Evans waterless coolant

[5paulmv]

Thinking on taking the plunge anyone on hear using it and is it any good trying to stop car boiling over in traffic que s any views appreciated

[BuzzBillsberry]

Theres a bit of reading on the subject here by a TVR owner

http://www.pistonheads.com/GASSING/topic.asp?h=0&a...

Worth a look I've heard various things about it but the good thing is I it's not under pressure and vastly reduces corrosion

There's also a link to Evans website one thing I do know it's about a £100+ worth of product to buy

Yes I have it fitted in my MK1 Vixen and 3000s and soon to add to the Tuscan V8 Ford 302 if your a TVRCC member I did a write up on the LBL Rally using Evans.
Really great product your engine will run about 5degrees hotter than with water but a small price to pay for zero pressure and no corrosion.
However your car should not be boiling like that in traffic so look at the cause and sort before fitting Evans.

It won't cure an engine with a cooling issue

As presumably Evans is a liquid how is it that it doesn't expend as it warms up? Is it me being wrong (probably!) but thought that was always the case but presumably it doesn't expand as it doesn't cause pressure in the system ..

Hi there Andrew I'm planning on using it in my ultima the issue I'm trying to solve is my car boils when in traffic we think its heat soak cos done a test on mt drive iff car on tick over it hits over 100 degrees in 10 mins but iff I remove engine cover it holds a constant 73 degrees so I was looking at coolant to try stop it boiling up ? anymore opinions or help appreciated

Pressure in the system with water happens when the water boils and turns to steam. Evans coolant has a higher boiling point than water (180C I vaguely recall) so shouldn't boil unless you have big problems!

Has anyone used this in a S6 engine TVR?

I know the S6 runs pretty hot anyway and wonder if the extra (if slight) temp increase would have long term adverse results - or would the pros outweigh the cons?

Hi Paul
it would be perfect for you I know of one race team where the water pump failed and the tem really rose very high and they where able to just fit a new pump and back on track with water they would have had to do a strip down rebuild as pressure would have blown the head gasket and water in the engine etc

Thanks for the reply Gadge - water expands and will start to pressurise the system before it boils (agree it expands much more when it does boil)so still don't understand it.

Yes you get a small amount of pressure but is so small when you take the cap off its like taking the top off a bottle of pop that has already been opened started to go flat and then had the top put back on and left sitting.
unlike a bottle of pop that had been shaken before opening.
I took the cap of to test when the car was very hot after scaling the Stevio and just a little pop and no overspill
Rather weird seeing the coolant flowing through the system with the engine really hot.

Strange but does sound useful stuff. I assume if doesn't freeze either - if so worth consdering but its expensive ...

Hi All.

I spoke to the guy on the stand at the Classic last week end, and it does sound like a very good product. You do need to run a solution through the system to remove any water and then fill with their coolant. But you are looking at about £180-£200 for the change.

Am sure Ed China said it costs around £80 for the complete procedure. Has the cost doubled in a matter of months?

I think the £80 is for a 'normal' car
I was quoted £150+, because the Chim' has 11 litres of coolant

I'm running 20 lts of water so not a cheap job to do

I think if you look at it long term as an investment on the car presuming its a keeper then that is saved in lack of corrosion whats the cost of a new water pump or a blown head gasket should it fail rest assured if your pump failed and the temperature went soaring then the repair bill would make £200 feel like loose change with Evans it will still rise but no damage.
I know its hard to swallow on something you cant see or show off down the Pub car park (hey look what I fitted)
But the party trick of opening the radiator cap with the engine running at full temperature with nothing coming boiling out is worth the £ IMOP

I would like to use this when I have my S6 upgraded to 4.3.

I know I asked before on this very thread, but got no answer - would this be problematic for an engine that runs as hot as a TVR Speed Six, bearing in mind the Evens stuff makes the engine run slightly hotter?

I might go down the road of upgrading to a 4.3 in my T350 as it just lacks the grunt of my Cerb and I have had loads of discussions with my TVR friends about Evans coolant and they are all against it,

Chris

Why not ask Dom his opinion on it assuming that is who you are going get the upgrade done with

I did email Dom regarding the coolant - he replied stating he's not sure. I get the impression that most TVR specialists haven't even heard of the product.

I just liked the idea of not having the water slowly eat away at the engine and componants...
