Waterless Coolant?

MSDS are your friend, it's mostly propylene glycol.

some other stuff to look at.

what about motor oil and other fluids effected by engine temp? this stuff runs hotter because it cant be anywhere near as efficient as water. water has the best thermal mass properties and really only anti-freeze is added to address the issues of corrosion when not in a freeze region where it also serves its namesake purpose.

the reason computer overclockers use water(usually as pure as possible distilled) is because water is massively efficient, some have actually tried straight anti-freeze and water runs the CPU cooler.

I never used waterless coolant, but never put water in with the coolant!

Bad idea is bad, what they want to run cars and crap HOTTER? ya um, headgaskets and the like are not going to like that.

supposedly it's only about 10deg hotter, i would be more worried about it pushing cylinder temperatures outside optimal ignition.

Small world. Evans, a neighbor, got his first "waterless" coolant from me - Dowtherm 209, which I believe was one of or perhaps the first propylene glycols for the masses. We used to buy it by the barrel. He thanked us later by giving us some of his early turbo start up / shut down lube devices.

I don't lay any claim to the innovations of where he took the coolant to after he left the yard. He is an absolutely brilliant automotive engineer. Just ask Corvette, who stole one of his patented applications after using it in a prototype Vette. I think the fact that Corvette thinks enough of his ideas to put them on the green light list makes it fairly clear what this guy is about. He sued Corvette, but it became a matter of attrition as opposed to justice, as law suits often go. I'm not clear now if Corvette ever did go to production with any Evans stolen ideas, but it was their intent to do so some years ago, hence the suit.

As near as I could tell from google, the Evans coolant is around 2 or 3 % water. The concept seems difficult at first, for we all have seen the late night TV MPG saving devices that if all used together, should yield enough fuel savings to cause fuel to bubble out the fill pipes. He is bucking a 100 plus year old concept of traditional cooling. In my opinion, his system works. I know personally a few people who have retro fitted his systems into new & used vehicles. They all rave about it, years into the installs.
That's my story and I'm stickin' to it.

The last thing I would try to do is use chevy engineers to show intelligence... if you ever look at anything they made, you would ask yourself what asshole designed this. (few, oil cooler lines that are not replaceable with out bending them outside of stock bends, putting a computer UNDER a battery, non sealed frame, with a lip bent up so salt can sit and rot the frame out, bolts too small to hold the exhaust on etc etc)

Also this rad fan runs less... okay I have not owed every car ever made, but from my experience, unless idling, my fans almost never come on, and those 100F + days... AC is on so they are on anyways... fail to see how the fan is going to spin less... If I drove longer distances I would rig up and hour meter to the cooling fan and one to the car, just to see how much time it spends on vs how long the car is on.

Also, yet to see a car / truck that is use, and had normal coolant changes... have rust issues inside.

Lifetime seems like BS to me, or we would see this is current production vehicles... anyway for them to say less maintenance is a +.

my 2cents.

owned the "pinnacle" of GM engineering, also known as a sunfire, i have may marks on my arms from replacing $20 and lower parts.

less maintenance is a +, not being toxic is also a +.

still thinking the refit thing is a little funky, special rad, special pump, special coolant. if your changing out most of the cooling system, of course your going to see some benefits.
