LEAK DETECTION DYE

LEAK DETECTION DYE

General Precautions

INFOID:0000000001093899

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:0000000001093900

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.
