Air Conditioner 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 finger tip lightly tap the center of the belt between the pulleys in the location shown by the arrow (a) or (b) 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 (a) or (b) 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 tension pulley fixing bolt A.
2. Adjust belt tension with adjusting bolt B.
3. Tighten fixing nut A.
Tightening torque: 23 - 26 Nm (17 - 20 ft. lbs.)
4. Check the belt deflection amount and readjust if necessary.

CAUTION: This check should be carried out after turning the crankshaft one full rotation or more in the forward direction (to the right).
