Fluorescent Dye Injection

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, 2003 Chevrolet TrailBlazer, and 2002 Oldsmobile Bravada. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: J41447 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.
