All engines use an automatic drive belt tensioner. No adjustment is necessary. If the tensioner is at Maximum travel, the belt is most likely stretched or the incorrect belt was installed.
Drive Belt Routings
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.
Removal & Installation
- Remove the front fender liner.
- Use the special tool J44811 in order to rotate the drive belt tensioner counter-clockwise to release the spring tension.
