By car vaz 2106 stove stopped working. In order to fix this problem, you need to figure out what caused it.
How to find the cause of a bad oven
First of all, you need to check the pipes, if the pipe that goes from the tap to the radiator is hot, and the one that goes from the radiator to the engine is a little warm, then, accordingly, it also blows a little warm.
You can also check it in the way described below: turn off the stove motor, drive the engine, wait for the stove radiator to warm up, and turn on the stove, if the stove immediately gives out much more heat than usual, then there are problems with coolant circulation. If there was no temperature jump, then the stove gives out all the incoming heat. If there is not enough heat, then it is necessary to insulate the engine compartment.
The problem could also be in the heater core.
It is possible that a blockage has formed, or an air lock. If a traffic jam has formed, it can be eliminated very easily, for this we put the car on the curb with the right front wheel, and leave it to work for about 10 minutes, if the traffic jam is to blame, then the air will come out. In the event that, it’s not so easy to get rid of it. Needs to be cleaned. We buy a special liquid, and fill it into the cooling system. The best option would be either flushing with the heater radiator removed, or even replacing it with a new one.
It should open and close easily.
Check damper designed to supply cold air, which is located in the heater. A properly functioning damper should close freely.
When the machine is running, the heater core must be fully hot, not partially hot. You can check this by touching the oven.
In the case when the damper and faucet work flawlessly, but the oven still does not warm up well enough, until the engine speed exceeds 2000, you should evaluate coolant circulation.
Causes of poor circulation there may be several:
- pump - it needs to be checked, and if the problem is not in it, then proceed to troubleshoot other possible problems;
- lack of pressure in the cooling system - it can occur when a leak of antifreeze or antifreeze occurs, it is worth inspecting with a flashlight, eliminating damaged hoses or clamps, and then replacing them with new ones, it is also worth checking the cap on the expansion tank. This production moment is very important, therefore it requires special attention, especially that part of the structure in which the thin hose from the expansion goes directly to the radiator. The leak must not reach the fan.
The main condition for ensuring perfect coolant circulation is tightness, which maintains the required pressure and rapid circulation. There is a fairly simple way to check for leaks. Observe whether the walls of the expansion tank heat up when the engine has been running for at least 10 minutes. A cold tank indicates insufficient pressure, which would contribute to the supply of coolant to the furnace, i.e. RPMs below 2000 are not powerful enough.
Another reason for the lack of circulation can be excess oxides that clog the oven. Too fast heating of the car in a traffic jam also indicates problems with pressure, namely, there is air seepage through some kind of damage.
All this has been tested in practice. It turns out that for the most part, with such problems, there is no need to replace the radiator, thermostat, or, as is often the case, a complete reconstruction of the dashboard to disassemble the heater.
If you sit down at your computer and study your car's cooling system, you will immediately understand that the lack of pressure is to blame. So just open the hood and look for any damage to the hoses and leaks, they can be almost invisible when a crack occurs in the hose. Thus, your first step in the case of such problems should be to replace all hoses with new ones.
In the winter season, every driver wants to feel comfortable in the cabin of his car. If it is cold inside the car, then there can be no question of any comfort. Unfortunately, many domestic cars have the same weak point - their stove often fails, due to which the air temperature in the car becomes too low.
VAZ 2106 cars are no longer produced at AvtoVAZ plants. These cars are outdated, but many motorists continue to use them, and they often face the problem of poor interior heating.
Why does the VAZ 2106 stove heat poorly?
This question often arises among the owners of this model. There are many reasons why the VAZ 2106 stove starts to heat the interior poorly. However, among them there are the most common ones.
So, most often the VAZ 2106 stove starts to heat up badly due to the disturbed circulation of the coolant, which must pass through the heater radiator. This happens if the tap is jammed, because of which the antifreeze simply cannot enter the radiator. The radiator itself may also be the cause of this phenomenon - the circulation of the coolant is disturbed when the radiator is contaminated.
By the way, to determine whether the circulation of the coolant is disturbed, you can turn off the furnace motor and drive the engine a little. It is necessary to wait until the heater radiator warms up. After that, you must turn on the stove itself. If, when the stove was turned on, there was a temperature jump, that is, there was much more heat, then the problem is precisely in the circulation of the coolant.
In addition, the cause of poor interior heating may be a coolant leak, and leaks usually occur due to leaks in the radiator, which, in turn, appears due to corrosion, rust.
What to do if the VAZ 2106 stove does not heat well?
What to do if the VAZ 2106 stove does not heat well? First, of course, it is necessary to identify the cause, and then it will be necessary to eliminate it.
If the reason for the poor performance of the VAZ 2106 stove is problems with the faucet, then it can be replaced. This does not cause any special difficulties, however, it should be borne in mind that it is not easy to get to the faucet from the passenger compartment. It is also important to remember that when replacing a faucet, it must be seated on new rubber gaskets.
If the reason is the formation of a thick layer of scale that appears inside the radiator over time, then you can either try to clean this device, or purchase a new radiator. It should be borne in mind that it is very difficult to achieve complete cleaning of the radiator from scale - some of it still remains, as a result of which heat transfer deteriorates.
To clean the radiator, it is necessary to add a special additive to the antifreeze, which will remove scale. You can also completely remove the radiator and rinse it with water from a hose, while the water jet must be directed to the outlet pipe. Remember that you can not flush the radiator with high pressure water - because of this, the device may be damaged. After flushing the radiator with water, it will be necessary to remove the scale - this is done with the help of special preparations, descalers or a concentrated solution of water and vinegar. If you decide to use a decalcifier, it is best to purchase one that does not require boiling after mixing with water. The solution should be poured into the radiator and wait 30-60 minutes, and then you will have to flush the radiator with a stream of water. This procedure will have to be repeated several times.
