Description

MAINTENANCE OF OIL LEVEL

The compressor oil is circulating in the system together with the refrigerant. It is necessary to fill compressor

with oil when replacing A/C system parts or when a large amount of refrigerant leak is detected. It is important

to always maintain oil level within the specified level or otherwise the following conditions may occur:

• Insufficient oil amount: Stuck compressor

• Excessive oil amount: Insufficient cooling (caused by insufficient heat exchange)

Inspection

INFOID:0000000011279486

If a compressor is malfunctioning (internal noise, insufficient cooling), check the compressor oil.

1.

COMPRESSOR OIL JUDGMENT

1. Remove the compressor. Refer to 

HA-29, "Removal and Installation"

.

2. Sample compressor oil and judge below according to the figure.

Judgement result 1>>Replace compressor only.

Judgement result 2>>Replace compressor and condenser (includes liquid tank).

Perform Oil Return Operation

INFOID:0000000011279487

CAUTION:

If a large amount of refrigerant or oil leak is detected, do not perform oil return operation.
1. Start the engine and set to the following conditions:

• Engine speed: Idling to 1,200 rpm

• A/C switch: ON

• Fan (blower) speed: Maximum speed set

• Intake door position: Recirculation

• Temperature setting: Full cold

2. Perform oil return operation for approximately 10 minutes.
3. Stop the engine.
4. Oil return operation is complete.

Oil Adjusting Procedure for Components Replacement Except Compressor

INFOID:0000000011279488

Fill with oil for the amount that is calculated according to the following conditions.
Example: Oil amount to be added when replacing evaporator [m  (US fl oz, Imp fl oz)] = 75 (2.5, 2.6) +

Oil Adjusting Procedure for Compressor Replacement

INFOID:0000000011279489

1. Before connecting recovery/recycling equipment to vehicle, check recovery/recycling equipment gauges.

No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.

2. Connect recovery/recycling equipment to vehicle. Confirm refrigerant purity in supply tank using recovery/

recycling equipment and refrigerant identifier. If NG, refer to 

HA-4, "Precautions For Refrigerant System

Service"

.

3. Confirm refrigerant purity in vehicle A/C system using recovery/recycling equipment and refrigerant identi-

fier. If NG, refer to 

HA-4, "Precautions For Refrigerant System Service"

.

4. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure oil discharged into the

recovery/recycling equipment.

5. Drain the oil from the “old” (removed) compressor into a graduated container and recover the amount of

oil drained.

6. Drain the oil from the “new” compressor into a separate, clean container.
7. Measure an amount of new oil installed equal to amount drained from “old” compressor. Add this oil to

“new” compressor through the suction port opening.

PERFORMANCE TEST

Inspection

INFOID:0000000011279490

INSPECTION PROCEDURE

1. Connect recovery/recycling/recharging equipment (for HFC-134a) or manifold gauge.
2. Start the engine, and set to the following condition.

Test condition

3. Maintain test condition until A/C system becomes stable. (Approximately 10 minutes)
4. Check that test results of “recirculating-to-discharge air temperature” and “ambient air temperature-to-

operating pressure” are within the specified value.

5. When test results are within the specified value, inspection is complete.

If any of test result is out of the specified value, perform diagnosis by gauge pressure. Refer to 

HA-17,

"Symptom Table"
