Technicians can simply add a small amount of TP-3100 dye to the crankcase and allow it to circulate for several minutes. Wherever there is a leak, the dye escapes with the oil and accumulates at the site of each and every leak.
Scan the system with a high-intensity Tracerline ultraviolet or blue light lamp and the dye glows a bright yellow color to clearly reveal the exact location of all leaks - even small leaks undetected by other methods.
After the leaks have been repaired, technicians scan the system with the light again. If there is no glow, it means that all the leaks were fixed properly.
TP-3100 dye can remain safely in the system until the oil is changed, making it ideal for preventive maintenance. Periodic inspections with the lamp will detect future leaks before they can cause damage to the system.