Finally, the radiator should be washed with household detergent and thoroughly cleaned again with a jet of water. Also, instead of antiscale, you can use a solution of water and citric acid - in this case, the solution is best left in the radiator for several hours.
In the event that the cause of the poor performance of the stove is a radiator leak, then you need to find out what it is made of. The copper radiator can be repaired. If the channels of the copper radiator are clogged, you can pour acid into one end of the tube, close it with a rubber stopper and wait. This operation will clean the channel from all dirt and rust. But the aluminum radiator will have to be replaced with a new one.
The problem with the operation of the stove in the VAZ-2106 car becomes the most relevant, of course, in the winter. This is explained simply - in the summer there is simply no need for it. Meanwhile, when the weather is cold outside, the driver wants the cabin to be warm and comfortable. Naturally, this will not happen if the stove is not working. One point should be noted. Problems in the operation of the stove can be different, for example, the complete absence of air supply to the passenger compartment, or only cold air is supplied. Let's look at them in a little more detail.
If the stove does not heat up in a VAZ-2106 car - causes and their elimination
Quite often, the owner of the "six" while driving may encounter the following, very unpleasant situation. The stove is on, you can hear the fan running, but instead of warm air, for some reason, cold air enters the cabin. As soon as you notice this, stop immediately and check the coolant level. To do this, open the hood and look at the expansion tank. As a rule, the stove stops supplying warm air just because of a sharp drop in the coolant level.
If this guess turned out to be correct, the first step is to check the tightness of the connection of all hoses and pipes. In addition, inspect the radiators for possible leakage. A nuisance of this kind that has caught on the way becomes a rather serious problem, because it is very difficult to find the right pipe somewhere on the highway. Soldering a leaking radiator under such conditions is also problematic.
It is unlikely that any of the drivers takes spare pipes with them on the road. If the problem is in them, then you can temporarily eliminate it with the help of adhesive tape or electrical tape - they will certainly be found, if not in your car, then in those passing by. There is also another option.
Provided that the length allows, the pipe is cut off, cutting off the damaged part, and put on again. However, if the leak is in the middle, then this will definitely not help.
It should be noted, in addition to eliminating the problem, you should also add coolant. Many motorists often carry it with them, throwing it in the trunk. If you didn’t have antifreeze, try your luck by stopping other cars. At positive temperatures, ordinary water is quite suitable.
Another problem quite typical for the “six” is that the stove begins to alternately supply either warm or cold air to the cabin. The main reason in this case is an air lock formed in the cooling system of your car. It can appear, for example, due to:
- damage to the expansion tank plug valve;
- violations of the tightness of the connection of pipes;
- air ingress when pouring antifreeze.
The most serious thing that can happen in this case is the failure of the heater fan. The procedure for its repair is quite complicated, so you should not expect to carry it out in the field. It is best to get to the first car service, where you will fix the problem, or to the auto parts store - here you will get the parts you need. However, the first option is still preferable, especially if you are far from home. Repairing the stove fan "on the knee" is incredibly difficult.
And finally, consider another situation. The regulator is moved to the maximum heating position, while not hot, but barely warm air enters the cabin. Most often this happens if the engine of your car has not yet warmed up to operating temperature. However, this is an elementary moment that almost everyone knows about, even novice drivers. Accordingly, the first thing we look at the indications of the arrow. If it is below 90 degrees, then you should wait until the engine is fully warmed up. However, this situation may well arise due to a failed thermostat. The first sign of this is that the engine cannot warm up to 90 degrees, although it has been running for quite some time.
After that, it remains only to close the expansion tank and enjoy a comfortable temperature in the cabin.
What to do if the stove blows warm air
If the heater does not want to maintain an optimal microclimate in the cabin, if it blows warm, not hot air, then the problem should be looked for in the engine temperature. If the power unit does not warm up more than 90 degrees, then most likely the thermostat will need to be replaced. In addition, the reason may lie in the breakdown of any components of the motor, which can only be detected and eliminated in a specialized service.
The stove does not turn on at all: we are looking for the causes of the problem
The most unpleasant situation occurs when, in severe frost, the heater does not want to start at all. In this case, you will need to either contact the service, or, if you have the appropriate experience, independently find and eliminate one of the following breakdowns:
- failure of the fuse in the mounting block. Repair in this situation includes a fairly simple replacement of the burnt part;
- problems with the heater start button. To identify them, you need to connect the wires directly to the battery. If the stove starts, install a new button;
- oven motor failure. The most serious problem that requires complex repairs.
Problems with the stove radiator tap
If the heater of your car constantly blows cold air, despite the fact that the motor is working properly, it is necessary to check the performance of such a part as the radiator tap. It should open immediately after you start the stove to ensure proper circulation of the coolant.
If this does not happen, then the problem may lie in the system mode switch itself. Also, quite often the cable connecting the lever to the radiator tap fails. These parts are non-repairable and should be replaced if found to be defective.
Furnace turns off while driving
Another common problem is the sudden shutdown of the heater literally on the go. If you are driving at speed and the heater suddenly starts blowing cold air, the first thing to do is to check the level in the coolant system. Most often, such a breakdown occurs due to leakage of antifreeze or antifreeze caused by damage to the hose or pipe, as well as depressurization of the connections.
To fix the problem, you can either replace the pipe, or temporarily close the damaged area with electrical tape or tape - this will allow you to more or less comfortably get to the nearest car service, eliminate the leak and replenish the coolant level.
