C5 16v 2.0L coolant

Post by Smarty2 » 25 Aug 2017, 19:51

Hi everyone, taking my C5 over to Germany next month and was thinking of using a waterless coolant by Evans: https://www.powerenhancer.co.uk/shop-by ... evans.html
However I am unsure as to how much I would need for a complete swap out? I'm quite impressed by this waterless coolant as it has a boiling point of 180c and a freeze up below -40c! Any thoughts?

Has "standard" coolant ever let you down by not being able to cool your engine ?

Some things seem like a good idea until you think from the other end of the Need Graph

Well no, but water is a corrosive and this waterless fluid doesn't need to be changed, well at least for 20 years! And I still would like to know the amount needed "if" I decided to go down the Evans route? :)

A big part of the chemical make up of "Coolant" is corrosion resistors and Ph levellers. What problem are you trying to prevent ?

What you put in your car should not cause corrosion................

If you dig out the MSDS sheets for the product, you'll probably find that your waterless coolant contains . . . . water. There may be other chemicals there, but if it needs to be liquid, then guess what...

Forget it. It's a marginal and expensive con.
Just use Peugeot-Citroen 'Pro' coolant. It contains all the protective ingredients you'd ever need.
Other good makes also available.

What is commonly thought of as anti-freeze will also raise the boiling point when mixed in a suitable ratio with water. In addition it will contain corrosion inhibitors designed to stop, err, corrosion for at least three years, five if you go for coolant with OAT inhibitors. In practice you can leave it in longer if you haven't had to top it up with ordinary water. And if you have topped it up with water then you can drain some of the over-diluted coolant out and then top up with neat coolant. If you have to top up the waterless coolant with water then the whole lot is contaminated and will need to be replaced.

For ordinary cars waterless coolant is a solution to a problem that doesn't exist.

Let me repeat, 'waterless' is a con, aimed at those eager to part with their money.

Right so it's really only a con for it's intended purpose in race engines and one assumes they think they can leech over into the general market and con us too? Ok got it, thanks.

BTW Noble and others must be idiots?
Power Cool 180° is the coolant of choice for many professional racing teams and performance car specialists. For manufacturers such as Noble, no other coolant offers the performance of Evans waterless coolants
:rofl2:

Someone on the forum researched this heavily in the past and actually found that waterless coolant had undesirable characteristics for our cars. Sorry but I can't remember who or which thread. Hopefully they will read this and put up a link.

No, why would you think that? It's the exact opposite. In conditions where the cooling system is under intense stress it gives just a little more heat transfer ability compared to water/anti-freeze.

It's not a con - it's just not necessary. As an analogy, you could put 101 octane petrol into an ordinary petrol car designed to run on 92 octane but you wouldn't get sports car performance out as a result.

If it works as claimed, and lasts for 20 years, it's cheaper than standard coolant.

I like the big bold IF that would be if you kept the car for twenty years, if you didn't have to drain it for any engine work, if the system didn't get damaged by some misfortune of use, etc. etc.

It's unlikely a modern aluminium and plastic radiator would last twenty years and not need replacement.
