LEAK DETECTION DYE

LEAK DETECTION DYE

General Precautions

INFOID:0000000005514525

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 the eyes and enhance the visibil-

ity 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:0000000005514526

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.
