Drive Belt: Service and Repair

BELT REPLACEMENT OR ADJUSTMENT
Belt tension is adjusted at the power steering pump bracket and idler pulley assembly.
1. Disconnect negative battery cable from battery.





2. Loosen idler pulley bolt at the power steering bracket (Fig. 4).
3. Loosen adjusting bolt until belt can be removed from pulleys.
4. Remove belt.

INSTALLATION OR ADJUSTMENT
1. Check condition of all pulleys.








CAUTION: When installing the serpentine accessory drive belt, the belt MUST be routed correctly. If not, the engine may overheat due to the water pump rotating in the wrong direction. Refer to (Fig. 2) (Fig.3) for correct belt routing.

2. Install new belt.
3. Using serpentine belt tension gauge, tighten adjusting bolt until belt reaches proper tension.
4. After belt is tensioned correctly, tighten idler pulley bolt to 47 Nm (35 ft. lbs.) (Fig. 4).
5. After idler pulley has been tightened into position, recheck belt tension. Adjust if necessary.
Correct drive belt tension is required to ensure optimum performance of the belt driven engine accessories. There are different types of adjustment gauges for checking either a serpentine or a V-type belt. Refer to the instructions supplied with the gauge. Use the correct gauge when checking belt tension. Place gauge in the middle of the section of belt being tested (between two pulleys) to check tension. Do not allow the gauge (or gauge adapter) to contact anything but the belt.
