Drive Belt Tension Check and Adjustment

Power Steering Oil Pump And A/C Compressor Drive Belt Tension Check





1. Check if the belt tension is within the standard value using one of the methods below





Standard Value


With your fingertip lightly tap the center of the belt between the pulleys in the location shown by the arrow in the illustration and then measure the belt vibration frequency.

NOTE: For information regarding the vibration frequency measurement method using the scan tool refer to Drive Belt; Alternator; Testing and Inspection.


Use a belt tension gauge to measure the belt tension.


Apply 98 N (22 lbs.) of pressure against the location between the pulleys shown by the arrow in the illustration and then measure the deflection.





2. If the tension or deflection is outside the standard value, adjust by the following procedure.
1. Loosen the tension pulley nut.
2. Adjust the belt deflection amount using the adjusting bolt.
3. Tighten the tension pulley nut.

CAUTION: Fix the power steering oil pump at the closest position to the vehicle front.
