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 its components. Due to its function and material makeup, the belt is prone to wear and should be periodically inspected. The serpentine belt drives the alternator, power steering pump, water pump, and air conditioning compressor. With the engine off, open the hood and use your fingers (and a flashlight, if necessary) to move along the belt, checking for cracks and separation of the belt plies. 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 ribs on the underside of the belt. They should all be the same depth, with none of the surface uneven. The tension of the belt is maintained by the tensioner assembly and isn't adjustable. The belt should be replaced at the mileage specified in the maintenance schedule or if it is damaged or worn. To replace the belt, rotate the tensioner counterclockwise to release belt tension. Remove the belt from the auxiliary components and slowly release the tensioner. Route the new belt over the various pulleys, again rotating the tensioner to allow the belt to be installed, then release the belt tensioner. These models have a drive belt routing decal on the radiator shroud to help during drive belt installation. The serpentine drive belt routing diagram is located on the radiator shroud.
