ON-VEHICLE INSPECTION

INSPECT W/RECEIVER CONDENSER ASSY

(a) If a fin of the w/receiver condenser assy is dirty, clean it with water and dry it with compressor air.

NOTICE:

Do not damage the fin of the w/receiver condenser assy.

(b) If a fin of the w/receiver condenser assy is bent, make it straight using a screwdriver or pliers.

INSPECT W/RECEIVER CONDENSER ASSY FOR LEAKAGE OF REFRIGERANT

(a) Using a halogen leak detector, check pipe joints for gas leakage.

(b) If gas leakage is detected in a joint, check the torque of the joint.
