According to Tracer, Dye-Lite TP-3100 fluorescent dye pinpoints engine oil, hydraulic fluid, lubrication fluid, compressor oil and gearbox oil leaks easily and efficiently.
To use, add a small amount of TP-3100 dye to the system and allow it to circulate for several minutes. Wherever there is a leak, Tracer says the dye escapes with the oil and accumulates at the site of each leak. The company then says to scan the system with a high-intensity Tracerline ultraviolet or blue light lamp and the dye glows a bright yellow color to reveal the exact location of all leaks.
After the leaks have been repaired, scan the system with the light again. If there is no glow, Tracer says that means that all the leaks were fixed properly.
TP-3100 dye can remain safely in the system until the oil is changed, making it suited for preventive maintenance. Periodic inspections with the lamp will detect future leaks before they can cause damage to the system.
