Evans waterless coolant!!!

Hi folks
Does anyone have Evans in their V8? And does it make a difference to general cooling and temperatures?
I've heard mixed reports and some specialists recommend it and some don't.
Thanks in advance

Gareth, lve not used the stuff myself but seen it for sale at lots of shows?if your cooling system is in good condition; rad not leaking, pump not leaking both fans kicking in around "80-90", and you have a clean coolant mix without sludge build up, if all these points are addressed you shouldn't have any overheating issues with a good quality coolant looking like Comma.Does anyone have Evans in their V8?

The stuff is about 10% less effective than water and antifreeze at getting the heat out off the engine- so you delicate aluminium v8 will run hotter when things get marginal , as will the oil. This is really bad news on an engine that can get trashed at around 110'c- even if the stuff does not boil. Its also a pain to remove all traces of the old coolant before you use it, costs a fortune, you cant top it up with water if you get a leak, and there are nasty rumours about its flammability. I would not go near the stuff. Something about fools and their money applies here.

Pretty much 5 Litres of antifreeze for £10 and water is free, this mix is:
1. Cheap
2. More effective at absorbing heat than Evans
3. Completely proven
4. Completely safe (unless you drink it)
5. Easy to top up with good old free water, which you can find anywhere
Evans Waterless Coolant seems to be very expensive and very will advertised, they recruited loads of UK dealers within 6 months of coming to the market here, all of which tells me there are big margins in this product.
If it was expensive and proven better that's one thing, but its expensive and comes with quite a few draw backs.
When you balance all that with the fact a water antifreeze mix does the job brilliantly, it makes you ask why would you spend a huge amount of money on something that in many cases is inferior to the proven traditional solution.
In effect Evans is selling itself on solving a problem that doesn't actually exist, "If it aint broke why fix it?" comes to mind!
This makes interesting reading:

Obviously a rival but it raises many issues without any sales promo. It appears the heat conductance was far wore than I thought, plus its only neat antifreeze at best, not some new high tech' product.

I went with it been running with it for four years , and did notice slightly cooler running temps, but the main reason is my heater matrix, pipes that go to the heater matrix were all rotten, at least this stuff it won't corrode the internals. I havnt had a prooblem with it , but like anything some people will tell you no and some will tell you yes , pays yer money and takes your choice
I'm liking the link to the No rosion website, but I am equally intrigued to how their findings are founded. Any company that sells a product that suposidly does an independent unbiased review is somewhat sceptical. Just because its posted on the web, does not mean that its true.
By virtue of this, any company that sells a product has to be able to back it up, without being able to they are liable to be prosecuted for false advertising. In this day and age, don't you think we might have heard something terrible about this company, if there was indeed a serious issue? Everything that I have found that is against this product seems great on paper, but there are no hard facts to back it up.
There is but one question I do have. If this product is so terrible, why has Jay Leno decided to convert all of his cars over to this stuff? Yes I know he endorses a lot of products, but a man with this much power surely is in a better position that we are to decide if it is better or not. This to me speaks volumes.
I am by no means biased towards the product and many would argue about re-inventing the wheel. But Technology moves on and so should we.
You may ask why manufactures don't use the product in their cars. Cost! The same reason that none of the fasteners are made from stainless steel, they don't need to be as steel can do a great job and cost less.
On reassembly of the Cerb, I intend to use this straight out of the box, the idea of having a low pressure cooling system really appeals. This also does away with the conversion problem as there is no water in the vehicle at all.
Perhaps in a few months time I can give a review of the stuff and weather I intend to maintain the coolant in the vehicle.

You need to be very specific here as to why its a bad idea on an Rv8- any product that is poorer at removing heat from an engine and getting it to the outside world is a bad idea on the RV8- this engine likes to run cool and shifts its liners if it gets too hot, and water / antifreeze is still a much better medium for this than Evans and even Evans themselves admit the engine will run hotter. I dont care who uses it, just the science behind it.
This discussion was done to death on the club forum last year. Some who do use it get very heated (
) and will not have a word said against it. But many disagree. Two diametrically opposed camps who wont budge and the link on here was also on there.
My only question is: if its so good, why don't manufacturers use it? Price is not a an issue on cars costing £40k upwards. Seems they're not convinced.

They did put the stuff in a Triumph TR6 on wheeler dealers to try and prevent an overheating issue- but of course the truth here is a water overheating then boiling issue, so yes it would fix that as it wont boil dry. An old cast iron engine like that is a lot tougher when it comes to being cooked, and probably would not bat an eyelid at a constant 120'c so no harm done.

^^^^ This, I'm a non-believer. I read on other circles some guy with a TVR was trying to tell me it was great and he could even notice less heatsink in the car as a result. I suggested it may be placebo and he went for my jugular ) and will not have a word said against it. But many disagree.

Some refuse to be educated.
