The belts used on these vehicle are equipped with automatic (spring load) tensioners which maintain tension. No adjustment is necessary or possible.
Drive Belt Routings
Visually inspect the belt for obvious signs of mechanical damage:
Eliminate all other non-belt related noises that could cause belt misdiagnosis, such as A/C compressor engagement chirp, power steering cavitations at low temperatures, variable camshaft timing (VCT) tick or generator whine.
If a concern is found, correct the condition before proceeding to the next section.V- Ribbed Serpentine Belt With Piling
The condition of the V-ribbed drive belt should be compared against the illustration and appropriate action taken.
- Small scattered deposits of rubber material. This is not a concern, therefore, installation of a new belt is not required.
- Longer deposit areas building up to 50 percent of the rib height. This is not considered a concern but it can result in excessive noise. If noise is apparent, install a new belt.
Heavy deposits building up along the grooves resulting in a possible noise and belt stability concern. If heavy deposits are apparent, install a new belt.
There should be no chunks missing from the belt ribs. If the belt shows any evidence of this, install a new accessory drive belt.
Inspect the drive belt 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.V-Ribbed Serpentine Drive Belt With Cracks Across Ribs
Check the belt for cracks. Up to 15 cracks in a rib over a distance of 4 inches (100mm) can be considered acceptable. If cracks exceed this standard, install a new belt.
Removal & Installation
- Remove the air cleaner outlet pipe.
Rotate the drive belt tensioner clockwise and remove the drive belt.
