Yorkshire Classic Cars is now a stockist of Evans waterless coolants. The fluid is a patented synthetic formulation which contains no water whatsoever. This eliminates any corrosion aspects caused by the inclusion of water in a cooling system, such as pitting caused by small steam bubbles present in hot spots in the combustion chamber.
The system runs at virtually zero pressure because of the lack of steam generation, as opposed to that which occurs when using other standard 50/50 coolants. Therefore this system is significantly more relaxed on the hoses, gaskets, seals and the entire system. This fluid will not boil, in turn eliminating any overheating issues allowing the engine to run comfortably at a slightly higher temperature. This also increases engine efficiency and performance. Because there is no water present, there is never any steam generated and so the coolant will never need topping up. There is no water or vaporisation occurring to interfere with the inhibitors in the fluid and this means that the coolant will literally last the lifetime of an engine and will never need changing. The coolant is also completely non-toxic and is therefore more environmentally friendly and safer and easier to dispose of.
