I'm wondering what all the pulleys are for that the Serpentine Belt goes around. Also, my belt was making noise like chirping noise so I changed the tensioner pulley and belt, and I can still hear noise. It's not nearly as bad though. Sounds like it's coming from the alternator area or engine. I don't know.

Yep, I would have the belt off and then spin the pulleys to see which one is making noise. I have seen the AC clutch pulley make this noise as well, look for rust colored dust around the pulley which is a sign that the bearing is bad. Check out the images (below). Please let us know what happens.
