Evans.

I know some of us are running with the Evans waterless coolant, I wonder if they have any comments or experiences they'd like to share ? Martin.

are you thinking of using it

I'm looking forward to using this,
have to fix the leaky rad and find the source of the coolant sloshing around in the vee before spending that much.
Amazing stuff, saw that it was installed in one of the Stag engined estates at the NEC last year.

Don't know Dave, still trying to find out about it. I've read all the bumpf, but not yet convinced that it's not too expensive. Martin.

[martin]

Bump ?

When I saw the title I thought it was going to be about the shop for larger people

[Richard Saunders]

A friend uses it and though he's not done huge miles since, he reports that it works just fine. Running temp is about the same as before. The biggest challenge is purging the water...

Hi Martin,

I have the evans coolant in my car and if you look into it I think you will find that the price has dropped. When I first priced this up it was around £160 but I bought the coolant and prep fluid at the restoration show for £100. (1.5 Gallons + prep)

When I installed it my heater did not empty correctly and in the first lot I used the water went into the coolant making it useless. I found this out as evans checked it for me at the NEC and it had 17%water so I had to replace it! But hats off as evans gave me the replacement fluid free.

I have been running it for a while and the weekend before last I did a trip of around a 130 miles and he temp never went above 80 deg but this possibly due in part to the cold weather we are havung, I also run the external belt driven pump.

I was very keen on this stuff until a) I realised quite how much it costs and b) someone made the comment that on a car with conventional coolant if it starts overheating then you can usually smell, or even hear !, something and may, just, avoid the worst damage. With Evans and their 160? degree boiling point, I guess if things went wrong then the temperature would carry on rising and rising until some damage to metal occurred.

Maybe the smell of a conventional coolant boiling is not such a bad thing after all ?

I'll watch further replies with interest.

Cheers

You can read a lot of good stuff about it but I'm still not comfortable with the idea. it may not boil until 160 but the engine will still get very hot if there is a problem which will result in damage.

Not for me.

With the amount of times I seem to have to disconnect one coolant hose or another it isn't for me - it would cost me a fortune in the long run!

search for Evans waterless coolant thread

• Evans Waterless Heavy Duty Coolant will last the life of the engine, as long as it does not become contaminated by water.

But it is Hygroscopic Describing the ability or tendency of a material to take up moisture readily from the surrounding air or other moist materials.
So A perfect system will be required.
If you Drain the system it needs to be put in a sealed container then it could be reinstalled.

I think for a brand new engine the benefits are quite compelling assuming there was some means of detecting an overheating situation.

However, in a used engine with sludge and rust in the water ways I am not convinced that it is possible to completely remove the water therefore rendering the Evans fluid useless.

A couple of questions to those using the Evans coolant:

1. How do you know if your cooling system has been completely emptied of water or at least enough to ensure the Evans coolant would be effective?
2. Does the Evans coolant give the same reading when testing the strength as conventional antifreeze/water mix?

With the later question I would hate to collect my car after a service to be told ‘Hi mate you your Stag didn’t have any antifreeze but don’t worry we flushed the system out and refilled it. The funny this is, the water that came out was a strange colour’

There's a lable that goes on the filler cap that warns not to top up with water.
I'd want to be carrying some spare stuff in case it was needed..

A friend of mine in the Porsche circles sells this stuff and seems happy to use it in his race cars (well, in Porsche 996s).

As for price, let's not forget modern coolant is not cheap (the 10 year stuff in the Ford is around £8/litre, OK you only need 5 to fully fill my car (a 3.0 Mondeo V6) but it is still not cheap.

[Off Topic]For the naysayers saying I am wasting my cash, consider this. At 220,000 miles I had to change a coolant hose (it became a little hard and was starting to crack). What the inside of the engine like after all those years of service? Absolutely spotless. I hate to say it, but none of my cars (even the Stag after I flushed the living daylights out of it) where quite that clean on the hoses inside (the Pug was close, but that rigorous coolant changes every 3 years (all alloy enigne). Consider the Mundaneo until the hose went had no change of coolant (Ford say it is for life/10 years), it is food for thought).

I too am interested to hear about the experiences of Evans coolant within the Triumph circles.
