Fluorescent Dye Injection

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. 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 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.

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.
