Traditional cooling system treatments were designed for vehicles in the 1930s and 1940s. The make up is harmful to today’s hi-tech aluminum engines. Nitrate and silicate harm the cooling system and the environment. Cool Flo’s primary inhibitor is formulated around molybdate. Cool flo prevents scale, scum and corrosion build up that can clog the cooling system and eat away at the solder and other parts of the cooling system. A clean cooling system will prevent overheating of the engine and transmission, since it is dependent on the radiator. Cool Flo has been given a government specification number signifying that Cool Flo has been tested effectively in all types of vehicles. Special surfactant in Cool Flo prevents cavitation by eliminating air bubbles in cooling systems of diesel engines.
