Cummins 5333499 Genuine Belt Tensioner Assembly

Replace the old belt tensioner on your Dodge Ram 5.9 diesel with a Cummins 5333499 Genuine Belt Tensioner Assembly. The belt tensioner is designed to keep the correct amount of tension on the serpentine belt. Over time the spring inside the tensioner can start to weaken and the bearing in the pulley can also wear to the point of failure. Symptoms of a tensioner that needs replacement include noise from the tensioner pulley, noise from a slipping belt (lack of tension), or even a belt that comes off the pulley.
