Refrigerant Leak Testing
Note. These vehicles are not now manufactured with fluorescent dye installed directly into the air conditioning (A/C) system. Therefore, if refrigerant leak testing is required, add florescent dye into the air conditioning (A/C) system.
The fluorescent dye mixes and flows with the polyalkylene glycol (PAG) oil throughout the refrigerant system.
Verifying some passive leaks may require using the GE-39400-A detector , even though the A/C system contains fluorescent dye.
