Right, liquid transfer heat faster at the same temperature differences that gas does. Guess what temperature that coolant system is already at? Here is a hint, don't pull off the radiator cap when the car has been driven recently. You can't 'dump heat' into something that is hotter than you are.

If they want to dump heat via a liquid then need a new independent closed loop liquid heat transfer system. But no matter HOW good that transfer system is they can only get the other end down to ambient temperature.

I'm guessing the use of this system would require a re design of the coolant system or an independant cooling system dedicated to it to handle the additional heat load. I didn't mean to imply current auto coolant systems could handle the load.
