An insert for a siamese-type internal combustion engine that separates a water jacket surrounding the cylinders into an upper portion and a lower portion. Below a predetermined engine speed coolant flows primarily in the upper water jacket portion so as to provide enhanced cooling at the upper portions of the cylinders. Above a predetermined engine speed coolant is introduced into the lower water jacket portion from the upper water jacket portion so as to provide improved cooling of the lower cylinder portions, without compromising cooling of the upper cylinder portions or the conjoined cylinder wall portions. The water jacket insert enhances coolant flow velocity at the siamesed or conjoined portions of the cylinder walls, and directs incoming initially coolant over the exhaust-side of the cylinders. Use of the insert reduces circumferential and axial intra-cylinder temperature deviations as well as inter-cylinder temperature deviations.
