Waterless Coolant?

I was watching that Wheeler Dealers show one Saturday morning, and they talked about this waterless coolant product:

Evans Cooling Canada

Benefits:
- 180C Boiling point
- Because of high boiling point, cooling system runs unpressurized
- Eliminates cooling system corrosion

Cons:
- Expensive ($60/gallon)
- Can't add any water (unless in emergency)

I always wondered if something like this exists, and now I know that it does. I've noticed from looking at inboard boat engines, since they run unpressurized (cooled with straight sea/lake water) the rubber hoses stay in great shape.

I'm thinking about running this stuff in my Mazda and Mustang. Does anyone here have any experience with this stuff?

No experience with it, but this almost reminds me of Redline's Water Wetter.

personally i wouldn't bother. As long as you change your coolant somewhat regularly, coolant itself won't "fail". The only time coolant would fail is its missing. (leak)
And if this stuff really is that good and is the only thing from keeping your engine from overheating, then its likely compensating for something else thats gone wrong in the cooling system.
And if for whatever reason your engine is getting anywhere near 180C, its great this stuff won't boil over but the fact that the engine is up at those temps, the gauge will still be in the red zone and damage can still occur.
Hose won't get brittle and leak becuase of coolant. It will brittle because of age.
Oil dripping and soaking hoses will swell and soften over time.
$60 a gallon is nuts. Just make sure the rest of the cooling system is up to par.

Then again, maybe this stuff would be good in boat engines. I have no experience with boats

What you have said is all incorrect. That stuff is great, my dad has swapped it into his 5.0. Water causes corrosion. The heating and cooling of the water causes expansion, which causes hoses to break down. Also, you no longer need a coolant overflow, as you do not get the same thermal expansion you do with glycol/water. As long as nothing contaminates the Evans coolant, you should never need to change it. Should also let your cooling system run MUCH better, having far less issues with water pumps, heater cores, etc. This stuff is even mentioned in the text books for on and off-road diesel engine mechanics. Its going to become more and more common. Absolutely requires a complete flush of your cooling system to change it over though. I believe you can't have more then 4% water in the system.

Redline water wetter is more like a lubricant for the water pump so you can run straight water without it causing the metal to break down.

i'm such a skeptic. I've seen so many products over the years and when i seen that video it looked like such an infomercial.
I'm not so much doubting all its benefits but more whether its necessary.
If it runs at such a low pressure, where a reservoir isn't needed, i'm not so sure if thats a good thing. I always figured pressure is needed to maintain good coolant contact to the cylinder walls and other hot parts to take away the heat and also to have good coolant flow.

Just wondering, when your dad swapped it into his 5.0, was he having cooling problems or just as a maintenance thing?

No. Vehicle cooling systems are pressurized to raise the boiling point of the coolant/water. At 15psi (typical of cars), the boiling point of water is roughly 125C.

Read: Boiling point - Wikipedia, the free encyclopedia
yes, thats the obvious answer.
I had a look throgh some of my old text books, where i thought i read pressure would help flow and coolant contacting etc. Couldn't find any of that. So disregard my last post

In order for this product to work as designed, I take it you would have to be very meticulous in removing/draining/flushing the old coolant in order not to contaminate this stuff. This is also assuming you have no head gasket problems etc.

Correct or no?

Yes, on their website it states how much water you can have in the system, I havent checked but I am pretty sure its around 4%.

Just an upgrade. Ability to remove overflow to clean up engine bay, and keeping hoses in good condition. Evans Waterless is making a big name for itself in the trucking industry.

Yes, the trucking industry. This isn't brand new.

A lot of technology from racing and commercial industries make their way down to passenger cars.

IMO, if it ain't broke don't fix it. I can see how it'd be of benefit for race cars and HD equipment though.
