Accessory Drive Belts



Correct drive belt tension is required to ensure optimum performance of the belt driven engine accessories. Use the correct gauge when checking belt tension; there are different types of adjustment gauges for checking either a serpentine or a V-type belt. Refer to the instructions supplied with the gauge. Place gauge in the middle of the section of belt being tested (between two pulleys) to check tension. Do not allow the gauge (or gauge adapter) to contact anything but the belt.

It is not necessary to adjust belt tension on the 3.7L. 3.9L or 5.9L engines. These engines are equipped with an automatic belt tensioner. The tensioner maintains correct belt tension at all times.

2.5L Engines

Belt tension is adjusted at the power steering pump bracket and idler pulley assembly.

  1. Disconnect negative battery cable from battery.
  3. Loosen idler pulley bolt.
  5. Loosen tension adjusting bolt.
  7. Adjust tension adjusting bolt until reading is within specification.
  9. Tighten idler pulley bolt and re-check belt tension. Adjust if necessary.

Belt Tension 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.

Drive Belt Routings

The belt routing schematics are published from the latest information available at the time of publication. If anything differs between these schematics and the Belt Routing Label, use the schematics on Belt Routing Label. This label is located in the engine compartment, usually on the fan shroud.
