INSPECTION



See Figures 1 and 2

Inspect the belts 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.

Routine inspection of the belt may reveal cracks in the belt ribs. These cracks will not impair belt performance and therefore should not be considered a problem requiring belt replacement. However, the belt should be replaced if belt slip occurs or if sections of the belt ribe are missing, sometimes referred to as chunking.

Inspect the marks on the tensioner for the wear limits. If a whining is heard around the tensioner or idler assemblies, check for possible bearing failure.

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.

REMOVAL & INSTALLATION

  1. Disconnect the negative battery cable.
  2.  

The proper belt routing is included in this section, however, it is a good idea to make a simple drawing of the belt routing of your engine for installation reference before removing the belt.

  1. Rotate the drive belt tensioner to relieve the belt tension. The procedure is as follows:
    1. On the 2.2L engine, use a 15 mm drive tool or a special belt removal tool to rotate the tensioner clockwise.
    2.  
    3. On the 2.3L and 2.4L engines, use a 13mm drive tool or a special belt removal tool to rotate the tensioner clockwise.
    4.  
    5. While holding the tensioner back, remove the belt from around one pulley.
    6.  

  2.  
  3. Remove the belt from around the remaining pulleys.
  4.  

To install:
  1. Position the belt around the pulleye in the proper routing with the exception of one pulley. It is easiest to keep the belt off of the easiest pulley to access. Hold the belt tight with your hands and using the proper tool for your engine, rotate the tensioner clockwise and place the belt around the final pulley.
  2.  
  3. Release the tensioner slowly until it site firmly against the belt.
  4.  

If the tensioner doee not touch the belt or the wear indicator marks are not within specification, the belt is routed incorrectly or the wrong belt has been installed.

  1. Connect the negative battery cable.
  2.  
  3. Start the engine and ensure that the belt runs smoothly and no abnormal noises exist.
  4.
