When the coolant temperature is too high after parking, the onboard computer will automatically calculate the fan speed and duration. The higher the temperature, the longer the fan runs, thereby protecting the engine. Solution: You can try disconnecting the fan wiring harness to perform a separate power cut. Function of the fan: The car fan has a cooling function. When the coolant temperature is too high after parking, the onboard computer will automatically calculate the fan speed and duration.
