Coolant...Evans or Ice ?

Submitted by DaihatsuDave on

Forum: 

I'm tempted to use the Evans coolant recommended by Bob but getting rid of all the water is a pain. I'm also interested in this stuff but its not cheap -

Any opinions?

Was also thinking about it.

Was also thinking about it. But then i asked myself there has to be some drawbacks. Otherwise i would think manufacturers would certainly be using it as they love the maintainence free and sealed for life concept where possible.

It will run bit hotter, that's certain. How much more i'm not sure.
Whilst that's not a problem if the engine mapping is designed around it, What i think could do affect on a standard car is air/fuel mixture due to the coolant temp sensor. Also the gearbox cooler less effective.

I recently drained the YRV 3 times with pure water (di-ionsed), Old stuff was perfectly clean anyway and radiator looks spotless inside. I filled with 2 litres of concentrate 5 year longlife Red. Normally i drain each year anyway, corrosion is not a issue with good antifreeze 35-50% concentration and soft water.

Will have to do more research on waterless. Draining all the water out is a pain, would need that evans pre-treatment stuff as well

I was thinking about Evans on the GTti as I'm building the engine so it's 100% dry, also the car has no heater.

Reagrding that ICE stuff,

Reagrding that ICE stuff, it's just like Redline water wetter i expect.

No real gain when you use a normal 35-50% antifreeze mix.

It does work but to get the max benefit you have to run pure water or a very weak mix of antifreeze.

Im running about 40% antifreeze concentration at the moment, the old stuff i drained did seem very red and could well have been stronger than 50% concentration.

Hard to say if i'm running cooler now, Gauge is a bit lower, but then the temperature outside is much less of course now since that mini heat wave.

I'm always sceptic but you

I'm always sceptic but you never know there could be all sorts of politics involved....old Mr Evans Wink (ex Area 51 worker maybe )teaching the boffins and critics etc real Science? Biggrin

Engine Ice do say this -

A note on modern street automobiles:

"Newer model street automobiles are equipped with a massive amount of electronic and computerization equipment to keep your passenger car operating at what the manufacturer wants the engine to operate at. One analogy we use, and we agree it's a bit simplistic, is that even if you filled your radiator with ice cubes, the computer system would hold the thermostat and monitoring equipment until it reaches its pre-programmed operating temperature. Bottom line is, you'll probably only reduce the overall temperature by a couple of degrees due to the thermostat opening and closing or "feathering" in order to maintain its preprogrammed and desired temperature. Keep in mind; we are talking stock, unmodified passenger cars, not racing cars
If you wish to use Engine Ice Hi-Performance Coolant in your passenger car in order to take advantage of its purity and environmental aspects, no problem at all. For the environmental reasons alone, we encourage you to use Engine Ice Hi-Performance Coolant. Read more about the environmental aspects here".

Great minds Nathan....Recently got longlife red coolant from Pages £2.83 +vat a litre Smile for my sons Punto (first car). Got distilled water too from Asda of all places reduced to £1.50 for 1.5ltr. Also going to add some Forte coolant conditioner. May do the same on the Turbo.

Maybe all these coolants ...Evans, Engine Ice etc etc may all turn out to be like the "Snake oils" out there and be aptly named "Snake Baster" or "Snake Gravy"! ha ha Biggrin
