Unique agent for cooling systems that doubles the wetting ability of water. Reduces or eliminates bubbles or vapor barrier that form on hot metal surfaces to reduce coolant temperatures by up to 20°. Rust and corrosion protection allows for use of straight water in racing or reduced antifreeze levels in warm climates. Improves heat transfer and reduces cylinder head temperature. 1 x 355ml bottle treats approx 15 litres of coolant
