General Precautions

INFOID:0000000001093770

CAUTION:

• Plug all openings to prevent moisture and foreign matter from entering.
• When the compressor is removed, store it in the same way at it is when mounted on the car.
• When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compressor”

exactly. Refer to

HA-27, "Adjustment"

.

• Keep friction surfaces between clutch and pulley clean. If the surface is contaminated with lubricant,

wipe it off by using a clean waste cloth moistened with thinner.

• After compressor service operation, turn the compressor shaft by hand more than five turns in both

directions. This will equally distribute lubricant inside the compressor. After the compressor is
installed, let the engine idle and operate the compressor for one hour.

• After replacing the compressor magnet clutch, apply voltage to the new one and check for normal

operation.

LEAK DETECTION DYE

General Precautions

INFOID:0000000001093771

CAUTION:

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

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

• Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visi-

bility 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 leaks.

• For the purpose of safety and customer’s satisfaction, read and follow all manufacture’s operating

manuals and precautions prior to performing the work.

• 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 leak with an electrical leak detector (SST:
J-41995).

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

nosis during a future service.

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

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

• Never spray the 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, or A/C system damage may result.

• The fluorescent properties of the dye will remain for three years or a little over unless a compressor

malfunction 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 the identification label on the front side of hood.

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

INFOID:0000000001093772

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/lubri-
cant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which 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.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor malfunction will result.
