The GMC Savana Fan Clutch controls cooling fan speed to ensure the engine heats up quickly but does not overheat. Mounted on the water pump pulley and spun by a belt from the crankshaft, the Fan Clutch remains disengaged the majority of the time at low heat levels, reducing drag and saving fuel. Then, as coolant begins to heat up, a viscous coupling will tighten to spin the blades and pull fresh air through the radiator. Early Savana models employed a purely thermal Fan Clutch that depends on a bi-metal spring to detect the temperature and provide an almost on or off signal. Later GMC versions applied an electronically controlled Fan Clutch that reads inputs from coolant, engine oil, transmission fluid, AC pressure, and ambient air to allow graded engagement for finer control. This newer style has a faster reaction time, less fan roar, and less energy loss than the older mechanical design. Regardless of type, the Fan Clutch ensures that GMC engines do not overheat, power is not wasted in acceleration or towing, and the Savana fleet stays reliable on long hauls.
