DRIVE BELT TENSION
DRIVE BELT TENSION INSPECTION
1. INSPECT DRIVE BELT'S INSTALLATION CONDITION
Check that drive belt fits properly in the ribbed grooves.
2. INSPECT DRIVE BELT TENSION
Check that the tension is within A range on the auto tensioner
scale.
If the tension is not within the A range on the scale, replace
the belt with a new one.
HINT: When replacing the drive belt with a new one, the belt's
tension should be within the B range on the belt tensioner
scale.

CONDENSER
ON±VEHICLE INSPECTION
1. INSPECT CONDENSER FINS FOR BLOCKAGE OR
DAMAGE
If fins are clogged, wash them with water and dry with com-
pressed air.
NOTICE: Be careful not to damage the fins.
If fins are bent, straighten them with a screwdriver or pliers.
2. INSPECT CONDENSER AND FITTING FOR LEAKAGE
Using a gas leak tester, check for leakage.
If there is leakage, check the tightening torque at the joints.
