Evans Waterless Coolant....
Anyone ever try this stuff? I was just reading about it on line and it says it removes the threat of corrosion, electrolysis, liner pitting, detonation and over heating. I was just wondering if it's any good or just another snake oil?

This stuff has been beaten to death on every motor vehicle discussion board on earth. It's a classic examples of a miracle product that's not really better, just different. They spin it by claiming that it cures all sorts of ills, but these are things that don't happen in the first place.
Of your list of 'advantages' (removes the threat of corrosion, electrolysis, liner pitting, detonation and over heating) conventional coolant already does all those things. When it comes to closer examination, the Evans coolant is significantly worse at removing heat from an engine than conventional coolants. A step backwards for cars that are borderline to start with.
One of their biggest smoke and mirror claims is that it allows the coolant system to run with no pressure. Many potential users believe this to mean that coolant does not expand. False- it expands pretty much like any other liquid when heated. Evans achieves a pressureless coolant system by modifying the vehicle to prevent pressure from building- drilling a hole in the rad cap or just leaving it loose.
Looking at the cost of the required flush, the gyrations required to prepare the system and the outrageous cost of coolant itself, balanced against the probability that at some point in time a 'top up' will be required or aleak might occur, no farquing way does this make sense.
Aside from that- ya great stuff.

Thanks for the great reply. I was afraid that it was just hype. I have never heard of that stuff before, now I know why. Thanks again. Guess, I'll just stick with Prestone.

For fun I watched the Wheelers Dealers episode where this stuff is being pimped. No idea who the idiot on screen is, but he starts with a statement that 'old engines run hotter because of modern unleaded fuels'. They should at least hire someone that knows something about engines. Yeeesh.

I use this stuff in one of my Vettes - for a very specific reason. Its a '72 survivor - all original hoses - and i'm scared to death to drive the thing for fear that pressure builup in the cooling system will burst an original hose while i'm out stretching its legs. The Evans coolant - as advertised - does not build up any pressure within the cooling system. None. Therefore I can drive the car with a bit more confidence that it'll make a round trip. It is a big block, auto, a/c car - which always have a tendency to overheat - this one does not overheat either.

Thread hijack alert:
In all seriousness, the Slick50 SPRAY lubricant is great stuff. I've used it in coin machine restorations, vehicle/mechanism locks and hinges, for shop vices and tools. Never had an issue with it gunking up like silicon sprays. Beats the crap out of WD40 for everything except for what Water Displacement Formula #40 was designed for: displacing water.
Never used the engine additive and don't care to. But that spray stuff is great, IMO.
Not affiliated; don't work for 'em; nobody pays me to say this, etc etc. YMMV

I have 100% ethylene glycol coolant in my 1968 Corvette, my 1995 Thunderbird and my 1994 Cadillac Seville. Absolutely no water.
The Evans coolant is propylene glycol. A good reason for using propylene glycol is that it is not poisonous. You can drink the stuff. Look at food additives..candy bars and you'll see propylene glycol. Ethylene glycol is just as good but it's extremely poisonous and has a nice sweet taste. Dogs and children can be accidentally killed and there are cases were people added it to orange juice for people they wanted to kill.
Ethylene glycol (green stuff) is not as efficient of a coolant as water, but it's just about as good. Ethylene glycol boils at about 350 degrees F (?), so with ethylene in the coolant system you won't see cooling system pressurization. When I drove my new ZZ4 in my 68 for the first time, I just hand fitted the cooling hoses on the water pump and drove it knowing that the system would not pressurize.
The main advantage of a water free cooling system is that there is no corrosion ...no radiator leaking, etc. When I removed the factory engine from my 1968, I had no water in the radiator since about 1974. There was NO rust in the engine water chambers...a thin white layer of silicates was in the water chambers.
WWII Mustangs and Spitfires had liquid cooled V12 engines. They were the fastest internal combustion engine powered vehicles ever. They had NO WATER in their cooling systems...they had pure ethylene glycol coolant.

I'm glad you've had success with just coolant. Just a few notes:
- I would not recommend drinking propylene glycol. You may see it in food items as an additive, but be assured that this is in small quantities.
- Ethylene glycol is colorless. They add a dye to it so you can distinguish it from water.
- Ethylene glycol and propylene glycol have less than 2/3 the heat capacity of water. Water is a much greater coolant because of this fact. This is why some have noticed an increase in their coolant temperature when using Evans.
- All liquids experience thermal expansion - you will see pressurization as your engine temperature increases. You also have a water pump, and in a closed system such as your coolant system, this increases the pressure in your engine as it forces water through your block. Is your radiator cap not threaded down tightly?
I can see many systems that could operate just fine with 100% coolant. But, I believe our systems are designed primarily to remove heat. Water is your best agent to do this, coupled with ethylene glycol for boiling point elevation.
