Before my idler pulley failed, I would hear a high pitched whine upon start up for 5 minutes or so and then at high rpm. Pulley finally failed, broke in half and caused the car to run hot.

Started hearing high pitched whine on startup, literally days later on a cold, cold start (-25 C) the outer ring separated from the spokes and shredded the belt while the car was warming up. Came back to a dead battery but that was the only damage other than the belt and pulley
