If water has no heat transfer, than I guess all of those people with air to water intercoolers are fubared, as well as those people who heat their house based of the principle of water being able to absorb and transmit heat.

Sorry, as Sommer said, I am The Alchemist, and when something is said like that, it causes me to laugh.

Yeah, I mean don't you guys watch Pinks All Out? Rich will flex on your *** if you run anything but water in your car.

Haha seriously...

I cant believe that you said that watter has a higher boiling point than coolant. That was a typo RIGHT. Coolant has a higher boiling point than watter . At sea level watter boils at 212* and a 50-50 mix of antifreeze boils at 226* (at atmosphere). Clearly you made a typo I HOPE.

Boiling point of antifreeze under preasure and at atmosphere

antifreeze at Atmosphere

% of mixture 40 50 60
BP 222* 226* 230*

With a 15 LB CAP

% of mixture 40 50 60
BP 260* 265* 270*

Hope this HELPS (Note) never run a modern computer engine with straight watter it upsets the sensor readings.

Check out the less panic filled links below on the result of mixing the two different coolent products together.

There are rumors that mixing DEX-COOL with standard green (non-OAT) coolant causes a chemical reaction that produces sludge in the cooling system. According to the DEX-COOL manufacturer, however, "mixing a 'green' [non-OAT] coolant with DEX-COOL reduces the batch’s change interval to 2 years or 30,000 miles, but will otherwise cause no damage to the engine."[10]

there is ALOT of fail in this thread about heresay and myths that.....well honestly who the **** knows where all this is coming from.

green will not mess up any sensors on a "computer engine" whatever the hell that is. water and ethylene glycol will boil at diff temps based on relative elevation and the pressure that the system is under.

god will not smite you if you mix coolant. you do not have to use a sacrificial annode anymore.

cliff notes: know what you are talking about

I LOL'ed at this.

in canada its the freezing point of coolant that matters
normally i think dexcool at 50-50 mix freezes at -40 (celcius and fahrenheit)

and using straight water is ok (in summer) but it doesn't have the anti-wear additives in it, obviously

I just do what is recommended on the type-the mixture depends on how I feel. Winters here where Im at are mild. I dont do Tap water cause its barely suitable to drink. Use whatever that wont cause electrolisis in the coolant system-Distilled I think. On my older Brass/Copper exchangers would even have a Anode to help with the exchanger against build up of grunge in the system.

Heat transfer with plain water is greater than water mixed with antifreeze. Water is awesome for heat transfer but it contains nothing for waterpump lubrication or rust prevention. Antifreeze contains both, and so do other products. Freezing point and boiling point are different subjects.

Dexcool's promise is 5 year/150,000 miles per fill. Dexcool's reality is rot and rust in systems that are not airtight and for people that wait too long to check their coolant level and condition. Believe the hype or don't, but don't ignore your cooling system.

Dexcool does not turn into and alien creature that destroys your radiator when mixed with another color antifreeze. What happens is that you lose your long-term protection and must revert to the standard 2 year flush/fill to maintain standard protection. The main point, however, is know that the hell goes into your car and use THAT kind of coolant/oil/gear lube/ATF. Don't be a blockhead. Pay attention.
