Drive Belt Inspection and Adjustment

Special Tools Required
^ Belt tension gauge 07JGG-001010A

Belt Tension Gauge Method
Inspection





1. Attach the belt tension gauge to the belt and measure the tension. Follow the gauge manufacturer's instructions. If the belt is worn or damaged, replace it. If the belt needs adjustment, go to step 2.
Tension:
Used Belt: 290 - 440 N (30 - 45 kgf, 66 - 99 lbs.)
New Belt: 740 - 880 N (75 - 90 kgf, 170 - 200 lbs.)

Adjustment





2. Loosen the idler pulley center nut (A).
3. Turn the adjusting bolt (B) to obtain the proper belt tension, then retighten the idler pulley center nut.
4. Recheck the belt tension.
5. If you installed a new belt, run the engine for 5 minutes, then readjust the belt to the used belt specification.

Deflection Method
Inspection





1. Apply a force of 98 N (10 kgf, 22 lbs.), and measure the deflection at the mid point (A) between the A/C compressor and idler pulley. If the belt is worn or damaged, replace it. If the belt needs adjustment, go to step 2.
Deflection:
Used Belt: 12.5 - 16.0 mm (0.49 - 0.63 inch)
New Belt: 7.0 - 9.5 mm (0.28 - 0.37 inch)

Adjustment





2. Loosen the idler pulley center nut (A).
3. Turn the adjusting bolt (B) to obtain the proper belt tension, then retighten the idler pulley center nut.
4. Recheck the belt tension.
5. If you installed a new belt, run the engine for 5 minutes, then readjust the belt to the used belt specification.
