Doubles the wetting ability of water. Improves heat transfer. Reduces cylinder head temperature. Reduces rust, corrosion and electrolysis. Cleans and lubricates water pump seals and can be used with all antifreeze/coolants. Improves the ability of coolant to wet heat transfer surfaces by 50%. This provides significantly better coolant contact in the cylinder head and can reduce coolant and head temperature. Can be used with 100% water in racing but does not protect magnesium or alter freezing point.
