The combination of heat, oxygen and minerals in water causes the formation of oxides on metallic surfaces in which they travel through such as the radiator and other parts of the engine that the coolant cools, causing premature rusting and breakdown of essential cooling equipment on your vehicle.Įnter the Evans Waterless Coolant, a specially formulated coolant that does away with the need for water.
The other issue with water is that it often causes corrosion within cooling systems. These are caused by the vapours of the mixed solution of water and coolant, which cools and solidifies on the ends of these fittings. Not only does it spell overheating prominently, the mixture of tap water and coolant creates another problem of crust-caking on radiator pipings. This is risky in automotive engines that are force-induced or are of high compression in nature, especially in our country’s sweltering weather. As it turns into hot vapour, it increases pressure and strain on the cooling system. However, when it boils into its vapourous state, it does not hold any merit, since its gaseous state means that it has lost its capacity to reduce and effectively dissipate heat that is being generated by an automobile’s engine. I have not used Evens yet but it promises to be an Anti-Freeze that really provides Zero cooling system rust.In its liquid state, water is an effective cooling solution for machinery. There is normal fluid expansion due to the slight hydrostatic expansion when heated.Įvans will not boil when allowed to be exposed to atmosphere pressure when the engine is at running temperature. Less pressure means less stress on all parts of the cooling system, and less chance of leaks. The other advantage is that when the engine is at normal running temperature this fluid will not boil at atmospheric pressure and does not require the cooling system to be anywhere near the pressure normally used. This is in contrast to the normal steadily decreasing cooling capacity caused by internal rust with anti-freeze + water. Therefore the cooling system should retain 100 percent cooling capacity for many years. Because there is no electrical conduction, there is no rust inside the cooling system.
When metal enters Evens fluid it still can not conduct electricity. The advantage of Evans is that it is used 100 percent with no water. Once contaminated with metal water becomes conductive and supports rust inside the cooling system. If you do change it out and or flush system and change it, how often?įrom what I understand, distilled water quickly becomes contaminated with small amounts of metal once it is put into any engine. How long do you leave it in for? Do you flush you cooling systems after many years of using it, or just leave it in, or change it out? I understand that because of the Zero electrolyte action (Zero rust) that Evans has a very long use life. I would rather spend an extra hundred or more to get a radiator and heater core that is good for a decade. It seams all radiators that are made over-seas are good for about 18 months and then they get several very small leaks. and heater core (use to be Modine, now Proliance). I figure the 2001 Impala is due for replacement of original radiator and heater core next spring, and am thinking of switching it to Evans + type then. I like the idea of an antifreeze that has Zero rust, and low pressure. Stock engines, well maintained cooling systems, no over-heating problems with any cars. For now, thinking of putting it in to an 2001 Impala with a 3.8 and it's second intake gasket, and possibly a 1985 Olds Delta 88 5 Liter Gas engine 2 door, and possibly a Buick 1996 Roadmaster.
