Water Pump/Generator Drive Belt Tension Inspection and Adjustment
1) Inspect belt for cracks, cuts, deformation, wear and cleanli-
ness. If it is necessary to replace belt, refer to “Water Pump/
Generator Drive Belt Removal and Installation” in this sec-
tion.
2) Check belt for tension. Belt is in proper tension when it
deflects the following specification under thumb pressure
(about 10 kg or 22 lb.).
Water pump / generator drive belt tension “a”
4.5 – 5.5 mm (0.18 – 0.22 in.) as deflection/10 kg (22 lbs)
3) If belt is too tight or too loose, adjust it to proper tension by
displacing generator position.
4) Tighten generator adjusting bolt (1) and pivot bolts (2) as
specified torque.
Tightening torque
Generator adjusting bolt (a): 23 N·m (2.3 kg-m, 17.0 lb-ft)
Generator pivot bolt (b): 50 N·m (5.0 kg-m, 36.0 lb-ft)
5) Connect negative cable at battery.
WARNING:
• Disconnect negative cable at battery before checking and adjusting belt tension.
• To help avoid danger of being burned, do not remove radiator cap while engine and radiator are still
hot. Scalding fluid and steam can be blown out under pressure if cap is taken off too soon.
NOTE:
When replacing belt with a new one, adjust belt tension
to 3 – 4 mm (0.12 – 0.16 in.).
