Checking System For Leaks Using The Fluorescent Leak Detector

WARNING: This page is about a different car, the 2002 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.

Check A/C system for leaks using the UV lamp and safety glasses (J-42220) in a low sunlight area (area without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indicates an evaporator core assembly (tubes, core or TXV) leak.
If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or cloth, then check the cloth with the UV lamp for dye residue.
Confirm any suspected leaks with an approved electronic refrigerant leak detector.
After the leak is repaired, remove any residual dye using dye cleaner (J-43872) or prevent future misdiagnosis.
Perform a system performance check and verify the leak repair with an approved electronic refrigerant leak detector.
