The fan clutch is a device controlling the engagement of the EC fan. A valve inside the clutch regulates the flow of a special silicon oil. The oil transmits the engine’s torque thus, rotating the fan. The fan clutch can be driven by a belt and pulley or directly by the engine when mounted on the engine’s crankshaft. Depending on the cooling needs, the fan can be engaged partially or fully - saving the engine power used for the power transmission. There are two design types of the sensor causing the clutch to engage. One with a bi-metallic, thermostatic sensor controlling the engagement and another controlled electronically by ECU signals, influenced by engine/transmission oil temperature, coolant temperature, AC system pressures or ambient air temperature.
