Anne Marie Blaire Columbus, Ohio - 2002 Saab 9-3
Anne Marie’s car is making a humming type noise--it starts when she starts the car, and gets louder as she accelerates. The noise is coming from under the hood. It happens when the car is standing still, but only gets louder when accelerating. Problem is likely the belt tensioner--bearing is worn out. She should get it fixed, or stuff riven by the belt will start to fail.
