Judy, sorry I didn't see Troy's post. It was I that told him it was probably the idler pulley and on the drive back home, I kept thinking about it and wondering if it may in fact be the water pump. Just had that nagging feeling for some reason. They are not difficult to replace, but you have to take your time, and as already said, make sure you get the right bolts in the right holes. Tell Troy I'm sorry for giving him the bumb dope on the pulley.
