Fluorescent Dye Injection

WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Use only fluorescent dye approved by General Motors.

Not all of the fluorescent dyes are compatible with all air conditioning oils. Some types of dye decrease the oil viscosity or may chemically react with the oil.
GE-41447 A/C Tracer Dye-Box of 24 can be poured directly into a removed A/C component.

NOTE:

Do NOT overcharge the A/C system with dye.

If the A/C system has been repaired and oil is needed in the system, use either the GE-50744 R-1234yf PAG Oil Injection Hose or GE-50745 R-1234yf POE Oil Injection Hose.
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.
To prevent false diagnosis, thoroughly clean any residual dye from the service port with a rag and the approved GE-43872 Dye Cleaner.
