Waterless coolant is a different way to approaching the cooling requirements of internal combustion engines.

In all engines hot metal in contact with coolant causes localised boiling called nucleate boiling at critical metal temperature locations in the engine. Most engine designers and test engineers are unaware that nucleate boiling is generating vapour and recondensed continuously inside the engine cooling system.

One of the problems many cooling systems suffer from is after boiling, ie the engine boils the coolant after engine shut down, due to the local hot spots and general heat soak.

Normal water and "anti freeze/coolant" mixture will normally freeze around -10 C and boil at around 115 C with a pressurised cap. Non-aqueous coolant offers a freezing temperature protection of -40 C and boiling temperature of 190 C. Along with this protection there is no corrosion to the engine or ancillaries components due to that there is no water in the system.
