The rating is higher because instead of having thermostats in the 160-180 range like the old days, the engines are built to run around 200 degf. The E-Type has what, a 4psi cap rating? Modern cars have a 20psi rated cap. The main reason I would like to see it, and the reason I am switching my modern cars to waterless, is because plastic piping and hotter running engines don’t mix. True, but I think it’s very unfortunate that new cars aren’t coming with waterless coolant, and I really wish it was at least an extra cost option when buying a new car if the automakers don’t want to increase their cost. This product will allow your engine to run hotter without boil over but is that what you really want ?Īs far as I am aware no mainstream car manufacturer currently see’s the need for waterless coolant. “Waterless coolant provides SUFFICIENT heat transfer” so, should one use it because it has a higher boil temperature and allow the engine to overheat without boil over ? 'Water has superior heat transfer capabilities ' so, even if its close to the operating temperature of the engine ,as long as the engine is in good operating condition all should be good. Waterless coolants provide sufficient heat transfer, boil at a higher temperature, and are non-corrosive.Water has superior heat transfer capabilities but water’s low boiling point is close to the operating temperature of an engine, and water can cause corrosion.If your engine did not have an overheating problem and all of a sudden (or gradually) has one shouldn’t one find the problem rather than masking it ?

My concern with this remedy is that it is masking an issue and not solving it. In a conversation about overheating issues and potential remedies one individual said : “after I started experiencing overheating issues I just switched to Evans waterless coolant and problem solved !”.
