CAUTION
Do not check belt tension with engine running.

Air Conditioning Compressor & Power Steering Pump

The automatic belt tensioner maintains proper tension on the power steering/air conditioning belt. After belt is installed, inspect belt length indicator marks. The indicator mark should be within the minimum belt length and maximum belt length marks. On a new belt, the indicator mark should align approximately with the nominal belt length mark.

Alternator Belt

Check belt tension using Special Tool 8371 - Belt Tension Gauge Adapter, and the DRBIII® using the following procedures:

  1. Connect 8371 to the DRBIII® following the instructions provided with tool.
  2.  
  3. Place end of microphone probe approximately 1 inch (2.54cm) from belt at one of the belt center span locations
  4.  
  5. Pluck the belt a minimum of 3 times. (Use your finger or other suitable tool).
    1. The frequency of the belt in hertz (Hz) will display on DRBIII® screen
    2.  

  6.  
  7. Adjust belt to obtain proper frequency (tension) by tightening the adjusting bolt and set belt tension to the following specifications:
    1. New: 135 lbs. (224 -252 Hz)
    2.  
    3. Used: 70 lbs. (172 -181 Hz)

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.
