"Waterless coolant" has been around since the late 1930s. It was originally just ethylene glycol. The military aircraft industry used it as a coolant in Allison V-1710 liquid-cooled engines in planes such as the Curtis P-40, among others. Although it had a high boiling point, it created other problems. One was that it leaked through microscopic openings in hoses, gaskets, etc. The most serious problem was that its specific heat ( the amount of heat absorbed that causes its temperature to rise one degree C) is far less that plain water. A compromise was finally arrived at which worked well- 50% water & 50% ethylene glycol. It had an acceptable specific heat, boiling & freezing point, and was (with additives) non-corrosive.
Evans offers a variety of waterless coolants; their "heavy duty" coolant is a mixture of ethylene glycol and propylene glycol. One thing to bear in mind is that it will not absorb as much heat as plain water. It's specific heat is 2633 J/(K kg) while plain old water is 4182 J/(K kg). That is a big difference. Evan's specialty racing coolant is 100% propylene glycol. Note that their handling instructions warn that it readily absorbs water from the air so the container should always be kept closed. In other words, your cooling system may be "waterless" after it is freshly filled but it will eventually contain a percentage of water.
For racing, you can't beat water as a coolant but you should drain it afterwards to prevent rust & corrosion.
