Viper Eyes UV Leak Detection Dye, Part No. 483926, is specifically designed for use with extended life coolants. The new dye is compatible with all engine coolants and features a new formulation that won’t discolor engine coolants, which can lead to misdiagnosis of engine problems. The new dye is GM-approved for use in detecting leaks in systems that utilize their long life coolant.

Traditional UV Leak Detection Dyes have presented difficulties when used on systems that utilize long life coolants. Dyes typically have had a green tint, which can later lead a technician to believe a vehicle’s coolant has been compromised thinking it contains traces of domestic green antifreeze. This leads to unnecessary service and misdiagnosed engine problems. The new Viper Eyes Coolant Dye will eliminate this potential problem. It is compatible with all UV leak detection lamps and fluoresces blue or green, based on the lamp used.

The new dye is available in a kit, Part No. 483926, that includes (6) 1 oz. bottles. The kit includes (6) installer labels that can be added to vehicle, showing the service performed and the service date. A 1 oz. UV Leak Dye application treats up to 20 quarts of engine coolant.
