SERPENTINE DRIVE BELT
The serpentine drive belt used on 1981-83 Jeep models can be expected to develop some random cracks in one or more of the belt ribs during the
life of the belt.
These random or sporadic cracks are a normal development that usually occurs during the latter part of the belt's service life. The cracks do not
affect belt performance and actually improve belt flexibility.
The only time belt replacement for rib cracking is warranted, is when the cracks are at or beyond the full depth of the rib, or if some of the cracks
run parallel to the belt ribs.
Make a note of this information in the serpentine drive belt diagnosis charts in Chapter 1C of the 1981-82 Jeep Technical Service Manuals.
