Evans Coolants

[1000dollamitzy]

Hi Guys

http://www.evanscoolants.com.au/high_pe ... olant.html

Has anyone ever seen or used this product? it looks very interesting and am thinking of putting this in the $10,000 mitzy.

Would be interested to hear any comments from anyone who has any experience with it.

Cheers
Rick

It replaces the water, All good til you spring a leak or overheat on the track and need to top up/refill. Would mean having to carry a decent quantity of the stuff at all times, just in case.
Never heard of the product to offer any insight though.

It doesn't tell you what it is made of instead of water?
No proof of its claims?
I wouldn't be using it.

No you can just top it up with water no problems, it is completely miscible with water except that it looses it's high boiling point the more water you add.

But you are right there isn't a lot of info on it, so would be keen to hear from anyone that has used it as the concept sounds good and the science behind the theory makes sense.

Similar to this? http://www.trademe.co.nz/motors/car-par ... 838635.htm

yep, same stuff different manufacturer by the looks of it

Yeah be carefull, there's not much out there with as high a specific heat capacity as water and all of the corrosion is taken care of through the antifreeze. A lower specific heat capacity means the fluid takes less energy to heat up meaning the engine will have to pump it around faster to have the same cooling effect. The lack of pressure is interesting, as far as I know an increase in pressure increases the boiling point of water allowing your engine to run hotter and more efficiently but the whole system has to be made stronger to allow for this. It's good the new fluid allows for hotter temps without the need for pressurisation.

For that price it's not worth it for me, if you do use it, do so with caution.

One of the boys at work is using it in his race car. 6.0l v8 pretty much on redline when ever it drives, a drift car. Has only just put it in, so I will ask how he feels about it and get back to you. I was thinking about it for the surf, but i am unsure myself.

[snotgoblin]

My understanding was that the whole point of having a bled and fully sealed cooling system is to remove any air which would allow for expansion, boiling and therefore steam to form...

All of the boiling temperatures quoted (103 and 120) are at atmospheric pressure. Assuming sea level, as the higher you go the lower the boiling temp of water ...

All the talk of flash vapourising and the like seems a little unlikely in a fully sealed system?

Expensive too...

Yer I think the guys that wrote the blurb for this stuff also wrote most of the scientific reports for the global warming, opps I mean global cooling, opps I mean climate change debate..... which the rest of us just call the weather........

Anyway have decided to go with a good quality heavy duty long life coolant mixed 50/50 with distilled water as it seems like people that have actually used this stuff seem to be rarer than an honest politician

[mudlva]

Why distilled water?

[Smurf]

Good call. I think anything that is supposed to replace water, yet can be diluted with water sounds a bit suss.

[1000dollamitzy]

The reason for the distilled water is that i am being pedantic, in reality there are 120-150ppm of contaminants in regular tap water that when heated can drop out and cause deposits in the engine (have a look at the inside of a hot water cylinder in an area with hard water if you want too see what i mean).

Now this is probably not going to make alot of difference in my engine, especially with half of it being a heavy duty coolant, but for the sake of $5 worth of 1ppm water from the warehouse why bother taking the risk?? Especially when i have just spent 6k on a brand new out of the box motor

I can follow that.
