The car has been tuned - rebuilt carb, points/condenser/distributor cap/rotor, and timed. I agree that liquid water is the best heat transfer medium but it also causes corrosion, scaling and electrolysis of the metal surfaces and degradation of the cooling system. I have seen cracked cylinder heads, blocks where the buildup of deposits in passages created hot spots that resulted in delta temps that resulted in cracks. I understand that if you have additives in your cooling system and routinely flush your system to remove corrosion deposits, etc. you can minimize corrosion damage. Additives breakdown and systems are not always flushed - one does not know the care and attention that was given to old engines 60-70 years old. I am willing to run with a higher operating temp in my cooling system with Evans knowing that I am minimizing further corrosion and buildup of deposits. I have had success with Evans waterless coolants in my 58 vette, 78 vette, 63 RR Silver cloud, 60 cad and 63 cad.
