n: on an engine, the tube or tubes through which engine coolant is circulated. These tubes bend back and forth several times so that the coolant will have plenty of surface to contact as it flows through them. Very thin metal plates (fins) are attached to the tube, which radiate heat in the coolant to the surrounding air.
