Well, not so fast. Running an engine "hotter" is not necessarily a bad
thing. There's nothing magical about the red zone on the temp gauge - it
just tells you when you're nearing the place where water boils, rendering it
useless as a coolant. Evans may be correct about localized
boiling/condensing cycles in normal use at "legal" temperatures making for
localized hot spots. In theory, preventing that localized boiling MAY work
to reduce detonation etc. It seems to be a tradeoff with reduced heat
transfer for the no-water coolant. It all depends on what you want - a safer
motor or a cooler motor. Water transfers heat better and is a more efficient
coolant UNTIL IT BOILS. The Evans coolant theoretically gives you more
protection at the boundary conditions, after water has ceased to work. In
any case, there are places in your engine that are a lot hotter than the
boiling point of water.
