DRIVE BELTS TENSION ADJUSTMENT
Check that the belts are not damaged and fit properly into the pulley grooves.

CAUTION
When installing the V-ribbed belt, check that the Vribs are properly aligned.
If noise or slippage is detected, check the belt for wear, damage, or breakage on the pulley contact surface, and check the pulley for scoring. Also check for the proper belt deflection measurement.
Apply 100 N (22 Ibs.) force to the belt back midway between the pulleys as shown in the illustration, measure the amount of deflection with a tension gauge.
Standard value for air conditioner compressor (2.4L)

50 ± 5



Standard value for air conditioner compressor (2.5L)
The drive belt tension is adjusted automatically by autotensioner.


NOTE
The belt tension must be measured between the specified pulleys. When a new belt is installed, adjust the tension to the center of the standard range indicated under "New." Let the engine idle for 5 minutes or more, and check the standard value indicated under "Inspection." When adjusting a used belt or a newly installed belt after 5 minutes or more of operation, refer to the standard value indicated under "Used." Refer to the standard value indicated under "Inspection" for periodic inspections.

Adjustment (2.4L Engine)

Loosen the tension pulley fixing bolt A.
Adjust the belt deflection with adjustment bolt B.
Tighten the fixing bolt A.
Re-check the belt deflection and re-adjust, if necessary.
NOTE
Before re-checking, crank the engine one or more revolutions.

Adjustment (2.5L Engine)

If the mean indicator is positioned over the max. position, replace the drive belt.
When replacing the drive belt, must position the mean indicator between min. position and max. position.
Type A tension gauge

Do not let the dial section of the tension gauge contact other objects during measurement.


Type B tension gauge
When measuring, turn the reset button in the direction of the arrow to set the gauge needle to the RESET position.

When the tension gauge is removed from the belt, the needle will still indicate the tension. Read the tension after removing the gauge
