Water Pump and Generator Drive Belt
Water Pump and Generator Drive Belt Inspection and Adjustment1. Disconnect negative cable at battery.
2. Inspect belt for cracks, cuts, deformation, wear and cleanliness. If it is necessary to replace belt, refer to Water Pump and Generator Drive Belt Removal and Installation.
3. Check belt for tension. Belt is in proper tens ion when it deflects the following specification under thumb pressure (about 10 kg or 22 lb.).
Water pump / generator drive belt tension
"a": 9.0 - 10.0 mm (0.35 - 0.39 in.) as deflection / 10 kg (22 lbs)
NOTE:
When replacing belt with a new one, adjust belt tension to 7.5 - 8.5 mm (0.29 - 0.33 in.).
4. If belt is too tight or too loose, adjust it to proper tension by displacing tension pulley position.
5. To adjust belt tension, loosen tension pulley bolt and (1) tension pulley ad justing bolt (2) and then displace tension pulley position.
6. Tighten tension pulley bolt (1) and tension pulley adjusting bolt (2) to specified torque.
Tightening torque
Tension pulley bolt a: 25 Nm (2.5 kg-m, 18.0 lb-ft)
Tension pulley adjusting bolt b: 25 Nm (2.5 kg-m, 18.0 lb-ft)
