pimp92sc400 Posted June 19, 2006 Share Posted June 19, 2006 you can have dye put in and then they will use a blacklight to find a leak Quote Link to comment Share on other sites More sharing options...
monarch Posted June 19, 2006 Share Posted June 19, 2006 Use of dyes is not recommended by Toyota because Toyota considers dyes to be a system contaminant that could degrade long term system reliability / durability. Toyota has always recommended use of an electronic refrigerant leak detector or (in the old days) a halide torch leak detector. Dealers and most AC shops have an electronic leak detector. An easy way to prevent refrigerant leaks from ever developing is to simply run the AC system for at least 30 seconds and preferably for 5 minutes or more once every week or two throughout the year, including the winter months.

GrnHrnt Posted June 20, 2006 Share Posted June 20, 2006 Techniques known only to the ancients: Look for an oily dirt accumulation any place on the refrigerant piping and components. Wherever Freon is leaking out, it is carrying compressor oil out with it. The oil attracts and holds dirt at the leak point. Quote Link to comment Share on other sites More sharing options...
