whenever i turn my car on my belts squeek and i replaced my power steering belt not too long ago especially when its humid out is when the belt is the loudest... i dont know what belt it is and how do i fix it? because im selling the car and i dont want it to sound like that

 

Sometimes the pully wheels themself wear out and squeak, its not just the belt

 

yea but how would i know which one it is???? cuz i wanna sell the car but when i turn it on sometimes people here that spueek and it makes the car sound like it has problems even though it doesnt
