Why does the Volkswagen car's fan keep running after turning off the engine?
1 Answers
Volkswagen car's fan keeps running after turning off the engine for cooling purposes. Here are the reasons why the Volkswagen car's fan keeps running after turning off the engine: Cooling: If the engine coolant temperature at the moment of parking is higher than the acceptable soaking temperature of the engine, the onboard computer will automatically calculate the fan's operating speed and duration, thereby automatically controlling the fan's operation. The higher the engine temperature, the longer the fan runs after parking; when the engine coolant temperature is lower than the soaking temperature, the fan turns off; this protects the engine and extends its service life. The radiator should not come into contact with any acid, alkali, or other corrosive substances.
