Drive Belt Tensioner: Service and Repair
NOTE: On 5.2/5.9L engines, the tensioner is equipped with an indexing arrow 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 inch) of indexing mark (point B-). 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 (TIC 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. Tensioner travel stops at point-A.
