Pacific Automotive Network car radiator fan turns on automatically. Nowadays, the radiator fan usually has two speeds: no rotation at low temperature, one speed for medium temperature, and two speeds for high temperature.
The car water tank fan turns on automatically. Nowadays, the water tank fan generally has two speeds. It does not work at low temperature, one speed for medium temperature and two speeds for high temperature.
When the engine water temperature is high, the water pump circulates the water repeatedly to reduce the engine temperature (the water tank is made of hollow copper tubes .High temperature water enters the engine water tank and is cooled by air circulation to the engine cylinder wall to protect the engine if the water temperature is too high.low in winter, the water circulation will be stopped at this time to prevent the engine temperature from being too low.
If it turns out that there is a lot of antifreeze in the water tank, special antifreeze of the same brand should be filled in time. “Boiling pot” is likely caused by a lack of antifreeze. Be especially careful not to add tap water, because the chlorine in tap water will corrode and rust the water tank, engine and other systems, prevent the cooling system from cooling smoothly and will cause the engine temperature to be too high.
