Personally I wouldn't - with the Heath Robinson TVR cooling system you will probably be constantly losing & topping up coolant - and I understand you are not supposed to mix it with conventional coolant - so what do you do if you breakdown with a blown hose or something? In my view its fixing a problem that doesn't exist. Just because its more expensive doesn't mean its better.
Hi All
For me its a no no, you could use computer cooling fluid its cheaper, I use Zalman in mine and I pay about £ 6 a litre, don't think I'l use it in the car.

Have to agree with Chris on this as well though - I'm not sure what the advantage is, if your cooling system is otherwise working correctly. And if it isn't, it would be better to fix that first, surely?It's slippery, it doesn't evaporate and it can catch fire.
Em, no. I'll stick, thanks.
I hear your points. I guess I'm thinking that if I'm gong to do it, it's now or never. The car has had an engine rebuild, new silicon pipes, new swirl pot, new aluminium rad, new water pump. So leaks really 'shouldn't' be a problem. And now would be the time to use it, when there is I water or rust in the system.
Still a no no?

Given the "pro's and con's" I'd go for good old tap water (or de-mineralised if you want to be posh) and a quality anti-feeze / corrosion inhibitor.
Oh, and where does it go, should I be topping up my computer

Is that designed to operate at engine temperatures?Oh, and where does it go, should I be topping up my computer

I'd also go with Chris. These are 'old' systems in terms of design. They all use a little coolant through evaporation, they often lose a little from tiny leaks from the many hose connections. They will need checking and topping up no matter how 'new' the components. My friend who is clued up on the Rover V8 engine simply asked 'why'! If it is properly assembled and maintained there should be no coolant problems. Normal antifreeze provides good visual evidence of a leak. Do we know enough about the temperature readings that should apply with a waterless coolant? Do we know enough about the potential long term effects on alloy and on seals?
Head off into the unknown at your own peril!

It blows out the overflow cos the pressure cap is in the wrong location 
:ducks for cover smilie:
Ok i'll bite... :ducks for cover smilie:If I fill mine up to the correct level (swirl pot full and midway between the header tank marks) then the car spits out a litre or so as soon as it gets hot. I end up with the header tank practically empty and the swirl pot half full. Spring relief cap is on the swirl pot BTW.
I'll duck now!
OK - in a complete 180 on this, Mike has spoken to the manufacturers and will now be trialling the product and measuring results on a variety of TVR's, including mine. Despite the valid concerns raised here I do like the idea of the product and I have the chance now to trial it. If I don't like it we can revert to traditional coolants very easily.
All the best.

I'd be a little concerned if the stuff is flammable. The coolant system was designed assuming effectively water was going to be used so issues with overflow or leaks catching fire wouldn't have been thought about. Having 10 odd litres of hot flammable stuff circulating the engine bay would worry me!
Be interesting to see how good it is though.

Well I just spoke to Evans. They say the most combustable fluid is brake fluid, then oil, and finally their coolant. They said that the temperatures reached under the engine bay are unlikely to reach sufficient heights to ignite the coolant which has a true boiling point of 195 degrees. Leakage onto an exhaust manifold they don't believe would cause a high enough temperature. They also said that in a 50/50 mix of regular coolant (water and glycol), the glycol is also combustable. And in a traditional mix it's the water that evaporates, so the mix will become more concentrated in glycol.
They said they've had no instances of fires in vehicles related to their coolant.
What do you think ?
