With the advent of winter, many owners of "nine" are faced with the problem of heating in the cabin. Sometimes the stove gives out an air temperature of 5-10 (rarely 15) degrees Celsius, and this is with a 90-degree coolant! In this situation, the windows often fog up, including the windshield, which significantly affects visibility. And this trend is observed in almost all domestic cars. Therefore, often the owners of such machines finish this device, as they say, bring to mind.
So, let's figure out what to do if your stove does not heat well or does not work at all. VAZ-2109 is a model in which this problem is completely solvable.
Causes of failure and their elimination
Most often, this part malfunctions due to the lack of coolant in the engine system, which is strictly unacceptable even in the summer. But everything happens on the road, and even if you poured this liquid into the tank, you should not relax, since the VAZ-2109 stove can break at any second due to an unpressurized tank. Therefore, from time to time, pay attention to the presence of antifreeze in your car.
Also, clogging of the system may cause a breakdown or supply of cold air instead of hot air. The VAZ-2109 stove should not have any pollution. And in order to prevent this, it should be checked annually before the start of winter for the presence of foreign bodies in the form of fluff, dust and leaves.
A heating radiator can also affect the coordinated operation of this mechanism. In order to make sure that it is serviceable or unsuitable, you need to measure its temperature during operation. To do this, just touch the surface with your hand. If the radiator is hot, it means that the VAZ-2109 stove will work well, but if it is cold, the breakdown must be immediately eliminated. Most often, an air plug breaks in the radiator. In order to enjoy the warm air in the winter again, you need to raise the vehicle to any height (this can be a flyover or a curb). After the front axle has become higher than the rear, you need to put the car on the handbrake and let the engine run at medium speeds for at least 1-2 minutes. But if this does not help, then the breakdown is the leakage of the system. Here improvised methods will not help - you need to without hesitation contact the service station and check the radiator for chips and holes. And the best thing, of course, is to replace such a spare part, and then the VAZ-2109 stove will work for a long time.
The heating system also heats poorly because of the cabin filter. It significantly affects the operation of the heating system. And despite the fact that this element only cleans the interior of dust, due to its malfunction, the VAZ-2109 stove will not work or will barely supply cold air. There is no need to do any repairs here - it is better to immediately replace the filter with a new one, especially since the price for it is quite acceptable. Also, along with its installation, it is recommended to protect the air intake. This allows you to increase the life of the filter and reduce the frequency of breakdown of the stove.
So, we figured out the main reasons for the breakdown of this unit and found out how to fix them. Following these rules, you will never be wondering: "Why does the VAZ -2109 stove get badly heated?"
