap. The heater crane is controlled by a flexible burden coming from the control lever.
- Air can passively enter the salon at high speed of the car, as it is displaced by entering podcast space Cold air, creating a zone of increased pressure, and may be carried away by turning on the heater fan. Therefore, at high speed, you can use the heating system without additional load on the power supply. This switching is carried out by clicking the fan switch having three positions - neutral and two inclusion speeds: small and increased. When tuning the cabin instead of a switch, a button can be installed. These velocities provide a resistor that increases the chain resistance and reduced impeller movement. Enjoy forced circulation Air should be at low speeds of movement, as well as when standing in traffic jams.
- Fan "drives" airflow on the system of air ducts to the parties, in side stool For the review of the rear-view mirrors, and warm air leaves the deflector lattices, which can be changed the direction for the best blowing. Also warm air leaves the air duct for blowing wind (windshield) glass.
In the figure, blue shows the circuit circulation of cold air flows, orange - the flow diagram of the heated. We list the main parts of the heating system in "Profile"
1-air distribution cover;
2 - Fan Electric Motor (Motor);
3 - Karlson, impeller housing;
4 - Heater Crane.
15 - copper shirt (radiator body);
The heater is managed:
- Changing the position of the air distribution cover of the fan casing using the lever (up-down);
- By changing the position of the arms of the control unit (air flow covers, windshield heating valve and side brake).
What malfunctions are most often found in the heating system
- Leakage of compounds (nozzles, heater crane, radiator body), which is manifested by a county;
- Malfunction of electrical equipment of the heating system (mode switch, fuse, wire oxidation, motor). The fan of the fan is in the block under the number F The fan does not consume too much energy, so the fuse is designed for the transmitted current 10 A. The following is placed below mounting block, the desired fuse of red.
The most important thing is that on this fuse are located except the impeller, the reversing lamps are located and the rear window heating. Therefore, it is not recommended for a long time to include all the consumers of energy and give reverse, for example, to get out of a snowdrift. The scheme does not provide for the presence of a relay for these chains.
One of the most common operations is to replace the heater crane.
On the VAZ 2107 can sometimes leak the puddle on the front rug on the right, to the feet of the passenger. So, the driver's faucet is faulty. They have to use quite often.
Before changing the crane, you need to purchase a set of pads for it. Replacing the crane is made under the cold engine, and then you can burn. Motor must be jamming for a half hour for comfortable work.
Sequencing:
To install a new crane you need to use new gaskets. After replacing the installation, we perform in exactly the same sequence, only on the contrary.
You need to use the new crane carefully, it is also required to add to the cooling fluid engine (more precisely in expansion tank).
It should be easily open and closed.
Check the damperDesigned for the supply of cold air, which is in the heater. A good flap should be freely closed.
When the machine works, the heater radiator must be completely hot, and not partially. Control this can be touching the oven.
In the case when the damper and the crane work impeccably, but the furnace is still not good enough until the engine turns will exceed 2000, follows evaluate circulation of oh.
The causes of poor quality circulation There may be several:
- pump - it must be checked, and if the problem is not in it, then go to the elimination of other possible problems;
- the absent pressure in the cooling system - may occur during the formation of leaks of antifreeze or antifreeze, conduct an inspection standing with a lantern, eliminate damaged hoses or clamps, and then replace them with new ones, it is also worth checking the lid on the expansion tank. This production moment very important, so requires special attention, especially the part of the design in which the thin hose from the expansion moves directly to the radiator. Leak should not reach the fan.
The main condition for ensuring the ideal circulation of the OH is a tightness due to which the required pressure and quick circulation is supported. There is a fairly simple way to check for tightness. Watch if the walls of the expansion tank are heated when the engine is running at least 10 minutes. Cold tank indicates about insufficient pressurewhich would contribute to the feed of the coolant in the oven, i.e. Turns less than 2000 are not enough powerful.
Another reason for the absence of circulation can be excess oxidewho clog the furnace. Too fast heating of the machine in the traffic jam also indicates problems with pressure, namely there is a seeping of air through some damage.
