Dayco 89632 belt tensioner for the 2013-2018 Ram 1500 V6 3.6L and other vehicles holds the serpentine belt at working tension on the engine's belt drive. This Dayco belt tensioner is an automatic type that takes up slack in the belt.
A squealing or chirping belt, a belt that flutters, or a pulley that wobbles can mean the tensioner is wearing out. Noise can also come from the belt or another pulley, so with the engine off and cool, look the belt over for cracks and glazing and check the tensioner pulley for wobble or rough wear before you replace anything. If the tensioner is the cause, this one replaces it.
This belt tensioner fits the 2013-2018 Ram 1500 V6 3.6L, the 2011-2025 Jeep Grand Cherokee V6 3.6L and the 2011-2023 Dodge Charger V6 3.6L, and each takes one. If your vehicle is not named here, look up your year and engine in the "Vehicles it fits" section.
