Hello again, 78 NYB is still squealing above 1500 rpm or so. Belts are tight and I don't think it's coming from there. One suggestion I got was that it could be the fan clutch. When I put my stethescope on the water pump housing(close as I can get to the fan clutch), the squeal sounds like its coming from there. May I assume that it's coming from either the water pump or the fan clutch, and if so, is there a way to isolate the problem between the two, or do I just have to replace both? thanks Bruce s __________________________________ Do you Yahoo!?
