Coolant
Does anyone have any experience with "Evans Cooling". They claim that it is a waterless coolant, wetter than water, however will not leak by gaskets and seals. Boils at 375*F. Freezes at -75*F.
Hotspots within the engine cooling system cause localized boiling. The steam generated significantly increases the pressure within the system putting stress on hoses and other components. Evans Waterless Coolants have a boiling point of above 375°F and will not vaporize within the cooling system. Cooling system pressure is greatly reduced as Www.evanscooling.com Thank you for any input.

Re: Coolant
I have never used it but I have heard from more that one source that their engine ran 10-20°F hotter. That may be a good thing, my engine seems to run too cold, 160-165° with 50/50 antifreeze.
You may want to research it further tho |

Re: Coolant
No Water - No Erosion
As water flows through an engine cooling system it is subjected to many obstacles and constrictions. The resulting turbulence creates rapid changes in pressure forcing small pockets of water to vaporize. This process produces voids in the liquid known as "cavitation bubbles". As the pressure normalizes the bubbles collapse generating forces great enough to punch holes in the surrounding metal. Evans Waterless Coolants have a much higher vapor pressure than water which means it is far less likely to vaporize when subjected to the turbulent pressure changes. Tests performed by Southwest Research Institute conducted on behalf of John Deere concluded that Evans Waterless Coolants achieved results that can not be matched by any water based antifreeze. The 250 hour engine dynamometer test, approved by ASTM international, quantified the amount of cylinder liner pitting caused by cavitation errosion. Many coolants were tested during the trial period and results confirmed that up to 70% less pitting occured when using waterless engine coolants.

Re: Coolant
A friend has a 41 lincoln V-12, that was overflowing when shut down, in hot weather. With Evans, it does not. It seams to run the same temperature, or even a little cooler.
The operating temperature of an engine is very close to the boiling point of water. Hotspots within the cooling system can lead to localized boiling, generating steam which increases system pressure and prevents effective cooling. Evans Waterless Coolants have a boiling point of over 375°F, far above the operating temperature of the engine. The high boiling point ensures that the coolant remains liquid at all times enabling consistently effective cooling. Eliminating water elimates the problem of boil-over and after-boil.
