Maintenance of Oil Quantity in Compressor

INFOID:0000000001396443

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 ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COMPRESSOR

After replacing any of the following major components, add the correct amount of oil to the system.

Amount Of Oil To Be Added

*1: If refrigerant leak is small, no addition of oil is needed.

OIL

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.

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

3.

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

4.

Drain the oil from the new compressor into a separate, clean container.

5.

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.

6.

Measure an amount of new oil equal to the amount recovered during discharging. Add this oil to new com-
pressor through the suction port opening.

7.

If the liquid tank also needs to be replaced, add another 5 m  (0.2 US fl oz, 0.2 Imp fl oz.) of oil at this
time.
Add this 5 m  (0.2 US fl oz, 0.2 Imp fl oz.) of oil only when replacing the compressor.

SETTING OF SERVICE TOOLS AND EQUIPMENT

Discharging Refrigerant

WARNING:

Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Remove HFC-134a (R-134a) refrigerant from the A/C system using certified service equipment meeting
requirements of SAE J2210 HFC-134a (R-134a) recycling equipment or SAE J2201 HFC-134a (R-134a)
recovery equipment. If an accidental system discharge occurs, ventilate the work area before resum-
ing service. Additional health and safety information may be obtained from the refrigerant and oil man-
ufacturers.

Checking of Refrigerant Leaks

INFOID:0000000001396447

Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leak-
age, damage and corrosion. A/C oil leakage may indicate an area of refrigerant leakage. Allow extra inspec-
