![]() I have always used a can or two of water pump lube and corrosion inhibitor in my street and race cars. The significantly higher boiling point of Evans. Larger radiator is a good idea, because when functioning properly, more heat does come out of the cooling system. When water turns to steam it pressurises the cooling system putting strain on hoses and other components. ![]() Many products sold today as 'antifreeze' are actually a 50/50 mix, I expect this is what most people have that they call 'pure antifreeze'. It also has a higher boiling point than straight water. It is more viscous than a coolant mix and will require a new design of water pump in many cases. The eutectic ( lowest freezing point) is about - 65 F with 50 water. If you use a high pressure cap in the 20# range the boiling point of the coolant is raised quite a bit and proper hoses and gaskets should work fine and not leak. The issue with Evans is that it will take on moisture from the atmosphere, eliminating the amazing boiling point. SCCA and as far as I know, NASA allow antifreeze but most circle track organizations don't allow it because it is so slick when it gets on the track. Thats a lot less than the temperature of the engine headers.Īlso If you ever get an engine leak and pure glycol gets under your tires, you will think your tires have been replaced by ball bearings. Evans Waterless Coolant also provides protection against further corrosion, erosion and other problems caused by. The high boiling point ensures that the coolant remains liquid at all times enabling consistently effective cooling. I did look up the MSDS for PG and sure enough it will self ignite at about 699 degrees F. Evans Waterless Coolants have a boiling point of over 375Â☏, far above the operating temperature of the engine. You can get both EG and PG and mix it yourself. Evans coolants do not use water, and therefore eliminate the engine problems caused by water. Their MSDS (Material Safety Data Sheet) states that it is 70% Ethylene Glycol and 30% Propylene Glycol with "Proprietary" corrosion inhibitors which are present in standard antifreeze brands available for about 15 bucks a gallon at your local auto parts store. Evans manufactures the ONLY line of waterless engine coolants.
