new serpentine belt
I put a belt on from autozone and it squeals when I start it or rev it up. Do I tighten it? Loosen it? I've tried both and it doesn't change a thing?

Tighten it. The belt on the 4.0 needs to be awfully darn snug to stay quiet. I have had to retighten every belt I've installed on my 99 after driving it for a bit (they stretch a little).
