fan

(Otomotiv) A fan clutch iş a thermostatically-controlled device that exists as an integral component of the automotive cooling system. When the engine iş cool or even at normal operating temperature, the fan clutch partially disengages the engine's mechanically-driven radiator cooling fan, generally located at the front of the water pump and driven by a belt and pulley connected to the engine's crankshaft. This saves power since the engine does not have to fully drive the fan
