Why is the front end of my 1993 s10 blazer squealing when I first start it up? When it warms up afte a while, it stops. Is it the s-belt? I replaced the water pump and there is no leaking coming from the weap hole, so the bearings should be fine. I notice a little play in the fan, but it's not really that much. The manual says that there usually is a no more than a 1/4 in. play in the fan, and my fan isn't moving that much. No bends in the blades either. Could it be the belt?

The thing is...when i replaced the water pump, i checked all pulleys and no squealing noises were apparent. I put the new pump in; put everything back in place; fired her up and she started squealing. Like i said..it does go away after driving a while. The amperage is good to go on the battery. Could it possibly be the fan causing the belt to squeal? I mean...when do you know its time to change the fan?
