Grand Cherokee 2WD V8-5.2L VIN Y (1998)
NOTE: On 5.2/5.9L engines, the tensioner is equipped with an indexing arrow (Fig. 65) on back of tensioner and an indexing mark on tensioner
housing. If a new belt is being installed, arrow must be within approximately 3 mm (1/8 in.) of indexing mark (point B-) (Fig. 65). Belt is considered
new if it has been used 15 minutes or less.
If the above specification cannot be met, check for:
The wrong belt being installed (incorrect length/width)
-
Worn bearings on an engine accessory (A/C compressor, power steering pump, water pump, idler pulley or generator)
-
A pulley on an engine accessory being loose
-
Misalignment of an engine accessory
-
Belt incorrectly routed.
NOTE: A used belt should be replaced if tensioner indexing arrow has moved to point-A (Fig. 65). Tensioner travel stops at point-A.
