Use With Long-Wave UV Lamp; Ford Approved; Glows Blue; 16 Oz. Bottle; Dye-Lite(R) Clear-Blue(TM) Extended Life Coolant Dye is leak detection dye for all engine coolants, including extended-life. It has been Ford Approved. When the dye is added the coolant fluoresces bright blue and requires a long wave UV lamp such as the Tracerline(R) TP-1390, TP-1600P, TP-1700P, TP-8690-UV, or TP-35000 Maxima series. Does not distort coolant color, which could lead to misdiagnosis of engine problems. Safe to remain in the system until the coolant is changed.
Tracer Products' parent company, Spectronics Corporation, invented fluorescent leak detection in 1955 and is the world leader in ultraviolet and UV/blue light technology.
Tracerline(R) leak detection is so effective that one of the "Big 3" U.S. auto manufacturers has installed Fluoro-Lite(R) dye in the air-conditioning systems of all its cars right from the factory since the 1995 model year. Fluoro-Lite is also factory installed in new cars and trucks by other automakers in the U.S. as well as Japan, Europe and Korea. Tracer Products' Fluoro-Lite/P(R) and Fluoro-Lite/E(R) dyes meet or exceed SAE standard J2297 for refrigerant leak detection in R-134a/PAG A/C systems.
