Accessory Drive Belts

Adjustment



All engines use an automatic drive belt tensioner. No adjustment is necessary. If the tensioner is at Maximum travel, the belt is most likely stretched or the incorrect belt was installed.

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.

3.1L Engine

NOTE
Routine inspection of the belt may reveal cracks in the belt ribs. These cracks will not impair the belt performance. The belt should be replaced if the belt slip occurs if a section of the belt ribs are missing. A single serpentine drive belt is used to drive all engine accessories. All belt driven accessories are rigidly mounted with the belt tension maintained by a spring loaded tensioner. The indicator on the movable portion of the tensioner must be within the limits of the marks of the stationary portion of the tensioner. Any reading outside of these limits indicates either a defective belt or tensioner.

  1. Remove engine mount.
  2.  
  3. Rotate the drive belt tensioner in a clockwise motion using a box end wrench.
