1. Locate the belt tensioner. It is located on the front of the engine, near the top.
2. Insert a 15/16-inch wrench into the tensioner pulley.
3. Turn the wrench counterclockwise to loosen the tensioner pulley.
4. Once the tensioner pulley is loose, you can remove the serpentine belt.
Here are some additional tips for loosening the belt tensioner:
* If the belt tensioner is difficult to reach, you may need to use a long extension on your wrench.
* If the belt tensioner is still difficult to loosen, you may need to use a breaker bar.
Once you have loosened the belt tensioner, you can remove the serpentine belt. Be sure to replace the serpentine belt with a new one before starting the engine.
