    Dayco 89614 belt tensioner for the 2011-2013 BMW 335is 6-cylinder 3.0L and other vehicles keeps the accessory drive belt at the right tension. It presses against the belt to hold that tension as the belt wears.

    Quick facts

    • Part: Dayco 89614 belt tensioner

    A worn Dayco belt tensioner can show up as belt squeal, a chirp from the belt area or uneven wear on the belt edge. These signs alone do not prove the tensioner is at fault, since a stretched or glazed belt can squeal too.
