The Buick fan blade is essential to maintaining a safe operating temperature for the engine of your vehicle. The engine cooling system needs a constant supply of cool air to perform its function. Your engine is cooled by a flow of liquid coolant that is directed through the engine to collect heat from its metal surfaces in order to reduce engine temperature. This liquid emerges from the engine carrying the heat it has gathered and proceeds through the cooling system to the radiator, where the heat is dissipated with a flow of cool air as it passes through the winding path of cooling cores. The motion of the vehicle produces this airflow when the vehicle is moving at normal driving speeds, but the assistance of the Buick fan blade is needed for good airflow when the vehicle is moving slowly or at an idle. In some systems the Buick fan blade is powered by an electric motor that uses a heat sensing device to measure the temperature of the air in the engine compartment, switching on to rotate the Buick fan blade only when its help is necessary, conserving power. Other systems, generally those in older model vehicles, are belt driven. Many of these belt driven systems use the fan clutch to provide a variable speed for the motion of the Buick fan blade, causing it to rotate only when the extra airflow it provides is necessary to cool the engine.
