Welcome to JA,
3.0L ENGINE-AIR CONDITIONER BELT
To remove and install the air conditioning compressor drive belt, first loosen the idler pulley lock nut, then turn the adjusting screw to raise or lower the idler pulley. The belt can then be removed from the crankshaft pulley, the A/C compressor pulley and the idler pulley. However, before the A/C drive belt can be removed from the vehicle, the serpentine belt must be removed also.
3.0L ENGINE-SERPENTINE BELT
See Figure 11
The Poly-V generator/power steering pump belt is provided with a dynamic tensioner to maintain proper belt tension. To remove or install the belt, release the tension by rotating the tensioner assembly clockwise, then remove the belt from the pulleys and extract from the vehicle. When installing the belt, make certain that the belt is securely set onto the pulleys (the grooves on the belt must be aligned with the grooves on the pulley).
3.3L AND 3.8L ENGINES-SERPENTINE BELT
See Figure 12
The Poly-V drive belt is provided with a dynamic tensioner to maintain proper belt tension. To remove or install this belt:
Raise the front of the vehicle and safely support on jackstands.
Remove the right front splash shield.
Release tension of the belt by rotating the tensioner assembly clockwise.
While holding the tensioner in the rotated position, remove the belt from the various pulleys-make sure to note the route that the belt takes before removal.
To install the belt, route it through the various pulleys except for the tensioner pulley. Once the belt is satisfactorily mounted on the pulleys, rotate the tensioner clockwise and slide the belt onto the tensioner pulley. Make certain that the belt is mounted so that the grooves in the belt are correctly aligned with the grooves in the pulleys.
Fig. 12: To remove the serpentine belt from the 3.3L and 3.8L engines, rotate the tensioner assembly clockwise
Install the right front splash shield to the underside of the vehicle.
Lower the vehicle back to the ground.
Start the engine and allow to idle for a few minutes. Shut the engine off and double check the placement of the belt on the pulleys.
