WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Tools Required
- J 39400-A Halogen Leak Detector. See Special Tools .
- J 41447 R 134a A/C Tracer Dye-Box of 24. See Special Tools .
- J 42220 Universal 12V Leak Detection Lamp. See Special Tools .
- J 46297 A/C Dye Injector Kit. See Special Tools .
- J 46297-12 Replacement Dye Cartridges. See Special Tools .
IMPORTANT:
Saturn vehicles are now manufactured with fluorescent dye installed directly into the A/C system.
The preferred method of leak testing is with the use of fluorescent dye. J 41447 is the only fluorescent dye approved by Saturn. See Special Tools .
The fluorescent dye mixes and flows with the PAG oil throughout the refrigerant system.
Verifying some passive leaks may require using the J 39400-A , even though the A/C system contains fluorescent dye. See Special Tools .
The only time that adding additional fluorescent dye is required is after flushing the A/C system.
