An accessory drivebelt, located at the front of the engine, is crucial for the operation of the engine and its components. It drives the alternator, power steering pump, water pump and air conditioning compressor on four-cylinder models, and the alternator and air conditioning compressor on V6 models. The belt should be inspected at regular intervals, but may not need replacement for over 100,000 miles. To check the belt, raise the front of the vehicle and remove the right-hand wheel and splash shield. Inspect the belt for cracks, separation, fraying, and glazing. Small cracks in the edges of the belt ribs are not unusual and do not necessarily require replacement. To replace the belt, disconnect the cable from the negative terminal of the battery, loosen the right front wheel lug nuts, raise the front of the vehicle and remove the right front wheel and splash shield. Note the routing of the drivebelt, then remove it from the pulleys. Install the new drivebelt onto the pulleys, making sure it is correctly seated, then release the tensioner. Install the splash shield and wheel, then lower the vehicle and tighten the lug nuts. The power steering pump drivebelt on V6 engines is a unique design called a stretchy belt, which provides tension without a mechanical tensioner. To replace this belt, disconnect the cable from the negative terminal of the battery, loosen the right front wheel lug nuts, raise the vehicle and remove the wheel and splash shield. Insert a flexible material under the belt at the pulley, rotate the engine, and pull the strap to force the belt from the pulley. Install the new belt, making sure it is properly positioned. The accessory drivebelt tensioner can be removed by detaching the bolts securing it to the engine block or timing chain cover, depending on the model. Installation is the reverse of removal.
