WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Use only fluorescent dye approved by General Motors.

GE-41447 R-134A A/C Tracer Dye-Box of 24 can be poured directly into a removed A/C component.
GE-46297-12 Replacement Dye Cartridges is injected into the low side port using GE-46297 A/C Dye Injector Kit.

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.
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.

NOTE:

Do NOT overcharge the A/C system with dye. Use only one 7.39 ml (0.25 oz) charge.

To prevent false diagnosis, thoroughly clean any residual dye from the service port with a rag and the approved fluorescent dye cleaner GE-43872 Fluorescent Dye Cleaner.
