A single serpentine drive belt is located at the front of the engine and plays an important role in the overall operation of the engine and accessories. Due to its function and material makeup, the belt is prone to failure after a period of time and should be inspected periodically. With the engine off, locate the drive belt at the front of the engine. Using your fingers (and a flashlight, if necessary), move along the belt, checking for cracks and separation of the belt plies. If the belt looks worn, replace it. Also check for fraying and glazing, which gives the belt a shiny appearance. Both sides of the belt should be inspected, which means you will have to twist the belt to check the underside. Check the pulleys for nicks, cracks, distortion and corrosion. Check the ribs on the underside of the belt. They should be all the same depth, with none of the surface uneven. The tension of the belt is automatically controlled by a tensioner, so the tension does not need to be adjusted. To replace the belt, use a breaker bar and socket to rotate the tensioner counterclockwise. This will release the tension so the belt can be removed. When the belt is out of the way, release the tensioner slowly so you don't damage it. Take the old belt with you when purchasing a new one to make a direct comparison for length, width and design. When installing the new belt, make sure it is routed correctly. Also, the belt must completely engage the grooves in the pulleys.

The pulleys should be checked for nicks, cracks, distortion, and corrosion.
