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.

Wondering how I know the reason for my belt squealing it's progressively gotten worse I changed the belt and the tensioner pulley and it's still doing it. I'm not sure what to do and hoping it doesn't involve taking the belt off because it was horrible trying to get it back on last time I don't know if there's a trick to that or what
