Drive Belt: Service and Repair

DRIVE BELT REPLACEMENT

1. Check the drive belts for wear, cracks and fraying; replace if necessary.
2. Check the drive belt deflection by applying moderate pressure [98 Newton only, NOT N.m] { 10 kgf, 22 Ibf } midway between the pulleys.

Note: Measure the belt deflection between the specified pulleys. A belt is considered "New" if it has been used on a running engine for less than five minutes. Set the deflection specified below accordingly. Check the belt deflection when the engine is cold, or at least 30 minutes after the engine has stopped.





















3. If the deflection is not within specification, adjust it.

Drive belt tension check

Note: Belt tension can be checked in place of belt deflection. Belt tension can be measured between any two pulleys.






4. Check the drive belt tension with the tension gauge.

Adjustment

Caution: If a new belt is used, adjust the belt deflection at the midpoint of "New" belt specification. A belt is considered "New" if it has been used on a running engine for less than five minutes.






1. Alternator belt deflection
If necessary, loosen the alternator bolts and adjust the belt deflection by turning the adjusting nut.
Tightening torque:
(A): 38-51 N.m {3.8-5.3 kgf.m, 28-38 ft-Ibf}
(B): 19-25 N.m {1.9-2.6 kgf.m, 14-18 ft-Ibf}






2. P/S oil pump belt deflection
If necessary, loosen the locknut and adjust the belt deflection by turning the adjusting bolt.
Tightening torque: 38-51 N.m {3.8-5.3 kgf.m, 28-38 ft.lbf}






3. A/C compressor belt deflection
If necessary, loosen the A/C locknut and adjust the belt deflection by turning the adjusting bolt.
Tightening torque: 38-51 N.m {3.8-5.3 kgf.m, 28-38 ft.Ibf}
