INSPECTION
- CHECK EVAPORATOR FINS FOR BLOCKAGE If the fins are clogged, clean them with compressed air.
- CHECK FOR CRACKS AND SCRATCHES If necessary, repair or replace damaged parts.
- INSPECT THERMISTOR RESISTANCE (See «DTC 13: FRONT EVAPORATOR TEMPERATURE SENSOR CIRCUIT»(ref-227582-S39238469422006040600000) )
INSPECT AIR INLET SERVOMOTOR OPERATION (See DTC 42: AIR INLET DAMPER CONTROL SERVOMOTOR CIRCUIT )

- DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM HINT: At the time of the installation, refer to the following: Evacuate air from the refrigeration system. Charge the system with refrigerant and inspect for leakage of refrigerant. Specified amount: Single A/C: 750 +/- 50 g (26.45 +/- 1.76 oz.) Dual A/C: 1050 +/- 50 g (37.03 +/- 1.76 oz.)
- DISCONNECT 2 LIQUID TUBES FROM RECEIVER Remove the 2 bolts and disconnect both tubes. Torque: 5.4 N.m (55 kgf.cm, 48 in.lbf) NOTE: Cap the openings immediately to keep moisture or dirt out of the system. HINT: At the time of the installation, refer to the following: Lubricate 2 new O-rings with compressor oil and install them to the tubes.
- REMOVE RECEIVER Remove the 2 bolts and receiver. HINT: At the time of the installation, refer to the following: If the receiver is replaced, add compressor oil to the compressor. Add 20 cc (0.71 fl.oz.) Compressor oil: ND-OIL 8 or equivalent Remove the 2 bolts and holder.
- INSPECT CONDENSER FINS FOR BLOCKAGE OR DAMAGE If the fins are clogged, wash them with water and dry with compressed air. NOTE: Be careful not to damage the fins. If the fins are bent, straighten them with a screwdriver or pliers.
- INSPECT CONDENSER AND FITTINGS FOR LEAKAGE Using a gas leak detector, check for leakage of refrigerant. If there is leakage, check the tightening torque at the joints.

- DISCONNECT LIQUID TUBE AND DISCHARGE HOSE Remove the 2 bolts and disconnect both tube and hose. Torque: 5.4 N.m (5.5 kgf.cm, 48 in.lbf) NOTE: Cap the openings immediately to keep moisture or dirt out of the system. HINT: At the time of installation, refer to the following: Lubricate 2 new O-rings with compressor oil and install them to the tubes.
- REMOVE CONDENSER Remove the 2 bolts. Pull the condenser forward and then upward. HINT: At the time of installation, refer to the following: If the condenser is replaced, add compressor oil to the compressor. Add 40 to 50 cc (1.4 to 1.7 fl.oz.) Compressor oil: ND-OIL 8 or equivalent
- CHECK QUANTITY OF GAS DURING REFRIGERATION CYCLE
- SET MANIFOLD GAUGE SET (See «MANIFOLD GAUGE SET»(ref-227667-S33291989582006040600000) )
- RUN ENGINE Rear blower speed set at "HI" position A/C switch ON Rear temperature control set at 18.5° C (65° F) Run the engine at 1,500 RPM for at least 5 minutes. Then check that the high pressure reading is 1.9 to 2.1 MPa (19 to 21 kgf/cm 2 , 270 to 300 psi).
- CHECK EXPANSION VALVE If the expansion valve is faulty, the low pressure reading will drop to 0 kPa (0 kgf/cm 2 , 0 psi).
