need help diagnosing a startup squeal on a 2001 pontiac grand am se?

[MarlonB]

I couldn't tell whether the squeal was coming from the belt or the altenator so i had the belt replaced.... That stopped the constant squeal and the squeal that existed when turning tight corners, but there is still a startup squeal.. Any suggestions??????

Check your to see if your belt tensioner is worn - take the belt off and check how easily it spins,and side to side motion on the pulley
