Details regarding the Serpentine belt Adjustment

It is not necessary to adjust belt tension on the 3.7L, 4.7L or 5.7L engines. These engines are equipped with an automatic belt tensioner. The tensioner maintains correct belt tension at all times; consequently, do not attempt to use a belt tension gauge on these engines.

Details Regarding Belt Inspection

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.

Removal & Installation Procedure for Drive Belt:---

  1. Disconnect negative battery cable.
  2. Rotate belt tensioner until it contacts its stop. Remove belt, then slowly rotate the tensioner into the freearm position.

  1. Install new belt. Route the belt around all pulleys except the idler pulley.
  2. Rotate the tensioner arm until it contacts its stop position.
  3. Route the belt around the idler and slowly let the tensioner rotate into the belt. Make sure the belt is seated onto all pulleys.
  4. With the drive belt installed, inspect the belt wear indicator. On 4.7L Engines only, the gap between the tang and the housing stop (measurement A) must not exceed 24 mm (.94 inches). If the measurement exceeds this specification replace the serpentine accessory drive belt.
