[B]Refrigerant runs through the evaporator not coolant. Coolant is the substance used in the radiator and engine for engine cooling. Refrigerant is used in the a/c system for cabin cooling.

Thinking about this more I realized how stupid I am - of course I knew the function of the evaporator and that hot coolant couldn't possibly run through it to cool the car! What an idiot! It is a testament to the class and diginity of the people who replied to this message that they didn't point out my stupidity to me but instead chose to educate me. Thanks guys.
