Jeep Drive Belt Routing
Cherokee, Comanche, Wagoneer, Wrangler, Grand Wagoneer
DESCRIPTION
Two drive belt systems are used on Jeep vehicles. The
conventional V-Belt and the single Serpentine or V-Ribbed belt.
The single (Serpentine or V-Ribbed) drive belt system
has been adopted by several manufacturers as a replacement for
multiple V-Belt systems previously offered. The Serpentine belt
requires a suitable belt tensioner similar to those used to control
timing belt tension.
Use of a tensioner allows engine accessories to be mounted
rigidly on the engine. The single belt drive system has a predicted
life of 100,000 miles before replacement is required.
The belt tensioner has a wide functional range and is
capable of maintaining tension during the expected life of the belt.
Tensioner cannot compensate for extreme belt lengths. Poor tension
control and possible tensioner damage can result from excessive belt
length.
INSPECTION
Inspect belt for fraying. If fraying has occurred, ensure
belt and tensioner are aligned properly. See Fig. 1. If tensioner has
reached its limit of travel, belt is excessively stretched and
replacement of belt is required. If excessive noise is noticed from
tensioner or idler, check for possible bearing failure. Small cracks
in the back of the belt are acceptable. Do not apply "Belt Dressing"
or any other additive to serpentine belt.
