*: No addition of lubricant is needed if the refrigerant leakage is small.

Lubricant Adjusting Procedure for Compressor Replacement INFOID:0000000003795918

1. Check recovery/recycling recharging equipment gauges before connecting recovery/recycling recharging
equipment to vehicle. No refrigerant pressure should be displayed. Recover refrigerant from the equip-
ment lines if NG.

2. Discharge refrigerant into the recovery/recycling recharging equipment. Measure lubricant discharged into
the recovery/recycling recharging equipment.

3. Drain the lubricant from the old (removed) compressor into a graduated container and recover the amount
of lubricant drained.

4. Drain the lubricant from the new compressor into a separate. Then clean container.
5. Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this

lubricant to new compressor through the suction port opening.
6. Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant

to new compressor through the suction port opening.
7. Add another 5 m (0.2 Imp fl oz.) of lubricant at this time if the liquid tank also needs to be replaced.

Do not add this 5 m (0.2 Imp fl oz.) of lubricant when replacing the compressor only.

< ON-VEHICLE MAINTENANCE >

REFRIGERATION SYSTEM

Inspection INFOID:0000000003795977

1.CHECK BLOWER MOTOR OPERATION
Check blower motor operation. Refer to the following.
• HAC-68, "Component Function Check" (WITHOUT 7 INCH DISPLAY)
• HAC-193, "Component Function Check" (WITH 7 INCH DISPLAY)
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace the parts according to the inspection results.

2.CHECK COMPRESSOR OPERATION
Check compressor operation. Refer to the following.
• HAC-72, "Component Function Check" (WITHOUT 7 INCH DISPLAY)
• HAC-197, "Component Function Check" (WITH 7 INCH DISPLAY)
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace the parts according to the inspection results.

3.CHECK REFRIGERANT CYCLE PRESSURE
Connect recovery/recycling recharging equipment to the vehicle and perform the diagnosis with the gauge
pressure. Refer to HA-8, "Trouble Diagnosis For Unusual Pressure".
Is the inspection result normal?
YES >> Perform the performance test. Refer to HA-30, "Performance Chart".
NO >> Repair or replace the parts according to the inspection results.

Performance Chart INFOID:0000000003795978

TEST CONDITION

Testing must be performed as per the following:

EXPANSION VALVE

< ON-VEHICLE REPAIR >

Removal and Installation INFOID:0000000003795857

REMOVAL
1. Use refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove mounting bolt (A), and then disconnect low-pressure

pipe (1) and high-pressure pipe (2) from expansion valve.
CAUTION:
Cap or wrap the joint of the A/C piping and expansion valve
with suitable material such as vinyl tape to avoid the entry
of air.

3. Remove mounting bolts (A), and then remove the expansion
valve (1).
CAUTION:
Cap or wrap the joint of the A/C piping and expansion valve
with suitable material such as vinyl tape to avoid the entry
of air.

INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
• Replace O-rings with new ones. Then apply compressor oil to them when installing.
• Check for leakages when recharging refrigerant.
