The Function of a Cooling Fan: The radiator fan helps to regulate the engine temperature by pulling (or pushing) air through the radiator core. During normal operation, the forward motion of a vehicle forces air into the front grill and through the radiator. This airflow can account for as much as 95 percent of the actual cooling that a radiator performs. When a vehicle isn’t moving, and under heavy load stresses, a cooling fan provides the extra airflow that can prevent an engine from overheating.
