Universal Dye-Lite™ Engine Coolant and Auto Body Leak Check Dye by Tracer Products®. TP-3900 fluorescent dye quickly finds leaks in radiators, hoses, water pumps and fittings. Just add 1 oz of the dye to a cooling system and allow it to circulate. Wherever the coolant leaks out, so does the dye, which remains at the site of each and every leak. When the system is scanned with a Tracerline® ultraviolet or blue light inspection lamp, the dye glows a bright green showing the exact location of all leaks. In addition to locating coolant leaks, TP-3900 is ideal for pinpointing wind and water leaks. Simply mix the dye in proper dilution with water and spray suspect leak sites outside the vehicle using the TracerJet™ spray gun. Then check the inside of the vehicle for leakthrough with a Tracerline® inspection lamp.
