 The GMC cooling fan is a component in the cooling system of your vehicle, assisting in the supply of cool air necessary for the engine cooling process. The engine cooling system requires a flow of cool air to dissipate the heat of the engine, keeping its temperature to a safe level to prevent overheating. The cooling system uses a liquid coolant to remove heat from the engine, circulating it through to reduce engine temperature. As the coolant travels out of the engine, it carries the heat collected from the metal surfaces through the system to the radiator. Once it reaches the radiator, the liquid coolant travels through the winding path of the radiator cooling cores, the heat it carries dissipated by the cool air that flows through the radiator.
 This air is supplied primarily by the motion of the vehicle, and flows in through the grille and radiator. When the vehicle is moving slowly or idling, the GMC cooling fan provides the airflow necessary for the cooling process. The GMC cooling fan is powered by an electric motor in many vehicles, while in others a belt and pulley system uses direct engine power to operate the GMC cooling fan. The belt driven GMC cooling fan is most common in older vehicle models, while most late model vehicles use the electric powered version, especially those that use a front wheel drive system.
