The fan clutch is a coupling between the water pump and the fan blade that allows the fan to be operational at low speeds and disconnected at higher speeds. With the engine off, and the engine cold, the fan should be free to turn. Once the engine is warmed up, the fan should be much more difficult to turn. It also should not free turn after the engine is shut off.
