Re: 2000 5.3L z71 whining noise

The sound definately appears to be coming from the area of the serpentine belt. I could not isolate it but it was near the alt.

Any suggestions on what the most common malfunction would be?

Also, is the noise in the belt and tension or is it possible that the alt could actually be making that noise?
