Drive Belt: Adjustments
COOLING FAN BELT TENSION CHECK AND ADJUSTMENTWARNING: Disconnect negative cable at battery before checking and adjusting belt tension
FOR G16 AND H25 ENGINES
1. Inspect belt for cracks, cuts, deformation, wear and cleanliness. If so, replace belt.
2. Check belt for tension. Belt is in proper tension when it deflects 6 to 8 mm (0.24 - 0.32 inch) under thumb pressure (about 10 kg or 22 lb.).
Cooling fan belt tension "a" (as deflection/10 kg (22 lbs.))
For G16 engine: 6 - 8 mm (0.24 - 0.32 inch)
For H25 engine: 9 - 11 mm (0.35 - 0.43 inch)
NOTE: When replacing belt with a new one, adjust belt tension to 5 - 7 mm (0.20 - 0.27 inch) (G16 engine) or 7 - 9 mm (0.27 - 0.35 inch) (H25 engine).
3. If belt is too tight or too loose, adjust it to proper tension by displacing generator position.
4. Tighten generator adjusting bolt and pivot bolt.
5. Connect negative (-) cable at battery.
FOR J20 ENGINE
1. Inspect belt for cracks, cuts, deformation, wear and cleanliness. If so, replace belt.
2. Check belt for tension. Belt is in proper tension when it deflects 5 to 7 mm (0.20 - 0.27 inch) under thumb pressure (about 10 kg or 22 lb.).
Cooling fan belt tension "a" (as deflection/10 kg (22 lbs.))
For J20 engine: 5 - 7 mm (0.20 - 0.27 inch)
NOTE: When replacing belt with a new one, adjust belt tension to 4 - 5 mm (0.16 - 0.20 inch).
3. If belt is too tight or too loose, adjust it as follows:
a. Loosen adjusting bolt and pivot bolt.
b. Tighten adjusting bolt during keeping fan belt in proper tension by tightening tension bolt with wrench as shown in the figure.
c. Tighten adjusting bolt and pivot bolt to specified torque.
Tightening torque
Cooling fan pulley adjusting bolt (for J20 engine) (a): 45 Nm (4.5 kg-m, 32.5 ft. lbs.)
Cooling fan pulley pivot bolt (for J20 engine) (a): 45 Nm (4.5 kg-m, 32.5 ft. lbs.)
4. Connect negative (-) cable at battery.
