It stops for a few seconds. History: For several months an occasional squealing has gotten real bad. I've taken the one year old belt off several times and turned every pulley and they make no noise and have no play. Last month though the year old water pump did have a little play and made some noise and had some dribble marks by the weep hole so I changed it. When I had it in my hand it had some play and made some noise. I thought that was it for sure, but noooo. The squealing is back. Like I said when I pored water on it the squealing stops, that seems to be key, but to what? ANY ideas?
