A worn idler pulley can show up as a chirp, squeal or rumble near the belt, or as a pulley that feels rough or wobbles when turned by hand with the engine off and cool. A tired belt can make the same noise, so these signs alone do not prove the pulley is the problem. Each engine takes one pulley in the upper alternator position.
