evans waterless coolant - anyone using?
Discussion
Seen this on Wheeler Dealers and as I need to replace my coolant I did some searching. Its seem a bit of a no brainer to use this stuff and appreciate its more costly but the benefits seem to outweigh the price differential. Only question is do I need the Classic Cool or Power Cool?
Don't recall seeing any posts relating to its use or hearing anyone using it.

Only issue seems to be flammability but it is flammable over 500 degrees C and I'd be concerned if the engine/exhaust are getting anywhere near that level. Surely all the electrics will have melted by then?
If glycol is flammable at the same temp then I think its a safe risk.
Why suggestion are made about running the engine hotter - it runs at what it runs at. You just need to keep an eye on the gauge and compare against "normal" operating temps.
I'll check with my insurer though first.

Nice Derek. You should have saved that offer for the Growl but its now out there.
I've been told by Evans to go for the Power Cool. I'll need 10 litres plus 5 of the prep fluid. Its £94 delivered for 5 litres of each plus £63 for the Power Cool alone on a certain auction site. How do you compare?
The positives for me are significantly more than outweighing any combustion issue. The water usually floods out the rad which is far enough away from the exhasut to be a concern. As there is no pressure the hoses shouldn't blow and maybe the rad lasts longer as ther is no pressure and no corrosion.

've looked at this but not gone with it (yet) but can't figure out why you only need 5ltrs of prep fluid?
Rich,I read somewhere you dont need the same amount of prep fluid but couldn't find the evidence, other than this for now:

Its just holding the remaining water and crap left after draining.

States 1 gallon of fluid needed for petrol engines. 1 gallon = 4.5 litres so 5 should be enough.

I dont have any problems with cooling, but as a precat the opening at the front means the fans come on a fair bit. Just need to change the fluid anyway and saw the TR6 on Wheeler Delaers and it seems like a good idea.
I have an ally rad so it may last a bit longer with this and they are not cheap to replace.

it is corrosive for some metal / rubber more so than water ?
Which metal. Seems to be non corrosive for metals in our engines. Rubbe r- no idea.
it makes your engine run at a lot higher temperature's and that cannot be good ?
From Evans waterless coolants website:
Q. Will Evans Waterless Coolant cause my engine to run at a higher temperature?
A. No. The operating temperature of the coolant may increase slightly, however the temperature inside the engine will be more consistent
if you get a leak, just say in France you will need to carry 5 litres or drain the system and put water in, then start all over again when you get home ?
From Evans waterless coolants website:
Q. Can I add water to Evans Waterless Coolant?
A. Yes, but only in an emergency. Evans Waterless Coolant is completely miscible with Water, however once you exceed 5% the benefits of Evans Waterless Coolant are compromised. We recommend that as soon as possible you refill with Evans Waterless Coolant to regain its benefits.

1.The boiling point of water is only 100°C.
2.Because an engine operates very close to the boiling point of water,(within the engine block and cylinder head boiling actually occurs), thus causing pressure within the cooling system.
3.The boiling point of water is the failure temperature of the cooling system.
4.Water vapour (steam) has almost no thermal conductivity.
5.Water is aggressive toward cooling system metals and promotes electrolysis between dissimilar metals within the cooling system.
6.Water contains Oxygen which encourages corrosion in any cooling system.

maybe we should ask Ferrari, Ford, Toyota etc why they don't use waterless stuff
I'm sure there are lots of things the manufacturers could do but they al add to the initial retail price which they want to keep that as low as possible - if all items were another £50 then the cars would be £2-3k more. You dont even get a spare wheel anymore or my last few cars not even a cigarrete lighter as its now an optional extra.I'm still not 100% but still on the positive outweighing the negatives side at the minute.
