Fan Clutch - E31, E32, E34, E38, E39 with M60/M62 V8

This is the viscous fan clutch for the for the engine fan on M60/M62 V8 engines. When the engine is cool or even at normal operating temperature, the fan clutch partially disengages the engine's mechanically-driven radiator cooling fan. This saves power, since the engine does not have to fully drive the fan. If engine temperature rises above the clutch's engagement temperature setting, the fan becomes fully engaged, thus drawing a higher volume of ambient air through the vehicle's radiator, which in turn serves to maintain or lower the engine coolant temperature to an acceptable level.Typically, when the fan clutch fails the car with tend to overheat at idle or in slow moving traffic.
