evans waterless coolant - anyone using?
Discussion
I've ran it for a year in my 3000m and that only comes out for spirited drives on hot days with no problems, it runs roughly 5 degree cooler on motorway with constant cold air flow and rose slower when caught in traffic, it has been pointed out to me before though that I had the engine reconditioned and all cooling parts renewed, so this would not be an accurate result. I believe someone on here ran it in a 3000s for the liege Brescia liege rallye and encountered no problems.
I've been running this in my daily driver/track day car and on our pair of endurance RX8's with no problem and noticed nothing strange but the heater feels a tad cooler on demist, that's all.
I know some people dislike change but I always try the new stuff on myself first and I have found some dodgy stuff along the way but in this case it seems all good

a clear sign that the evans isnt picking the heat up from the engine nor releasing it as effectively to the heater matrix radiator surely!I thought the idea was that when you get to overheating conditions .... and the water starts to boil / expand (and dumps contents out of the cap) that the evans will remain stable still protecting your engine at this time?

Yep and that's why the Mosler 24 hour and GT cars have all run Evans for the last 10 years as do the Honda factory motorcycle race team.I thought the idea was that when you get to overheating conditions .... and the water starts to boil / expand (and dumps contents out of the cap) that the evans will remain stable still protecting your engine at this time?

Well the motorcoss team has evans as a sponsor so in effect they are buying their kudos. Indeed the evans response to the no-rosion article dismissing the evans claims shows only the honda motorcross logo on it's paperwork. I would have thought they would have used every major company they could to create an air of authority in that reply.Also their news pages are very sparse and show no major manufacturer or race team tie-ins really.
On the Mosler thing, I can't find any mention of mosler running evans coolant apart from on the evans site itself where it mentions mosler automotive racing who actually don't seem to have a web presence at all from my brief googling. certainly I cant find any mention on mosler's own site, even in their engine tech section, and you would have thought they would have mentioned it there.
But anyway.. I'll stick to water/antifreeze on the basis that it's what we've used successfully for yonks, it's cheap and easily available, and more importantly is what your liquid-cooled engine was designed for.
It's easter weekend, the sun is shining and better things beckon.
aam oot.

That's great for a racing team with loads of mechanics and the engine constantly being rebuilt etc and lorry loads of equipment with barrel loads of waterless coolant that they no doubt get for free but for joe public is it worth all the hassle speacally if you do spring a leak and lose loads of the stuff by the road and have to top up with water than throw away the waterless coolant then flush it out then fill up with expensive stuff again, I am not being rude but I nearly changed to waterless coolant but my mate pointed out all the cons
If steam pockets worry you then the "water wetter" products are supposed to prevent this. I ran some of the Millers "extra cool" with blue antifreeze for a couple of years- and it did seem to make the temperature more stable, but I was not happy with the rate of corrosion during that time. These products claim to prevent corrosion,(with or without antifreeze) but I was not convinced. Ive switched to red antifreeze now, and the cooling system shows no signs of sediment, but Ive not tried it since. You will find loads of water wetter products on Ebay for about £15 if you to try one without breaking the bank.
The last thing I worry about is money as I have 3 TVR,s and just had a TVR Power 4.5 put in my T350, its just all the hassle if you get a leak and don,t carry gallons of stuff specially on a trip abroad and space is a premium in a TVR and my wife does not travel light and my mate said to use wetter water or similar

Those are sealed engines, 6 for a season, run over pressurised cooling systems compared to road bikes or cars and are good for 18000+ rpm, producing 260bhp per ltr.
I can the resemblance to the Rover V8 clearly between the 2

As in MotoGP? Really... Are you sure?

That's him that's the culprit

If money is not an issue, not sure why Evans is a hassle, if you TVR is well maintained chances are you won't break down, but if you did and you did not keep a top up with you as they supply a small 2 ltr can, then you can add water to Evans and continue on your way, though most countries in Europe have distributors and not that hard to find. No need to drain to put water in just add. Temp fix until you have it repaired and Evans put back in.It's a bit like saying I want solid rubber tyres so I can't get a puncture and that puncture might ruin a new tyre.
Every breakdown is hassle, but with good maintenance breakdowns should be a rarity.

Mosler don't get for free, and reuse the Evans in between buildsI am not being rude but I nearly changed to waterless coolant but my mate pointed out all the cons

I have seen lab tests on Evans and corrosion tests, and although you can't illuminate all corrosion it's still better.Also their news pages are very sparse and show no major manufacturer or race team tie-ins really.

When Mosler first started using Evans, before this newer formulation, why would they mention every product, especially give the competition the heads up. They are there to promote their cars not the product used within.
Jaguar Heritage Centre also use Evans, not sure they would mention it on the site, without a financial gain.

Evans has 5 coolants, all are from the same base, the difference is in the additive pack, cast iron blocks are suited to classic Ali to power cool.
Water is without doubt the best heat transfer fluid out there, but on its own is very corrosive, and like everything it's about compromise. So anti freeze gets added to inhibit the corrosion and add freeze protection.
What Evans offers is an alternative to this old technology.. Most if not all the major engine manufacturers inc car, have Evans testing or tested somewhere, there are several non disclosure contracts with Evans with a lot of money in testing and R&D.
Evans was so good that 12 plus years ago one of the worlds largest car manufactures tried to copy Evans which ended in court.
We have used Evans in many varied engines and not yet found a downside.
