Always wear special goggles that protect your eyes and allow you to better see the fluorescent dye.
This leak detection method does not replace the use of an electrical leak detector (special device). Fluorescent dye leak detection should be done in conjunction with an electrical refrigerant leak detector test (special device) to determine the leak point.
For safety and quality assurance purposes, read all manufacturer's operating instructions and safety precautions before starting work.
The compressor shaft seal does not need to be repaired when painted with fluorescent dye. The compressor shaft seal must only be replaced if a leak is detected using an electrical leak detector (SST).
Always remove traces of dye from a leak after repair to prevent future diagnostic errors.
Do not allow the dye to come into contact with painted body panels and interior parts. In case of contact with dye, immediately clean the stained area with an approved cleaner. Fluorescent dye left on the surface for a long time cannot be removed.
Do not allow fluorescent dye cleaner to come into contact with hot surfaces (engine exhaust manifold, etc.).
Do not charge more than one bottle of refrigerant dye (1/4 oz / 7.4 cm3) to one air conditioning system.
HFC134a Leak Detection Dyes (R134a) and CFC12 (R-12) differ from each other. Do not use leak detection dye for HFC134a system (R134a) in CFC12 system (R-12) and vice versa. This may damage the system.
The properties of the fluorescent dye in leaks can be maintained for more than three years, in the absence of a compressor malfunction.
Note.
- Vehicles filled with fluorescent dye at the factory have a green decal. Vehicles not filled with fluorescent dye at the factory have a blue decal.
- On vehicles factory filled with fluorescent dye, the identification plate is located on the front of the hood.
