Experts of Avtovzglyad led list the most common reasons why a car stove stops working. To find a problem, sometimes you have to shake the system “from and to.”
First of all, experts advise, it is necessary to check the operability of the fan – the “motor”, which accelerates the warm masses of air through the interior of the car. His work should be accompanied by a quiet rustle without “wheezing, sobbing and cod.” If in all modes, the fan runs smoothly, then the cause of the malfunction is most likely under the hood.
It is necessary to check the level of antifreeze in the tank, since the interior heating system is inextricably linked with the cooling system. Another possible reason is the air plug in the pipes of the cooling system, which will have to be driven out.
Next is the thermostat. Due to accumulated dirt and rust, its damper loses its mobility, therefore, antifreeze can go in a “small circle”, bypassing the radiator. As a result, the stove is not involved in the process, and heat does not enter the cabin. There is only one way out – replacing the thermostat and antifreeze.
