Thanks?
The fan should always be spinning, even if the clutch is not engaged. The fluid in it creates some drag so that it spins, but slips. When working properly, the fluid increases the drag in the clutch, reducing slippage, so that the fan runs faster and draws more air. Freewheeling at shutdown is a sure sign the clutch is garage and has been junk for a long time. A good clutch will stop just about immediately or maybe coast a fraction of a rotation. Replace it. A fan clutch is cheaper and easier than a head gasket.
