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.
Same problem hearing a high pitch whining when i first start, then it goes away after10 seconds i believe its time to change the serpentine pulley, honestly i bought this car with 60k on it and its been in the shop twice a year for something.What i steming pile but my wife had to have it. cant sell it,its like a mother in law.
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
