Drive Belt: Testing and Inspection

Serpentine Belt:







Inspect
^ Routine inspection of the belt may reveal cracks in the belt ribs. These cracks will not impair belt performance and therefore should not be considered a problem requiring belt replacement.
^ The belt should be replaced if sections of the belt ribs are missing or if the belt is outside of the tensioner's operating range. See illustration.

Important
^ Belt tension is maintained by the tensioner and is not adjustable.
