Applying modern technology to engine coolant
The Australian automotive industry is steep in tradition. Though rooted in convention, the High Performance community is more apt to apply modern technology than most if not all other businesses. —– There is a caveat though, it has to have an intrinsic value. Technology for the sake of change does not cut it. Many modern advances have made their way into the modern engine, yet the most sophisticated of engines, are still cooled with a water-based anti-freeze. A technology that has roots from 100 years ago, a glaring paradox.
No one can deny that traditional water- based ethylene-glycol (EG) anti-freeze works — there are not cars and trucks overheated in everywhere. Pushing the envelope is a necessary component for every aspect of a high performance engine, while keeping maintenance and repair costs in check.
If every other technology within a high performance engine has advanced, one cannot help but wonder if there is a better coolant to use in an engine? A product that increases the service life of all of the cooling system components, eliminates top- off, eradicates cylinder liner cavitation along with electrolysis and improves power and fuel economy by lowering the combustion chamber temperature of the cylinder head. There is!
Evans High Performance Coolant is a waterless formulation of glycols that never freezes, does not boil until 190 degrees C and does everything and more mentioned in the previous sentence. To accomplish this Evans Cooling Systems has designed a product that does not employ any water at all and thus, eliminates all of the issues that traditional coolant of any color inherently brings to the engine.
To understand the basic theory of the Evans waterless coolants there is a need to look at how heat transfer in an engine occurs.
When studied, it quickly is realised that the job of the liquid is to cool the engine and the task of the radiator is to cool the liquid. This is often looked at the wrong way — the radiator does not cool the engine. It drops the temperature of the coolant so that it can go back into the engine and pull heat out of most important the cylinder head and then the block.
When an engine overheats and spits out coolant it means that the liquid cannot absorb any more of heat and the radiator cannot drop the temperature sufficiently to let the liquid do its job. Once this basic tenet is understood the entire process along with the deficiency of traditional water-based coolant becomes apparent.
The Evans technology enjoys the ability to absorb almost 60 degrees C more heat from the engine than 50/50 EG and water. In addition, the Evans products are more slippery inside the engine. This is read in chemistry as surface tension and the metric used is dynes/centimeter. By releasing in the cylinder head easier, the Evans Coolant reduces system operating pressure which puts substantially less strain on hoses, seals, gaskets, the radiator and heater core. In addition, the vapor pressure is much lower, further reducing system strain.
By eliminating water, system corrosion, degradation, liner cavitation and electrolysis is no longer a concern.
