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.This item is in the category "Vehicle Parts & Accessories\Car Parts & Accessories\Engine Cooling Components\Other Engine Cooling Components".
