Fluorescent Dye Injection

IMPORTANT:
- J 41447 is the only A/C leak detection dye approved by General Motors.
- Not all of the R-134a dyes are compatible with PAG oil. Some dyes 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.
- 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 any false diagnosis, thoroughly clean any residual dye from the service port with a rag and the approved fluorescent dye cleaner J 43872.
- The dye injection package contains a notice sticker. Complete the leak detection information and place the sticker near the charge label.
