What's wrong with the popular warm air?

The reasons are: the engine lacks coolant, such as adding coolant; The thermostat is damaged or normally open. If the thermostat is damaged, it should be replaced; If the engine cooling system has air resistance or blockage, just remove the fault; The heater tank is dirty and blocked. If it is, it must be cleaned or replaced.

An introduction to the investigation methods of the reasons why the automobile warm air is not hot;

1. Check whether the engine is short of coolant. If there is a shortage of coolant, just make it up.

2. Check whether the thermostat is damaged or always open. Thermostats often meet to keep the cooling system in a big cycle. When the car is running, the outside temperature is very low, and the cold air will quickly cool the antifreeze, so the engine water temperature will not come up and the warm air will not be hot.

3. The water pump impeller is damaged or lost, so that the flow through the warm air small water tank is not enough, and the heat cannot come up.

4. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and not hot warm air.

5, the car's warm air small water tank can not dissipate heat, which will lead to the temperature of the warm air not coming up. At this point, first check whether the filter element is dirty or blocked, clean it, and replace it in time if necessary.
