The following procedure should be used when replacing or adjusting the alternator/water pump belt (Figure 1).

1. Loosen alternator pivot bolt "E".

2. Loosen adjusting lock nut "D".

3. If belt replacement is necessary, loosen adjusting bolt "F". (To replace belt, first remove air pump belt. Refer to service manual procedure for "Air Pump Belt.")

4. Remove old belt and/or install new belt.

5. Tighten adjusting screw "F" until belt tension reaches:

Gauge Deflection

New Belt 95 lbs.* 1/4 in. (5.892 mm)
Used Belt** 70 lbs.* 5/16 in. (7.366 mm)
6. Torque pivot bolt "E" to 40 foot pounds (54 N-m).

7. Torque adjusting lock nut "D" to 250 inch pounds (28 N-m).

New Belt 115 lbs.* 3/16 in. (4.878 mm)
Used Belt** 90 lbs.* 1/4 in. (5.892 mm)
