Why Does the Fan Keep Running After the Engine Is Turned Off?
1 Answers
It is normal for the fan to keep running after the engine is turned off. Below is relevant information about the car radiator: Reasons why the fan keeps running after the engine is turned off: If the engine coolant temperature at the moment of parking is higher than the acceptable soak temperature of the engine, the vehicle's computer will automatically calculate the fan's operating speed and duration, thereby controlling the fan's operation. The higher the engine temperature, the longer the fan will run after parking. When the engine coolant temperature drops below the soak temperature, the fan will shut off, thus protecting the engine and extending its service life. Components of the car radiator: The car radiator consists of three main parts: the inlet tank, the outlet tank, and the radiator core. The coolant flows inside the radiator core, while air passes outside the radiator. The hot coolant cools down by dissipating heat to the air, and the cold air warms up by absorbing the heat from the coolant.
