In the engine cooling system, between which components does the pump drive the circulation of coolant?

Question

DentroTest · Accepted Answer

The water pump or cooling pump is the mechanical element in charge of forcing the continuous circulation of the coolant through the engine's closed circuit. It is placed strategically to draw the cooled liquid from the radiator and send it under pressure to the water chambers (cylinder liners and head), where it absorbs the excess heat produced by combustion. The lower sump takes no part in the coolant circuit, because it stores the lubricating oil. Nor is the expansion tank the destination of the pump, because it serves to absorb the variations in volume and pressure of the liquid, and the pump does not act by pumping directly and exclusively between it and the radiator.
