Precautions For Leak Detection Dye

Precautions For Leak Detection Dye
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.







IDENTIFICATION LABEL
Location: Underside of Hood.
Color:
With Factory Installed Flourenscent Dye: Green.
Without Factory Installed Flourenscent Dye: Blue.


Always wear fluorescence enhancing UV safety glasses to protect your eyes and enhance the visibility of the fluorescent dye.

A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).

Always remove and dye from the leak area after repairs are complete to avoid a misdiagnosis during a future service.

Do not 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.

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 R-134a and R12 A/C systems are different. Do not use R-134a leak detection dye in R-12 A/C system or R-12 leak detector dye in R-134a A/C systems or A/C system damage may result.

The fluorescent properties of the dye will remain for over three (3) years unless a compressor failure occurs.
