Leak Detection Dye

WARNING: This page is about a different car, the 2016 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.
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 eyes and enhance the visibility of the fluorescent dye.
  • The fluorescent dye leak detector is not a replacement for an electronic leak detector (SST: J - 41995). The fluorescent dye leak detector should be used in conjunction with an electronic leak detector (SST: J - 41995) to pin - point refrigerant leaks.
  • Read and follow all manufacture's operating instructions and precautions prior to performing the work for the purpose of safety and customer's satisfaction.
  • A compressor shaft seal should not necessarily be repaired because of dye seepage. The compressor shaft seal should only be repaired after confirming the leak with an electronic leak detector (SST: J - 41995).
  • Always remove any remaining dye from the leak area after repairs are completed to avoid a misdiagnosis during a future service.
  • Do not allow dye to come into contact with painted body panels or interior components. Clean immediately with the approved dye cleaner if dye is spilled. Fluorescent dye left on a surface for an extended period of time cannot be removed.
  • Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
  • Do not 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. Do not 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 remains for three or more years unless a compressor malfunction occurs.
NOTE:

Identification

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