EVANS WATERLESS COOLANT
By Mike Tourville
What if there was a coolant for your Rolls Royce or Bentley that: (1) will never boil or freeze,(2) will not form vapor or build excessive pressure, (3) exhibits no electrolysis or corrosion of iron or aluminum, and (4) has no additives that ever need replacing, thus lasts a lifetime?The common culprit in each of the above issues is water, and Evans waterless coolant can put an end to the ongoing battle against corrosion, boil-over, and the headaches of periodic coolant change outs.
Boil-over Protection
Evans High Performance Automotive Coolant has a boiling point of 375° F, more than 150°F above normal operating temperatures.When coolant turns to vapor it loses 96% of its effectiveness in transferring heat from the cylinder heads, which of course is where most of the engine heat originates in the first place. Evans has the ability to absorb a high amount of heat before boiling resulting in the lowest metal temperature in the cylinder ahead. On the low end of the temperature scale, Evans protects to -40°F. At those low temps, Evans will contract, unlike water which expands and can potentially cause freeze burst damage.
Pressure Decrease
Evans remains in its liquid state, meaning it won’t form vapor, build pressure, or boil out. With no vapor pressure created, EHPC also allows fresh coolant to contact every internal engine water jacket crevice. Evans maintains constant liquid-to-metal contact, avoiding hot spots, and assuring efficient and consistent heat transfer. Tests have demonstrated that a typical 50/50 water/glycol conventional coolant will build a pressure of 16 psi at 230F in a hot engine. The same system with 100% Evans would only hold a pressure of 2-4 psi. Older engines often have parts that are weakened by age. The 10-16 psi of constant cooling system pressure puts a stress on those parts and at some point they will begin to fail. The result is a messy cooling system leak. With significantly lower pressure, hoses, seals, gaskets last longer. Evans cannot prevent leaks, but the lower pressure makes them less likely to occur, with less coolant volume loss. In the event of a coolant leak, Evans will be a slow drip, rather than a high pressure, high volume expulsion of hot water/glycol coolant.
