The Isuzu fan blade provides valuable assistance to the cooling system in your vehicle, supplementing the flow of air that comes into the engine compartment through the grille when necessary to prevent your engine from overheating. The cooling system must have a constant flow of cool air through the radiator to assist in the dissipation of engine heat, generated at normal driving speeds by the motion of the vehicle. At times, when the vehicle is idling or moving slowly, inching along in that rush hour traffic jam, the flow of air into the engine compartment is not sufficient to control the engine temperature. At these times, the Isuzu fan blade takes up the slack, rotating to pull cool air in through the grille and radiator. In newer model vehicles, the Isuzu fan blade is most often powered by an electric motor, equipped with a thermostatic switch that will cause it to rotate when the air temperature in the engine compartment reaches a level that indicates its need to control the engine temperature. In many older model vehicles, the Isuzu fan blade is powered by a belt and pulley system, taking its power directly from the engine to rotate. Often these belt driven models of the cooling fan include a fan clutch for efficiency, which uses a thermostatic device to initiate the rotation of the Isuzu fan blade only when it becomes necessary to aid in engine cooling.
