Re: screach when running
did you try pouring water on the belt with the engine running to see if the screeching stops? I had a screeching noise that we thought was a pulley, the belt looked fine, but it ended up being the belt...

Re: screach when running
Most likely the belt idler tensioner. Very common in these engines throughout the GM lineup.
