Saab 9-3 Problem Report
Saab 9-3 Noise from Serpentine Belt Idler Pulley
The idler pulley for the serpentine belt can fail causing noise from the belt area. Our technicians report the pulley has been known to fail completely which can cause the belt to break or be thrown off.
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. - Visitor
pulley failed causing belt to rip - Visitor
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 - Visitor
Not fixed yet, but told idler pulley bearings are worn, causing it to rattle. - westender
