I considered using this in my 1293 S/C Eaton Suck Through set up. I installed a rad mounted kenlowe fan to keep things cooler in standstill traffic. The car runs perfect and timing etc is spot on. All new parts, larger impller water pump, 2 core rad. I just feel it naturally runs hotter than when I did not have a super charger. I have a mechanical guage which hopefully is accurate, and takes the feed from the usual cylinder head location. Would be great to run things a little cooler, if there is any long term benefit from this?

So it has a slightly lower specific heat capacity than water leading to slightly higher running temperatures. Setting aside corrosion, I do see the advantage of a higher boiling point, so I wouldn't call it snake oil. You could be looking at 20 years worth of anti freeze for the same price though - assuming you don't lose any (In a Mini!)


Cooperman, their argument seems to be less localised boiling in the head. I'm not convinced though, turning water into steam absorbs heat without raising the temperature (latent heat capacity) and, being less dense, the steam will bubble away from the surface. Either way, unless there's a complete failure in coolant circulation, a lower coolant temperature = more effective cooling. I'd imagine a 180 degree boiling point still wouldn't eliminate local boiling, considering petrol burns at at 2-3 times that, without considering the pressure.

Using the same basis maybe 100% Glycol would work.
Anyway, I won't be using it as a 30% glycol mix has always worked fine.
The theory seems to be that you use this stuff on cars which run hot so they still run hot but don't boil the coolant fluid off so the running hot is not a problem. Running too hot is a problem whether the coolant fluid boils or doesn't boil. The engine should always run within its optimum temperature range.

VW have been cooling engines with out water since the 1930's

You do have to wonder about products that use, or invent, their own terminology to explain themselves.

I had the same thought. Then I started having flashbacks to the Monty Python skit for "Crelm Toothpaste".

If the engine is running at 180 degrees, everything will expand and there is a high likelihood of seizure surely?

Thanks for everyone's posts, they all make interesting reading!

The top and bottom of it is their website OS there to sell their products!

Ahauhuahua BEST reply ever!!

I cant imagine how many headgaskets you'll go through running with coolant at 180°

I spent an age researching coolants for our electric racing cars at work. You come down to two options, water has an unbeatable SHC (specific heat capacity) so adding other things won't improve cooling but may prolong life of components or prevent freezing, hence the use of antifreeze. The only other viable option is a total loss evaporative system using something like alcohol, if you fancy gallons of highly flammable fluid being boiled and vented........ Pretty obvious which we chose until they banned liquid cooling.

It would appear this product is being used in Rotax aircraft engines in the ultralight sport category planes class as this question has been asked in an aviation forum i use.

Not sure about this product but that wifi spray is supposed to be really good...

I have been away for a few days, so have just seen this. I can tell you that prevention of DNB is a very good thing, as water does indeed shift heat far better than steam. They really do not like DNB in nuclear reactors, for instance. Admittedly they run rather hotter, and therefore at a higher pressure, but the principle of shifting heat from the source to where it is dissipated is not very different.

But I am most interested in the elimination of corrosion. That has to be worth the money. Rusty sludge in the block and head is the root cause of many overheating problems, and core plug corrosion is a nuisance too.

Just don't put it in an engine with a dodgy bypass hose or you will lose your investment!

I prefer my coolant wetter... Ill just use Water Wetter.... actualy proven in many vehicles

[holmesy]

this stuff is mainly for race cars, it main purpose was for the grid line ups. on the grid the cars radically build up heat and boil over, by increasing the boiling point to 180 its reduces the chance of this happening without a pressure unlike your pressure cap on your radiator which increases the boiling temp by holding the pressure up. we found the evans stuff expensive as we would need over 2 bottles of the stuff plus the engine flush for our race car, so after talking to our engine builder he put us onto an even better product than evans, JOHN DEERE Tractor Coolant. it is actually better at cooling than the evan and has an even higher boiling point. we paid 60+vat for 25 litres, excluding the engine flush.

the jd stuff is made for those combine harvesters that are running flat out for more than 24 hours straight. it has made a difference on our race car, the temperature builds up to its running temp but doesn't go over the top. i will be trying this in my recent mg metro engine swap to see how it is for a road car but the jd stuff is twice the quality of evans for quarter the price.

by the way water still dissipates heat faster than any other product you can by on the market
