LUBRICANT
LUBRICANT
Maintenance of Lubricant QuantityINFOID:0000000003795916
The lubricant in the compressor circulates through the system the refrigerant. Add lubricant to compressor
when replacing any component or after a large refrigerant leakage occurred. It is important to maintain the
specified amount.
If lubricant quantity is not maintained properly, the following malfunctions may result:
 Lack of lubricant: May lead to a seized compressor.
 Excessive lubricant: Inadequate cooling (thermal exchange interference)
LUBRICANT
LUBRICANT RETURN OPERATION
Adjust the lubricant quantity according to the test group shown below.
1.CHECK LUBRICANT RETURN OPERATION
Can lubricant return operation be performed?
 A/C system works normally.
 There is no evidence of a large amount of lubricant leakage.
CAUTION:
Never perform the lubricant return operation if excessive lubricant leakage is detected.
Is it successful?
YES >> GO TO 2.
NO >> GO TO 3.
2.PERFORM LUBRICANT RETURN OPERATION
1. Start the engine, and set to the following conditions:
- Engine speed: Idling to 1,200 rpm
- A/C switch: ON
- Blower speed: Max. position
- Set temperature: FULL HOT
- Intake position: Recirculation (REC)
2. Perform lubricant return operation for approximately 10 minutes.
3. Stop the engine.
>> GO TO 3.
3.CHECK REPLACEMENT PART
Should the compressor be replaced?
YES >> Refer to HA-29, "Lubricant Adjusting Procedure for Compressor Replacement".
NO >> Refer to HA-28, "
Lubricant Adjusting Procedure for Components Replacement Except Compres-
sor".

FLUORESCENT LEAK DETECTOR
FLUORESCENT LEAK DETECTOR
InspectionINFOID:0000000003795981
CHECKING SYSTEM FOR LEAKAGES USING THE FLUORESCENT LEAK DETECTOR
1. Check A/C system for leakages using the UV lamp and safety goggles (SST: J-42220) in a low sunlight
area (area without windows preferable). Illuminate all components, fittings and lines. The dye appears as
a bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain open-
ing indicates an evaporator core assembly (tubes, core or expansion valve) leakage.
2. Use an adjustable mirror or wipe the area with a clean shop rag or cloth, with the UV lamp for dye residue
if the suspected area is difficult to see.
3. Remove any residual dye using dye cleaner (SST: J-43872) to prevent future misdiagnosis after the leak-
age is repaired.
4. Perform a system performance check and verify the leakage repair with an approved electrical leak detec-
tor.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This may also cause false readings
and may damage the detector.
DYE INJECTION
(This procedure is only necessary when recharging the system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.45 bar, 3.52 kg/cm
2, 50
psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (SST: J-41459).
3. Connect the injector tool to the A/C low-pressure side service valve.
4. Start the engine. Then switch A/C ON.
5. Inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye through the low-pressure service valve using dye
injector tool (SST: J-41459) (refer to the manufacture’s operating instructions) when the A/C operating
(compressor running).
6. Disconnect the injector tool from the service valve with the engine still running.
CAUTION:
Be careful when replacing the A/C system or a component, pour the dye directly into the open sys-
tem connection and proceed with the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leakage size, operating conditions and location of the leakage, it may take from minutes to days for the
dye to penetrate a leakage and become visible.
8. Attach a blue label if necessary.
