when your motor is at normal operating temp the fan should just idle, ie. when you rev the motor the fan shouldnt howl.
First thing in the morning when you start you should hear the fan for a few minutes then it should settle down and stop working hard. Here in N Z the wreckers are flat out sellinghubs as they are all packing up, they have a limited life.
I recently fitted an american aftermarket hub to an ea and itwas tighter than the ford item. Basically if you hub is tight(not necessarily seized), then it will constantly howl or drone, you wont hear the normal engine noises over it. Eventually it will stuff your fan belt and possibly even the fan will fly apart as they are not meant to work so hard.
