Special Tools
- J 39400-A: Halogen Leak Detector
- J 41447: R 134a A/C Tracer Dye-Box of 24
- J 42220: Universal 12V Leak Detection Lamp
- J 46297: A/C Dye Injector Kit
- J 46297-12: Replacement Dye Cartridges
NOTE:
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: R 134a A/C Tracer Dye is the only fluorescent dye approved by Saturn.
The fluorescent dye mixes and flows with the PAG oil throughout the refrigerant system.
Verifying some passive leaks may require using theJ 39400-A: Halogen Leak Detector, even though the A/C system contains fluorescent dye.
The only time that adding additional fluorescent dye is required is after flushing the A/C system.
