He replaced the tensioner this morning I believe. It sure did sound like it was coming from the water pump, and it was a high pitched bearing squeal!! It sounded as if it was either water pump or alt, but the noise was really up higher sounding. Also I think the alt is fairly new, although that doesn't of course rule it out.
Hopefully he can remove the serp. belt and will be able to "feel" which component is failing. It ain't a pretty noise.......
