#1 Evans Waterless Coolant

Post by Barry » Mon Sep 03, 2018 10:49 pm

I’d be really interested to hear of experiences with Evans waterless coolant. Many of the well known top E-type restorers have started recommending it. My fear is that engines were designed for specific heat ranges, and exceeding those temperatures could cause longer term damage. Also, is this to be taken seriously as an anti corrosive coolant? That may have a bearing on its use in an XK engine as opposed to a V12. Let’s see where this topic goes.

You are right on the money.....it could mask a problem, and damage could occur. Stay away...great for race cars, not meant for street cars, despite the great marketing pitch. One other silly point......suppose your on the road, and a small coolant leak occurs. You quickly fix it, but a bit of the Evans is lost, and you must now re-fill your system. Hope you keep extra Evans in the trunk......if not, your screwed ! Can't mix Evans with water. Don't waste your money, as I said, its for race, or sealed engines.

Thanks, I share your views, but there must be someone out there who uses it, and maybe thinks it’s great. I’m certainly not going to use it, but the piece about anti corrosion could be Evans best pitch. Although, putting more inhibitor in with your water will do just fine! So is this just a marketing scam, giving the dealers an excellent commission.......

Forget the label for a minute.

Imagine someone comes up to you with a blank bottle and suggests you fill your occasionally electrically-incontinent old car engine with a flammable liquid alcohol.

Don’t do it! It just highlights the clever marketing for this product.

My two cents worth - i have had it in my S2 since I took ownership in 2014, following a thorough overhaul of the block coolant channels, and new block core plugs fitted.
It seems to be fine, and given the overhaul work it made sense to me to switch to waterless thereafter.
We completed a long (2700 miles)run around Europe this summer, and the car never had any overheating issues, even in stop / start traffic for an hour in 35C heat.
As to the question about topping up, although I took a 1 litre bottle of Evans with me, I read that if needs be, in an emergency, water can be added to the existing coolant without issue, although they do say that the system should be flushed and replaced with 100% Evans waterless asap.

Richard has been using this in his 3.8 FHC which had a full rebuild, new radiator etc. Although he doesn't spend much time on here, I know he is happy with it and hasn't yet run into any problems. The car runs well and has never hinted at overheating.

Same here - although in my case it has been water and anti-freeze!

Same here with over 50,000 miles through Europe over the last 18 years including temperatures of 42C in Biarritz - again it has been water and anti-freeze!

Evans did a presentation recently where they said their system was the same as in Spitfire's Merlin engines as they ran on pure glycol. I had to correct them and point out that although RR first tried glycol only cooling they soon found out that a mix of glycol and water gave better cooling. Evans' man was a little taken aback to learn that some of their sales pitch was WRONG :roll:

Evening gents,
I know the fairly firm view on the forum is the tried/tested and original anti freeze and water mixture and I hear the arguments about the flammability of the Evan’s coolant.
So, although many, many months till the decision needs to be made by me personally, I am intrigued by the idea of having a water and therefore corrosion free cooling system. Perhaps I’m overstating the benefit and maybe our corrosion problems are associated with poor maintainence in the past, but it’s kind of tempting isn’t it?
Cheers,
Rich

Hi,

I run waterless coolant in a performance Westfield Track Car & it's absolutely fabulous however that's pushing an engine to it's limit for an extended period of time so not quite the same conditions as a road going E-Type.

For my Series 3 V12 I run conventional Antifreeze / Water with a totally standard Cooling System & had absolutely no issues this year on either the 3000 mile road trip to Sicily (including a drive up Mt Etna) or the 1000 road trip to Angouleme & had no issues on the drive to Gibraltar in 2016 in 38 Degree Ambient.

Based on this I would suggest if the cooling system is in good condition there's no need for anything other than that recommended by Jaguar, particularly considering the cost of the Evans Treatment for no tangible benefit.

Regards,

Dave

Surprised they let you race the Westfield with any species of glycol, as it's dangerously slippery to others if you sprig a leak. Unless it was just track days I suppose?

If the Evans stuff is just glycol , then all you are buying is extortionately expensive antifreeze

I know this post is a bit old but does anyone on the forum have any experience of going BACK from Evans to old fashioned water? We have been asked previously and our V12 E-type currently has Evans "fitted", which was how we purchased the car.

There is no problem going from Evans coolant to water/anti-freeze - it is only the other way around that needs careful (and expensive) preparation. From their web site:

"In the event that there is significant coolant loss from the system during operation and no Evans waterless coolant is available to fill the system, water or water-based coolant may be used. However, repairs should be made as soon as possible, and the system should be drained, purged and re-filled with Evans waterless coolant."

Given the cost that will certainly be an 'ouch' moment! So go ahead and dump it, fill with water/anti-freeze and add a bottle of 'Water Wetter' which in my experience gives you an extra 5°C overhead.

Always useful to compare the market for coolants and I did just that 3 years ago after rebuilding the engine in my Series 2. I went for 4life coolant as it is a gycol based product supposed to last 10years which I doubt but,
20 litres cost GBP50 and even if it only lasts 4 years it will still be cheaper than replacing 50%mix Blue antifreeze every 2 years (with reduced disposal concerns too). I toured Scotland last year and in 2500 miles not a drop of coolant topup was required, another advantage it can be toped up with water in an emergency and this would not require the whole system to be replaced.
I have no connection with the supplier. https://4lifecoolant.co.uk/

Evans only warranty their coolant for two years. Nothing lasts for ever.
