A serpentine 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 make up, 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 underside of the belt. They should be all the same depth, with none of the surfaces uneven. The tension of the belt is maintained by a spring-loaded tensioner assembly and isn't adjustable. The belt should be replaced when the mark on the moveable part of the tensioner moves out of the acceptable range on the stationary part of the tensioner. To replace the belt, rotate the tensioner to release belt tension. Remove the belt from the tensioner and 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. To replace a tensioner that has lost its spring tension, exhibits binding or has a worn-out pulley/bearing, remove the mounting bolts. Installation is the reverse of the removal procedure.
