Fluorescent Leak Detector

TOOLS REQUIRED
^ J 41447 R-134a Tracer Dye
^ J 41459 R-134a A/C Tracer Dye Injector
^ J 28428-E High Intensity Black Light

R-134a refrigerant is uniquely different from R-12 refrigerant used in the past and may require additional methods to detect leaks. The R-134a molecule is smaller than the R-12 molecule and can leak through smaller openings. R-134a does not contain chlorine, which the electronic leak detectors found easy to identify. The tracer dye method is meant to be used in conjunction with the electronic leak detector and will pinpoint smaller leaks undetected by using the electronic leak detector. R-134a tracer dye requires time. Depending upon the rate of leak, the leak may take up to 7 days to become visible.

IMPORTANT:
^ The J 41447 has been developed to be used only with R-134a equipped vehicles or vehicles that have been retrofitted from R-12 to R-134a.
^ Only J 41447 R-134a Tracer Dye is recommended for use in the R-134a system. Use of any other products may affect system reliability and cause premature compressor failure.
^ Use only a 1/4 ounce charge of tracer dye. Larger amounts may compromise the reliability of the A/C system.
^ After adding tracer dye, clean the service valves and surfaces of residual dye with GM Engine Degreaser GM P/N 1050436 or the equivalent, in order to prevent false diagnosis.
