Does anyone have any experience with 'Waterless Engine Coolant'? Evans has been advertising that - "No Water means No Pressure. Water-based coolants generate high vapor pressures which often cause hose failure. Evans Waterless Coolants operate at much lower pressures, reducing strain on engine components".

"Water is the root cause of corrosion in engines. Current antifreeze formulations regularly fail to prevent cavitation, oxidation and galvanic action, eating away pumps, radiators, liners etc. Corrosion build-up, inhibitor drop-out and lime-scale precipitation significantly reduces heat transfer efficiency and accelerates overheating".

Evans Waterless Coolants prevents water caused corrosion in a cooling system.

All comments all welcome.
 
I run Evans in all of my performance cars and have been very happy. Use it in both engine and after cooler.

Sometimes I need an aftercooler. You know....hot sauce.
 
Apparently, the boiling point is over 150 degrees higher on Evans over water.

Haven't tried it - but that works! I'm surprised that the general industry hasn't incorporated it . Are there any drawbacks?
 
I thought no freeze protection is a drawback ?? Not positive

That would be a BIG drawback where I live...
 
Yes, its heat carrying capacity is much lower than water.
 
"...often cause hose failure." I haven't had a hose failure since about 1966.

"...reducing strain on engine components." What strain? What engine components? The entire system is engineered to operate at 15 psi.

"Water is the root cause of corrosion..." And that is why modern coolant has lubricants, buffers and corrosion inhibitors, and why you should flush your cooling system periodically as the additives break down/get consumed and the glycol oxidizes.

Isn't this Evans stuff just 100% propylene glycol with an inhibitor package? 1 gal food grade propylene glycol = $15 + $1 additives, sell for $44.

If you have overheating problems when tracking, it seems to me 100% water is better than 100% glycol.

Sea level 14.7 psi + 15 psi cap = 29.7 psi total system pressure. Pure water boiling point = 250. 50/50 water/coolant = 265.

What difference does it make if the boiling point is 400? Are you going to run your engine past 240? Nice to know that the coolant won't boil even as your engine seizes.
 
I always thought the boiling point of water was 212

At sea level. The boiling point increases with pressure. Conversely, it decreases with altitude as atmospheric pressure decreases.

Ask me about feral hogs.
 
I've seen Xcentric. He IS a naked mole rat.

I want one of those the next time you catch one. They make good sausage.

I disposed of the four that I shot. Stubb and Lee Roy keep the ones they trap, plus $40 per pig. One more left (we hope).
 
Guess I'll stay with Ford recommendations in the Owner's Manual -

Right. I see now that you were giving the boiling points at that pressure. I am familiar with the laws of physics. Just read your post in a hurry.
