How to Change the Tensioner Pully on a 94 Dodge Caravan
The tensioner pulley on a 1994 Dodge Caravan serpentine belt tensioner assembly allows the transference of tension from the tensioner to the belt. The pulley itself has an internal bearing ring so it can rotate freely at the end of the serpentine belt tensioner arm. If the bearing ring gives out, the pulley will either wobble or seize, neither of which is conducive to continued serpentine drive system operation. Unfortunately, the pulley itself is not serviceable. However, Dodge does offer the entire tensioner assembly. Anyone with good mechanical aptitude can change a Caravan tensioner in about an hour.
Instructions
- 1
Lift the Caravans hood and support it with the prop rod. Examine the belt routing diagram sticker, placed on the fan shroud or underside of the hood, to verify the location of the belt tensioner on your specific Caravan.
2Rotate the Caravans serpentine belt tensioner assembly clockwise to relieve the tension on the belt. Slip the belt off the tensioner with your free hand before rotating the tensioner back to its home position. Remove the tool.
3Extract the two mounting bolts that hold the serpentine belt tensioner assembly to the Caravans front engine cover using your socket set. Depending on your physical size and dexterity, you may find this easier to accomplish through the top of the engine well or through the passenger-side wheel well.
4Pull the old serpentine belt tensioner assembly out of the Caravans engine bay by hand. Place the new serpentine belt tensioner assembly on the Caravans front engine cover and bolt it in using your socket set.
5Rotate the new serpentine belt tensioner assembly clockwise with the serpentine belt tool and then place the belt on the pulley by hand. Rotate the new serpentine belt tensioner assembly back into place. Remove the tool and close the hood.
