Chevrolet Repair: engine accessory drive belt, car engine, somthing

Question
At least it sounds like the noise I hear is coming from that big belt. I hear a kindof squeaking/or somthing that needs to be oiled noise. Please help?
Can you give me an idea of what you think this might be?
Thank You,
Becky Rocha

Answer
Probably just a bad belt, change the belt and the noise should go away, however once the belt is removed, spin each pulley to see if the noise is present with the belt off, you left out a lot of information ( year, make and model of car, engine size ??? )  so this is the best general answer I can give you
