2. Cooling fan belt installation
1) Install the cooling fan belt to the following parts.
- Fan pulley
- Generator
- Crankshaft pulley
Legend
- Adjust bolt
- Cooling fan belt
- Lock nut
3. A/C compressor drive belt installation
1) Install the A/C compressor drive belt to the following parts.
- Tension pulley
- A/C compressor
- Crankshaft pulley
Legend
- Lock nut
- Adjust bolt
- A/C compressor drive belt
4. Cooling fan belt adjustment
When installing a new belt, initial stretching of the belt occurs.
In addition, when reusing the belt, the belt needs to be fitted to the pulley groove.
After fitting the cooling fan belt, readjust the cooling fan belt tension.
1) Loosen the tension pulley lock nut using a wrench.
2) Adjust the cooling fan belt tension by turning the adjust bolt.
Note
- The standard amount of deflection shown is the value obtained when the standard pressure is applied to the midpoint of the fan pulley and generator.
Standard: 98 N { 10.0 kg / 22 lb }
Caution
- Accurately adjust the tension as there is a possibility the service life of the belt may be shortened or belt squeal may be generated if the tension is not within the appropriate range.
- Use a sonic tension meter to verify accurate tension adjustment.

3) Tighten the tension pulley lock nut to the specified torque.
Tightening torque: 41 N・m { 4.2 kgf・m / 30 lb・ft }
5. A/C compressor drive belt adjustment
When installing a new belt, initial stretching of the belt occurs.
In addition, when reusing the belt, the belt needs to be fitted to the pulley groove.
After fitting the A/C compressor drive belt, adjust the tension of the A/C compressor drive belt again.
1) Loosen the tension pulley lock nut.
2) Turn the tension pulley adjust bolt to adjust the tension.
Note
- The standard deflection shown is the value obtained when the specified load is applied to the measurement point of the A/C compressor drive belt.
98 N { 10.0 kg / 22 lb } Load
Caution
- Accurately adjust the tension as there is a possibility the service life of the belt may be shortened or belt squeal may be generated if the tension is not within the appropriate range.
- Use a sonic tension meter to verify accurate tension adjustment.
| Adjustment conditions |
Deflection |
Vibration frequency |
| When new |
12.5 to 16.5 mm { 0.49 to 0.65 in } |
92 to 112 Hz |
| Reused |
16.5 to 19.1 mm { 0.65 to 0.75 in } |
79 to 91 Hz |
