Refrigerant Leak Testing

WARNING: This page is about a different car, the 2003 GMC Sonoma, 2003 GMC Jimmy, 2003 Chevrolet S10 Pickup, and 2003 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.

Important:  General Motors passenger cars are now manufactured with fluorescent dye installed in the A/C system.

The preferred method of leak testing is the use of fluorescent dye. J 41447  is the only dye approved by General Motors. Follow the Fluorescent Dye Injection procedure for vehicles that do not already contain the fluorescent dye.
