There is an error in darthpup's logic; he is asuming that flow thru the radiator is at maximum. (1) Heater core is designed to transfer heat to passenger compartment, not cool engine that's secondary (2) Radiator is designed to eliminate waste heat from engine. If flow thru radiator is not limited at this point then increasing coolant flow thru it, rather than heater core, would increase heat loss. Assuming a radiator is more effective heat exchanger for a given flow than a heater core.
