hello everyone i am new and this is my first post. i have just purchased a 2001 gtp and i have some loud whining noise coming from the passenger side of the motor. it goes away when at low rpm, and at higher rpm like 3000 it is really nasty sounding. like a rough whining, could this be the pulley on the s/c pulley or the bearing on the pulley going out. any advice would get helpful
