serpertain belt

[PlayStation3]

hi, i am going to be getting my serpertain belt replaced b/c it is squaking like a m/f when it starts some time and when i come to a stop. i will be getting a gatorback belt and a new tensioner on. now is there anything else that could cause the squeaking the belt on it is only 3 months old. it is a carquest belt

make sure you check your idler pulley too, along with the tensioner.
