Waterless coolant
 

What's the SP with these ?

I'm going to do a coolant change in the S1, and given the lack of mileage she does I'm thinking that using waterless could be better rather than water based, but haven't heard much about them.

Pro's and con's ?

It's over priced shit. Don't waste your money on it like I did.

My mate ran it in his Evo powered 205, boiled it several times. I wouldnt bother with it!

use good old distilled water 50/50 with antifreeze

I know several lads lately that switched from standard coolant to evans waterless coolant and swear by it no more pressure build up or overheating

my uncle runs WC in his dolomite sprint which now NEVER overheats and thats running OE rad and fan too and he drives it plenty too

Very good stuff does what it says. My car runs hot but now it runs hot without the pressure. I can take the header tank cap off with the fans in and the coolant doesn't move.

Conflicting views !

Maybe need to do a bit more digging around....cheers though guys !

I think a common sense approach needs to be applied to this stuff, if you have issues of a car overheating then theres a fault so rectify that first and then use WC as its not a cure for overheating, but if you have the budget to install this then I see no reason not to

That's my view Steve - no leaks or anything, so I might give it a go

Another advantage is it won't rust any internals.

I am interested in in from the no corrosion point of view! as the CVH block can rust! this is suppost to stop all of that! also boiling point is 180 not 100!

Never though of using deionised water

I use it in the Cosworth with no problems at all :-)

Don't forget to use the prep fluid.

It you don't use the prep fluid ( unless its a new dry build ) you will still have water in the system and you WILL boil it,
Awesome stuff to use,

the boiling point of water is not 100 if it's in a pressurised system - that's the point

i would rather have something that is going to blow of a load of steam if there's a problem rather than continuing to rise in temperature up to 180 as i don't think your block and head would thank you for that.

didn't edd china use it in one of there builds on wheeler dealers cant remember what car it was should give you a good clue how to go about using it

It also runs a fair few degrees hotter than water. Personally I wouldn't bother with it. It's also near enough £200 by the time you buy the prep fluid etc.
