CORRECT OPERATION


Most modern belt-driven fans have a fluid clutch between the fan and water pump. The fan should spin freely by hand with the engine off and cool, but offer resistance with the engine off and hot.

An electric fan may operate with engine on or off, depending on coolant temperature. If the fan does not operate at all, check for a burned out fuse, or loose electrical connections at the electric motor or coolant temperature sensor.
