Approved by General Motors, this specially formulated dye will not affect the color of extended-life coolants, Tracer says. This helps to avoid improper mixing and possible damage to the cooling system. Rite-Blend dye also can be used with any fluorescent leak detection lamp.
According to Tracer, Rite-Blend dye reveals even the smallest leaks in cooling systems. Just add a small amount to a system and allow it to circulate. Wherever the coolant leaks out, so does the dye, which remains at the site of each leak. When the system is scanned with a Tracerline inspection lamp, the dye glows a bright green to show the exact location of all leaks, the company says.
