Waterless coolant

[Brenda1978]

So last week I blagged 8L of Evans waterless coolant off a sales rep. We have trialled some in our machines in work.

Drained and flushed out the system very well. The water was very good and not all brown sludged .

In went 5 litres , had the car running to get rid of any airlock. Added some more.

Went out today and the temp gauge used to show 83 to 85 degrees and fan would kick in. With this stuff in its running at 93 degrees. No expansion tak just a big ralloy radiator. Out for a run and after 10 miles it's 100 degrees. Limped home and gauge was 120. Took  the cap off slowly ..because you should be able to do so... and it spunked hot red liquid. In fact the entire lot came back out. Neighbours not happy about the mess.

Glad I didn't pay for the stuff. It was a cold day today so only spewed it's guts after the engine stopped. I tried it as when I have the engine running when parked by the garage this is poor airflow  to cool rad.

Maybe some water was still in the system. Now I only have lovely H2O

Not good mate

I looked at that a while back and didn't go for it in the end, I went for Prestone Antifreeze / Coolant Ready mixed.

Flushed and back-flushed twice and I changed the thermostat at the same time for a new 82 degree one and been out a good few times in it since including upto speed on the Motorway to get it really hot, and touch wood it's been good as gold

Did you run it up to temp when flushing and keep the heater matrix open to get that flowing?

Did you change the thermostat? is that fooked?

Isnt there a special fluid made by the company you have to use to flush and absorb all the water trapped in the system cause if you dont it does pretty much what you just described?

[BaileyMex]

Yeah I used holts speedflush

This stuff sounds a right load of bollox, reinventing water sounds like the kings new clothes to me, if you can't mix water with it then it's another stuck at the side of the road situation waiting to happen surely. A decent anti freeze mixed correctly is all thats needed but makning sure there are no pressure leaks and the engine is timed and fueled correctly simples.

I went for the Prestone because you CAN mix it with other anti/freezes and coolants and you can top it up with water, it was available as a ready mix, or a concentrate to mix with water.

The supplier I ordered from cocked up the order, and I ended up with 8 litres of the ready mix, so keep a small one in the boot just in case anyway 🤣

Wasn't sure on the Evans Waterless, so avoided it

Friend of mine uses the Evans stuff, he says it does run the engine cooler. But he used it from day 1 after the rebuild of the engine.

Your entitled to your opinion but unless you've used it, its conjecture and hearsay! If you know that you can't mix water with it, you carry a spare litre bottle in the boot - no stranger than carrying a petrol can around! It is a fluid that has a higher boiling point compared to water, doesn't have to be run under pressure to stop it boiling so likely will suffer less if a 'pin prick' leak occurs. It doesn't age, nor does it freeze. I haven't long term tested it in my car yet but so far it gets hot, it circulates and nothing has over-heated whilst running at fast idle for 30-45 minutes at a time so far. And a stone through a rad core is going to strand you anywhere, whether you use water or water free coolant!

Thats the one. The preparation process is very very important and its where most goes wrong with the product you have to get rid of every drop of water which isnt all that easy when you consider how intricate the inside of an engine and its waterways are.

Water is free, antifreeze is tested and proven and having worked in heavy engineering for over 35 years I have some expeirience so not really conjecture! 

If your peice of shit dumps all its coolant over the road and running repairs need to be made (Stone through the rad so crimping the core is needed/popped hose being shortend) then carrying 5-7 litres (Over £50's worth) in the boot is really out of the question surely as a get you home, my peice of shit has done it once or twice but luckly the water board place taps around the country so a lash up and fix is not costly and getting the turd home is generally easily done and all part of the classic car ownership expierience. 

My mk2 has a stant radiator cap that releases at 18psi (Tested) and my coolant system is well maintained and will hold this pressure easily, there fore a rough calc is that every 1 psi in the coolant system raises the boiling point of water by @3 degrees celcius so approx 150 degrees before my system boils over so as long as my system stays pressure tight i'll be ok as generally runs at 88' unless i'm kicking it's head in then it may creep to 94' as for freezing it won't with 40% glycol that also acts as an inhibitor. 

As for my opinion, kinda fact based with expierience and not just running it up in the garage where as yours is built on hearsay, conjecture and reading the advert. #kingsnewclothes 😁

So,  bottom hose off and flushed all warerless coolant out. Refilled with Peckham springs finest and back to her usual self. 

Glad I had the Evans for free, expensive stuff.

I tried Evans too.

It was on a fresh built engine so no issues with residue water.

I ran it through summer and to be honest it always ran hot 95 Deg + sometimes. 

I knew everything was OK rad, stat etc as everything was new.

In desperation I drained it and filled with water/antifreze mixed to correct ratio.

It ran bang on middle of temperature gauge in all weathers from that point onwards.

Im sticking with water/antifreeze mix from now on, it was an expensive lerning curve, but if you dont try you dont know I suppose.

Having said all this I do know many top end cars run on it so I suppose it does depend to some degree on the car/engine etc.