All this is verified in practice. It turns out that for the most part, with such problems, there is no need to replace the radiator, the thermostat or, as often happens, complete reconstruction dashboard To disassemble the heater.
If you sit at the computer and learn the cooling system of your car, you will immediately become clear that the lack of pressure. Therefore, just open the hood and find all damage to the hoses and lower, they can be practically invisible when the cracks occur in the hose. Thus, the first step in the case of similar problems should be the replacement of all hoses with new ones.
For the owners of the VAZ-2107, it is always unexpected. The driver learns about the existing problem with the onset of cold weather when there is a need for heating the cabin. It is impossible to say that the heating system on the seven is bad is bad, no, the manufacturer was good at her time. But still the owners are often faced with the stove not working. It is with this problem that we will understand.
How to identify the problem and eliminate it
There are several reasons why or not working at all. In this case, it is necessary to act as follows:
- Check the crane for opening.
- Whether the candle of cold air is capable of closing.
- When the car is running, check the stove (heater radiator) for heating.
Replacing the radiator
If the problem lies in the radiator and it is required to replace it, then act is necessary as follows:
- We drag the liquid.
- We unscrew two clamps from the engine compartment, which are located on radiator nozzles. Remove hoses.
- We unscrew and remove the fastener on the rubber seal.
- We dismantle the radio panel and fastening the cable on the drive of the heater crane. To perform this work, you will need the key to 7.
- Further turns on the move, with which 4 spring brackets with fan casing are removed. The casing is lowered down and shifted to the left, after which the radiator can be pulled out.
- Now you can, reanimate it or replace it with a new one. The assembly is carried out in reverse sequence and no difficulties implies.
Rubber of the radiator - a frequent cause of the non-working stove
We restore blowing glass
The stove that is installed on the VAZ-2107 has some constructive features, Because of which the left nozzle is often not well blows the glass. To put up with such inconvenience in winter - the case is difficult. Therefore, it is necessary to work on the elimination of this problem. It is necessary according to the following scheme:
- Remove the deflector from the nozzle, going on one of his sides with scolding.
- The case of the deflector is held on the torpedo with small beaches. Soad your hand inside and pull it out.
- A 50mm fan from the computer must be positioned in the center of the dismantled case and mark the mark in the appropriate places.
- In a plastic case, with the help of a stationery knife, hacksaw or acute knife, cuts are created on places of marks.
- Plastic is easily packed through the lines of the cuts and it turns out the discourse in which the fan is installed. It should be closely located in his place.
- Return the insides of the deflector in place. Internal blades will not be able to rotate for full force due to changes made.
Other minor malfunctions
Independent search and elimination of minor problems - convenient skill for any motorist
After such actions, it will be easy to determine the causes of the breakage. And they can be as follows:
- If the fauce is working properly, the stove is heated only at large engine speeds and under such conditions begins blowing warm air, the fault is to search in the pump or leakage of coolant. To find a leakage, it is necessary to carefully explore the necessary interior zone. If you find the leather, you need to replace the hoses, pull it out or install new clamps. You should not deprive the lid on the expansion tank. Tightness is the main condition at which the heater will be able to function normally.
- The leaks can also occur due to rusting of the radiator, cranes and other elements of the heating system. In this case, it is enough to simply replace the necessary part and enjoy a comfortable ride.
- Tightness can be checked for another unacceptable way. Turn on the engine and wait for 10 minutes. During this time, the expansion tank must warm up. If this did not happen, we can talk about the absence of pressure, which is necessary for feeding antifreeze or antifreeze into the heater stove.
- If you have noticed that the car is very heated when standing in traffic, then we can talk about the absence of the necessary pressure.
- And to be covered from the inside by oys of various substances. In this case, it is necessary to clean the garbage and clean the system.
The car owner must be ready for small problems and be able to quickly eliminate them. For example, with the onset of winter, many owners and to run with this problem to specialists are not always convenient.
