Correct answer
The engine’s cooling passages and radiator.
Between the engine’s cooling passages and radiator, where heat is transferred to air. The pump moves coolant around the circuit; with the thermostat closed, coolant may use a bypass depending on design. An expansion tank can be part of the system but does not replace the main engine-radiator route. In a wet-sump system, the sump holds lubricating oil and is not the main coolant route.
