These drivebelts, which are situated in front of the engine, are very important for the operation of the vehicle and therefore should be checked periodically and realigned since they are prone to a total failure after sometime. All models employ the single serpentine belt which does not need to be adjusted due to a provision of an automatic tensioner. To check the drivebelt, switch off the engine and then open the bonnet and use a torchlight checking for severed core, peeling of adhesive rubber or check for cracks at the ribs of the belt. Same to fraying and glazing, and if there are signs of it, then it is high time to replace the belt. For replacement, always carry belt along with you so that you can tell the exact belt that you want during purchasing a new belt. Lose the lug nuts of the right front wheel, safely jack up the car using jackstands, remove the right front wheel and inner fender splash shield. By use of a breaker bar or ratchet, the tensioner has to be turned to an anticlockwise position in order to removing the drivebelt from the pulleys in a way that the new belt is correctly positioned in between the pulleys. For a 3.0L V6, first, the air intake duct assembly is disconnected, the car is then lifted and supported on jackstands, the engine is then lifted to remove the right engine mount and its bracket, tension is then released on the drivebelt and the belt is then removed. For a 3.5L V6 engine it is exactly the same, the difference is that the emphasis is put on the air intake duct-less tension to slip off the belt. While replacing the tensioner, one need to ensure that the key is out of the ignition, then one has to take off the drivebelt, withdraw the tensioner mounting fasteners and then fix the new tensioner by following the above procedures in the reversal manner by very tight tightening the fasteners to a particular torque.
