RE: Hemmings Classic Car Collector-car-magazine, August 2013, #107, page 70-72, "One the Verge" Coolant phase change in an engine: By Ray T. Bohacz...
I'm quoting the second to the last paragraph: "For many years, it was believed that water was the best engine coolant, since it has a specific heat rating of one --but it really a poor choice. Even if you do not consider the corrosion it causes, the low boiling point, even when used with a radiator cap, and the high surface tension mean that it will not do an effective job of removing heat from the cylinder head when compared to an application-specific engine coolant- no matter what the dashboard gauge states. Those who subscribe to the water logic for engine cooling are usually the ones on the side of the road with their hoods up when the going gets tough".

This a very in depth article on cooling, different additives, charts, etc. I hope my citing sources is enough to allow me to pass on this information to the forum.
Hope this helps.
