Just to add to what's already been correctly said about clutch fans. One good way of knowing if a thermal clutch fan is in correct operating order is to listen to it on initial start up. It should be engaged after the start up causing the fan to roar until it realizes it's not hot and then allows the fan to quietly freewheel. I've found that when a fan passes this initial test you can be confidently assured that it will engage when the radiator temperature creeps up. It shows that the internal viscous mechanisms are complete and in correct operating order. Rob
