What happens when the radiator fan burns out?
If the cooling fan motor burns out, the cooling fans will then, in turn, be disabled. Since the cooling fan motors work in tandem with the fan blades to pull air through the radiator, the blades will then not be able to spin or cause any airflow to cool off the car.
