waterless coolant

Postby Mxmurray » Fri Aug 14, 2015 12:47 pm

Has anyone any experience of this?
Will it work in our mx5's?
I'm thinking of getting some for my Jeep which has a diesel engine which are prone to overheating but thought it may work in the 5 as well.

I think there is still an element of "snake oil" about it. If it was really a big improvement over water based coolants, at least one manufacturer would design their cars cooling system around it. As it is, none do. There must be a reason for that.

I think the reason manufacturers dont use it could be cost.
I have read a bit about it and as there is no water there is no overheating as the coolant has a much higher boiling point than water/coolant mix.

"All manufacturers". Cost isn't a factor for the likes of Ferrari, Aston Martin, RR, Bentley, Bugatti or even the top models of Jag, BMW, Mercedes etc. The cost in those cases wouldn't be noticeable. There must be some other reason why manufacturers stick with water based coolants despite everybody knowing they have their restrictions & failings.

The same goes for the true full synthetic oils (there are very few synthetic oils that aren't actually just modified mineral oils) like Royal Purple. They make big claims but they haven't been adopted by any manufacturer so there must still be something about them that means the usual mineral based synthetic oils are best in the real world.

I have had several cars over the last few years with manufacturer specified fully synthetic oils so I don't think that that is a fair comparison.However no knowledge of waterless cooling just water wetters ie surfactants.

You misunderstand me. Full synthetic is specified for Mk2.5 and I use it in my car. Mobil 1 to be specific.
The point I was making though is that almost all full synthetic oils aren't actually synthetic, they are modified mineral oils. True synthetic oils are expensive, very rare and hard to get hold of. They make a lot of claims about protection, heat & pressure resistance and longevity but not one manufacturer uses them.

I'm all for antifreeze but you have to admit the lack of water must have some sort of advantage in reducing corrosion/rus t within the cooling system.
I think once my car is taken off the road this year I will renew the rad and pipework and fill with waterless coolant and see how it works.

How can that be true? a higher boiling point doesn't mean the engine, that is supposed to be cooled by the coolant, isn't running at too high a temperature! Car engines are designed to run within quite narrow temperature ranges, too low and they run inefficiently, too high and they run the risk of warping heads and other damage. using a fluid with a higher boiling point than water (water under pressure at that - with a boiling point considerably higher than 100 degrees C) will make no differene whatsoever to how well it moderates your engine temperature.

Presumably what they mean is that your engine is likely to lose less fluid when it does overheat.

The only advantage I can see to waterless coolant is the (possibly) reduced chance of corrosion within the system (water is not by any means the only fluid to allow corrosion!) however use of the correct mix of anti-freeze / summer coolant will mitigate against this just as effectively.

Of course the fact that Edd Chyna endorses it on the tellybox must mean it is good! :roll:

The MX5 thermostat opens at something like 88C. The engine is designed to run at around 88-95C. Any higher and the ecu will start pulling timing as high temps cause pre-ignition (which is bad).
Water based coolants work perfectly in that temperature range.

Personally I'd consider the clouds of steam when there is a cooling problem (holed hose, blocked rad, stuck thermostat etc.) to be a handy signal as none of us keep an eye on the (next to useless anyway) temperature gauge.
