This unique wetting agent for cooling systems can reduce the coolant temperatures as much as 300f. This liquid can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum as well as cast iron, brass and bronze systems.
