Fluorescent Dye Injection

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Important: J 41447 is the only A/C leak detection dye approved by General Motors.

Not all of the fluorescent dyes are compatible with PAG oil.
Some types of dye decrease the oil viscosity or may chemically react with the oil.
R-134a leak detection dye requires time to work. Depending upon the leak rate, a leak may not become visible for between 15 minutes and 7 days.

Important: Do NOT overcharge the A/C system with dye. This may cause reliability problems. Use only one 7.39 ml (0.25 oz) charge bottle of J 41447 .

With the A/C system charged, add J 41447 to the A/C system using J 41459. Follow the instructions provided with J 41459 .
To prevent false diagnosis, thoroughly clean any residual dye from the service port with a rag and the approved fluorescent dye cleaner J 43872 .
