LEAK DETECTION DYE
LEAK DETECTION DYE
General Precautions
INFOID:0000000009718624
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.

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.
