There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, high water temperature and not hot warm air. If there is air in the cooling system all the time, it is likely that the cylinder pad is damaged and air leaks into the cooling system. If the inlet pipe of the small warm air tank is very hot and the outlet pipe is very cold, this situation should be that the small warm air tank is blocked and should be replaced.

Precautions:
It is necessary to open warm air in cold winter. However, using warm air in summer is different from using air conditioning. Improper use will lead to increased power consumption, no temperature rise, dry mouth and so on.
Don't turn on the warm air immediately when the cold car starts in winter. This not only does not have warm air, but also increases the burden on the engine. Because the car just started and the water temperature didn't come up. The engine should be warmed up first, and then the external circulation mode should be started.
When the warm air is turned on, the temperature should not be too high. If it is too high, it will be dry, and the skin will lose water and age faster. If the distance is far away and the warm air temperature is too high, it will make people sleepy and increase the risk factor.
