  • Specifically designed for air conditioning systems using PAG oil
  • Quality formulation is thermally stable to maintain PAG lubricant viscosity
  • Highly fluorescent dye assists with visual leak detection to eliminate guess work
  • 25 oz. Part No. 15-120 12346287


If I modified my air conditioning system to a different refrigerant (i.e. R-12 to R-134a or R-1234yf), should I use tracer oil for the old system specifications?

  • No, the tracer material used should be compatible with the fluids/ materials used in the modified system.

Can I use fluorescent tracer dye for leak detection?

  • Yes, tracer dye is a great tool for leak detection. The dye will be found in the area where the leak is present.

Do I need to flush the system after using fluorescent tracer dye?

  • No, tracer dye can remain in the system after the work has been completed.

Do ACDelco Tracer/Dye products always require a special applicator?

  • No, most tracer dyes can be easily added to the system reservoir. However, dyes for AC systems will have to be added using special tools to prevent the further loss of refrigerant when looking for a leak.
