Yep we know it's cooling properties are slightly lower


It's not a little lower, its a good deal lower.

I'd betcha the difference in the coolant exiting the radiator with a 50% mix and without ANY water could not be measured without a labratory!


I betcha I could get my yz250 to run 10 degree's hotter (which it does) running pure antifreeze. Pure water has almost twice the heat capacity as pure Ethylene Glycol.

On paper is one thing but in actual use 100% ethylene glycol is the cats meeoooow.


BJ who do I have to get to tell you these facts?

ALL of my high school chemistry and physics teachers say the same thing, SO do ALL of my COLLEGE prof. ( some doctors).

There is no reason to run that extra 50% all you are doing is throwing more money at it.




If you are running your jeep in places where there is corrosive materials put on the road, there isnÆt much you can do short of buying a gold plated radiator.
