COMPRESSOR

General Precautions

INFOID:0000000005517180

CAUTION:

• Plug all openings to prevent moisture and foreign material from entering.
• Store it in the same way as it is when mounted on the car when the compressor is removed.
• Follow “Maintenance of Lubricant Quantity in Compressor” exactly when replacing or repairing

compressor. Refer to 

HA-25, "Maintenance of Lubricant Quantity"

.

• Keep friction surfaces between clutch and pulley clean. Wipe it off by using a waste moistened with

thinner if the surface is contaminated with lubricant.

• Turn the compressor shaft by hand more than five turns in both directions after compressor service

operation. This equally distributes lubricant inside the compressor. Let the engine idle and operate
the compressor for one hour after the compressor is installed.

• Apply voltage to the new compressor and check for normal operation after replacing the compressor

magnet clutch.

FLUORESCENT LEAK DETECTOR

FLUORESCENT LEAK DETECTOR

General Precautions

INFOID:0000000005517181

CAUTION:

• The A/C system contains a fluorescent leak detection dye used for locating refrigerant leakages. An

ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leakages.

• Always wear fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of

the fluorescent dye.

• The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST: J-41995).

The fluorescent dye leak detector should be used in conjunction with an electrical leak detector
(SST: J-41995) to pin-point refrigerant leakages.

• Read and follow all manufacturer operating instructions and precautions prior to performing work

for safety and customer satisfaction.

• A compressor shaft seal should not necessarily be repaired because of dye seepage. The compres-

sor shaft seal should only be repaired after confirming the leakage with an electrical leak detector
(SST: J-41995).

• Always remove any remaining dye from the leakage area after repairs are completed to avoid a mis-

diagnosis during future service.

• Never allow dye to come into contact with painted body panels or interior components. Immediately

clean with the approved dye cleaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.

• Never spray fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Never use more than one refrigerant dye bottle [1/4 ounce (7.4 cc)] per A/C system.
• Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Never use

HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C system, otherwise A/C system damage may result.

• The fluorescent properties of the dye remains for three or more years unless a compressor malfunc-

tion occurs.

IDENTIFICATION

NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.

IDENTIFICATION LABEL FOR VEHICLE

Vehicles with factory installed fluorescent dye have an identification label on the front side of hood.

Special Service Tool

INFOID:0000000005517182

The actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here.

HFC-134a (R-134a) Service Tool and Equipment

• Never mix HFC-134a (R-134a) refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/

or its lubricant.

• Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/

lubricant.

• Refrigerant container fittings, service hose fittings and service equipment fittings (equipment that handles

refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.

• Never use adapters that convert one size fitting to another. Refrigerant/lubricant contamination occurs and

compressor malfunction may result.
