Waterless Coolant

Consider me interested. A pressure-less coolant system would be great, as long as the higher coolant temperatures don't shorten hose life. You'll need more than a couple of weeks to check that out.

Sorry, I still don't understand why a pressureless system is of any benefit at all. Cars are designed to operate at around 15psi and have no trouble doing so throughout their service life.
I'm not even sure how a modified system would ensure that airborne moisture never comes in contact with the coolant. Even minor contamination reduces the effectiveness of the fluid to worthlessness.

I have some temperature strips placed to keep an eye on this. I personlay don't think the temperature will be so much hotter that failure would be because of that, but time will tell. Some hoses on my car are 120Kmiles old, and the rest 250Kmiles.

For now my guess is that the little moist that could come in, will be just as well expelled as vapor again. But I am no expert on this area, and will measure it over time to be sure.

We are (nearly) all driving old Jags so, yes, a pressure-less coolant system is of interest. Best of all, Avos is doing the research.

I always enjoy reading about the latest magic fluid developed for cars. Like my dear departed grandmother always would say, "yeaaaah boy!". She was being sarcastic with all of the outlandish claims.
I used to read a certain performance catalog published in Ohio. One time I read about a product that kept your exhaust pipes cooler and on another page, another that kept your exhaust pipes hotter, both designed to improve performance. That's when I laughed, threw the thing in the trash and never looked at it again.
There will always be products. Consider wetter water. If it is so good at absorbing heat, how does it lose the heat in the radiator? It can't be both.
If you use the proper coolant and keep it changed when it is supposed to be changed, you'll be fine. Hoses are not going to last forever anyway. Pressurizing the system increases the boiling point rather than have coolant boil away and not stay in a liquid form in your engine.
I do not know of a single auto manufacturer who uses wetter water or any other magic fluid in their vehicles.
What next? Marvel Mystery Oil?

Am not so much in favor of water wetter, as far as I understand its main strength is that it reduces the surface tension, so there is less loss of heat transfer to the water (not water wetter) when boiling occurs in hot spots, that is good. The OEM coolants also have some inhibitors that have this property added, so in a way almost all auto manufacturers have adopted it;-), so for a standard OEM setup it is not needed at all.
Anyway, I try to inform all as best as I can about the actual performance and aspects of this Evans coolant. As said it has pro’s and con’s, and I need ensure for myself if the con’s are acceptable or not for my setup.
But tell me more about this Marvell Mysory Oil, what sort of magic stuff is that ;-)

Modern coolants already have all the ingredients of 'water wetter' blended in. Adding more is of no benefit. The purpose of the surfactant is to aid in heat transfer. Stating that it simply absorbs heat is misinformed.
I'm surprised to hear about so many burst coolant hoses. Where is the research indicating that the hoses let go because of pressure and not heat? If it's heat, the Evans coolant will be a step in the wrong direction due to it's inferior heat transfer capacity.

Anyway, I have not seen any increase in temperature (in the short driving I’ve done so far), which is also not what I would expect, maybe under certain conditions where the radiator and fan aren’t able to transfer enough heat away. That will be for spring /next summer to test under some heavier engine loads.

I underestimate nothing. I have trouble accepting that there is actually a real world problem that needs to be fixed by means other than replacing old worn out hoses.

I don't recall any hose or pipe bursting unless there was pressure inside. In my mind, the only real downside to Evans might be a higher IAT. Anyway, we are in luck, because...
--> Avos will do coolant research on Evans, and
--> Tony1963 could do coolant research on sea water, and
--> the rest of us can sit back and wait for results.
