| Anyone ever use this? Not sure of the thermodynamics. Understand the no-boil aspect.

| I'm waiting on some others to comment on this stuff. I have seen several frog choking's and a few barn burnings, but I have never heard of it. It will be very informative to learn about the new product...MD | |

| With no pressure to control the boiling point temp how do you keep it from being too hot? I see a local bike shop sells it. I'll have to call. | |

| The way I understand it, and I could be wrong, with no boiling point, you build no pressure... with no pressure, you can dissipate heat easier and does not turn to steam... the "water pump" is not designed to move steam, just liquid, so you get better fluid movement, hence, better cooling... even if I'm wrong, it sure sounds good... | |

| A cooling system is under pressure so it can exceed 212F without boiling. The boiling point of the fluid is not an issue since pure water pressurized will not boil at 230F.
The issue with temp is the metals in the engine and oil can't stand it. 250F without boiling is an issue. That blocks gonna crack if something else does not.
I personally would not buy any of the gimmick coolants. I worry about freezing temp -- I don't want to wake up in WV with a frozen Rzr radiator or engine. | |

| After a little internet research, here are two answers to that question and may add a little light on this post.
Straight from the web:
A 50/50 mixture of water and ethylene glycol antifreeze in the cooling system will boil at 225 degrees if the cap is open. But as long as the system is sealed and holds pressure, a radiator cap rated at 15 psi will increase the boiling temperature of a 50/50 coolant blend up to 265 degrees. If the concentration of antifreeze to water is upped to 70/30 (the maximum recommended), the boiling temperature under 15 psi of pressure goes up to 276 degrees. ok, a bit of a science lesson. water boils at 212 f right, now make that a 50/50 mix of anti freeze and water, that boiling point goes to somewhere around 245 to 250. now add a 15 psi cap. every pound of pressure on the fluid raises the boiling point another 3 degrees, so with a 15 pound cap, add another 45 degrees. so we are now at 290 to 295. does this help you at all? if that gauge gets to about 280 i would turn the heater on high with the fan on and roll the windows down. then figure out what is going on.
It is kind of confusing how the psi changes the equations. Kind of like in our fire service we are taught that water boils at 212 degrees at sea level where the atmospheric pressure is 14.7 psi or gravity pressure...MD | |

| Good info! You make me remember my road racing days and oil cooler selection. Radiator/thermostat cooling indirectly controls head/cylinder temps, as well as, oil temps. I like to find out how Evan's controls temps within the range of engine design applications. No water vapor should be a good thing. | |

| It's no different than cooking green beans. You can cook them all day on the stove top at 212F (boils) or put in a pressure cooker and cook in 20 minutes at 270F. Here's another interesting tidbit -- 100% distilled water cools better than antifreeze at any mixture. The issue is water is corrosive and it freezes... From internet to explain: Why a rich mix gives less cooling:First of all, in this article, we refer to the stuff you buy simply as “antifreeze.” It comes under many different trade names, and for automotive applications, is usually ethylene glycol. We'll just call it “antifreeze.” Now if you've ever poured the stuff into a radiator, you no doubt observed that it is much “syrup-i-er” than water. That is, it has a much higher viscosity. This means that it will not flow as fast through the system as water, and the cooling effect will be less. Further, the specific heat of antifreeze is less than that of water. This means that for a given temperature change, the antifreeze will carry less heat each time it circulates from engine to radiator and back. So, if the mix is too rich, the cooling efficiency will be reduced because (1) the flow rate is less, and (2) less heat is transferred per cycle of the coolant. So this means don't go crazy with antifreeze. 50/50 mix is fine. | |
