Notice: Routine inspection of the drive belt may reveal cracks in the belt ribs. These cracks will not impair belt performance and therefore should not be considered a problem requiring belt replacement. However, the belt should be replaced if belt slipping occurs or if sections of the belt ribs are missing.

Important: The indicator on the movable portion of the tensioner must be within the tolerance marks on the stationary portion of the tensioner. Any reading outside of these marks indicates either a defective belt or tensioner.

1. Inspect the belt length on the drive belt tensioner for the proper installed length. If the tensioner pulley does not indicate the proper installed length, install a new drive belt.
2. Raise and suitably support the vehicle. Refer to SECTION 0A.
3. Rotate the drive belt tensioner downward off the serpentine drive belt using a offset wrench on the tensioner pulley bolt.
4. Remove the drive belt from the accessory pulleys.

1. Install the serpentine drive belt to the accessory pulleys.
2. Install the drive belt over the tensioner pulley by pulling down on the drive belt tensioner. Be sure that the drive belt is aligned into the proper grooves of the accessory drive pulleys.
3. Lower the vehicle.
