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