Evans Cooling

[mtenderenda]

I just watching a video clip on Jay Leno's garage http://www.jaylenosgarage.com/video/waterless-engine-coolant/1376127/
Wondering if anyone tried out a coolant called Evans. It doesn't corride the cooling system of your car, like standard 50/50 coolant does. You will never have to change the fluid, it will outlast your car. So has anyone tried it? If so, are you happy with it? The website where the coolant is www.evanscooling.com (http://www.evanscooling.com).

That right there oughta raise a red flag....

Evans is well respected in the automotive cooling area.

[lifespeed]

Respected or not, I am unaware of a legitimate protection mechanism for aluminum other than a sacrificial anode or a more-electronegative element in the coolant. Obviously this gets used up, so how can we have "lasts the lifetime of the car"?

Edit: Perhaps the Evans is not a polar solvent, like water. Still, I fail to see how galvanic corrosion between dissimilar metals (Al/Fe) would be mitigated without a sacrificial metal. But they do seem to be well respected.

Jay Leno is a big car freak, we all know that. And here he is promoting the coolant. So what do you really believe?

[na svt]

Road racers swear by Evans so there must be something to it.

I am running an Evans water pump, has a billet impeller and flows 30% more than stock it is a great piece and works great.
lifespeed: there is no corrosion because there is no water. That is the whole point to the Evans coolant, there is no water so there is no corrosion, there are no steam pockets and very few, if any, hot spots.
As Todd pointed out, tons of road race guys use it and swear by it. I would use the Evans waterless coolant except at my current power level and how I use the car I really don't need it.

I believe the laws of physics, chemistry and mathematics.

I am pretty certain I read an article about Evans coolant by Ray Bohacz in Hemmings Muscle Magazine a while back...and if I am remembering correctly, he wrote very positively about it.

[Joe Walsh]

Isn't Evans the guy who sued GM after he showed them his new coolant system.
GM said..."Nawwww thanks, but no thanks" and then promptly copied his idea for free......:rolleyes:
I've only heard good things about his coolant/system.

[lifespeed]

Apparently Evan's coolant is straight propylene glycol, with secret additives. Probably silicates and/or phosphates like are used in the usual antifreeze.

It may well be useful, but is not a new miracle elixir. Here is an interesting comparison (http://www.jcna.com/library/tech/tech0011.html) of the usual suspects, water, 50/50, straight propylene glycol, as well as the previous with surfactant (Redline water wetter, soap).

Dex-cool ring a bell? :eek:
Yea, no thanks...:shake:

Not really. Because there is no water there is no corrosion/rust so no sediment. The coolant does not get dirty. The additives don't fall out & seperate. It is really cool stuff! Because no water the boiling point is much higher so no need to pressurize the system!!!

Watch the short video with Jay. Cool tech! I'm going to try it.

[TooManyFords]

Just FYI, drag strips frown on anything more than water and water wetter in case a motor lets loose. I wonder what the properties of this is for cleanup purposes... Other than that, I think I'll be getting some of this for my other cars as I get them rebuilt.

[sailsmen]

Unless Evans has got an unknown additive their fluid will not remove the same amount of heat as 50/50. This is why their pump flows more, because it has to.
For a modern car using modern fluids I don't see the advantage.

[TooManyFords]

It is the radiator's job to remove the heat. My guess is that it will heat up just as fast as 50/50 and the radiator can remove it.

[TooManyFords]

Remember your laws of thermodynamics. This is a closed system, so unless the radiator cannot keep up, it will overheat. If it can, then there is no problem.

The laws of thermodynamics agree with Sailsmen. The radiator can only remove as much heat as is moved by the fluid.

[sailsmen]

The heat has to get from the source to the fluid and from the fluid to the rad.

Has anyone gone to the Evans site and checked it out? Or are we all basing our opinions off of Jay Leno lol?

When I first discovered Evans coolant 5 years ago and saw their water pumps, I called Evans and spoke to them at length regarding their products, all I can say is not only do they know their product very well, they were also very friendly and helpful. Maybe some in this thread should give Evans a call and end all of this silly speculation.

Just my .02

The short version is straight Propylene Glycol w. additives (Evans) may have some advantage for high boiling point, long-term storage cleanliness, coolant life, and corrosion (think Jay Leno's car collection here) it ultimately transfers 1/3 less heat than 50/50 glycol/water.

If you have no cooling issues with your use of the car straight PG coolant will work fine. If you encounter 100+ F air temperatures while towing your boat uphill, the engine and oil will get pretty hot with the factory radiator. PG reduces cooling capacity. If your radiator is big enough and you don't need it, fine. Also, if your engine is going to be running slightly hotter all the time you want to make sure the cooling fan isn't switching on at a low temp. Your oil will get hotter, too, so PG coolant is best used with a separate oil cooler so you maintain oil pressure.

Honda Blue antifreeze. I swear by it, use it in every car I own. 21bucks a gallon but it comes out the same way it went in, blue, clean with no rust, scaling or ph issues. All of their motors are aluminum so its safe for anything.
