The front belt is one accessory belt responsible for turning the water pump, the alternator, the power steering pump and the air conditioning compressor. For the proper engine operation, its condition and tension are crucial; high tension results in bearing abrasion, low tension in slippage and belt noise vibration, and possible failure. Drive belts are made up of multiple layers of material woven together and therefore always under high tension but this tension as well as the heat takes its toll on the belts and they have to be regularly inspect. Belt also incorporates a serpentine tensioner that does not need being adjusting throughout the use of the belt. These vehicles employ a single v-ribbed serpentine belt and this belt goes round in a complicated way round different pulleys. To examine the belt, switch off the engine and take off the hood: flash light should be used in this case to look for signs of possible rubber plies separation, severed cores, rib separation, fraying and glazing of the belt. Admissible imperfections are slight diagonal crack runs and small portions missing from the ribs and, if more than ½ inch chunks are missing from two neighboring ribs, or if noise is produced, substitution is required. Though quite simple in design, the belt sides must be checked, and in order to inspect the bottom side of it, one will have to twist it. To remove the serpentine belt, turn the tensioner anti-clockwise in order to loosen the tension so as to remove the belt from the pulleys. To replace a belt, more often than not, the tensioner has to be in the released position; further, a new belt should be correctly placed and ensure that the ribs hook on the pulley ribs before releasing the tensioner.
