Maintenance of Oil Quantity in CompressorEJS00579
The oil in the compressor circulates through the system with the refrigerant. Add oil to compressor when
replacing any component or after a large refrigerant leakage occurred. It is important to maintain the specified
amount.
If oil quantity is not maintained properly, the following malfunctions may result:

Lack of oil: May lead to a seized compressor.

Excessive oil: Inadequate cooling (thermal exchange interference)
OIL
OIL RETURN OPERATION
Adjust the oil quantity according to the test group shown below.
1. CHECK OIL RETURN OPERATION
Can oil return operation be performed?

A/C system works properly.

There is no evidence of a large amount of oil leakage.
CAUTION:
If excessive oil leakage is noted, do not perform the oil return operation.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. PERFORM OIL RETURN OPERATION, PROCEEDING AS FOLLOWS
1. Start engine, and set the following conditions:
–Engine speed: Idling to 1,200 rpm
–A/C blower switch: ON
–Blower speed: Max. position
–Temp. control: Optional [Set so that intake air temperature is 25° to 30°C (77° to 86° F)].
–Intake position: Recirculation (REC)
2. Perform oil return operation for about 10 minutes.
3. Stop engine.
>> GO TO 3.
3. CHECK REPLACEMENT PART
Should the compressor be replaced?
YES >> GO TO MTC-19, "OIL ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT" .
NO >> GO TO MTC-19, "

Removal and Installation of CompressorEJS0058F
REMOVAL
1. Use the recovery/recycling equipment to evacuate the refrigerant.
2. Remove the two engine undercovers, using power tools.
3. Remove low-pressure flexible hose nut (A) and high-pressure
flexible hose bolt (B) from compressor.
CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
NOTE:
Type 1 shown, type 2 is similar.
4. Remove A/C compressor belt. Refer to EM-13, "
DRIVE BELTS"
.
5. Disconnect compressor connector (C).

6. Remove bolts (A) from compressor (1), using power tools.
7. Remove compressor (1) downward from the engine compart-
ment.
INSPECTION FOR CLUTCH DISC TO PULLEY CLEARANCE
1. Check the clearance around the entire periphery of the clutch disc.

Measure the clearance for the type 1 compressor as shown.

Measure the clearance for the type 2 compressor as shown.
2. If specified clearance is not obtained, replace compressor.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:

Replace O-rings of low-pressure flexible hose and high-pressure flexible hose with a new ones,
and apply compressor oil when installing.

When recharging refrigerant, check for leaks.
