I imagine the plan is to dump the heat into the car's coolant system. It's the only logical place for it to go since liquid removes heat far more efficiently than air.

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.
