1. From top of the vehicle, loosen locking nuts (1) and (2) (Fig. 4).
2. From under the vehicle, loosen the pivot bolt (3). Loosen adjusting bolt (4) until belt can be removed.

CLEANING
Clean all foreign debris from belt pulley grooves. The belt pulleys must be free of oil, grease, and coolants before installing the drive belt.

INSPECTION
Belt replacement under any or all of the following conditions is required:
- Excessive wear
- Frayed cords
- Severe glazing

Fig. 11 Drive Belt Inspection:

Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 11).

NOTE: Do not use any type of belt dressing or restorer on Poly-V Belts.

INSTALLATION

Fig. 12 ACCESSORY DRIVE BELTS - 2.4L:

1. Install belt onto all pulleys except for the crankshaft (Fig. 12).
2. Rotate belt tensioner clockwise until belt can be installed onto the crankshaft pulley (Fig. 3). Slowly release belt tensioner.
3. Verify belt is properly routed and engaged on all pulleys (Fig. 12).
4. Install drive belt shield (Fig. 5) and lower vehicle.

POWER STEERING PUMP

Fig. 13 Belt Routing - 2.4L:

1. Install belt over crankshaft and power steering pump pulleys (Fig. 12) and (Fig. 13).
2. Apply an initial snug torque to pivot bolt (3) and front locking nut (2) (Fig. 4).
3. Tighten adjusting bolt (4) until proper belt tension is obtained (Fig. 4).
4. Tighten pivot bolt (3) and front locking nut (2) to 54 Nm (40 ft. lbs.) (Fig. 4).
5. Tighten rear locking nut (1) to 54 Nm (40 ft. lbs.) (Fig. 4).

ADJUSTMENTS
Satisfactory performance of the belt driven accessories depends on proper belt tension. Belt tensioning should be performed with the aid of Special Tool 7198. Because of space limitations in the engine compartment, the use of this gauge may be restricted. Raise the vehicle on a hoist and the remove the splash shield to gain access to the drive belts, if necessary. Adjust belt tension for either a New or Used belt.
