Abstract
A cooling jacket for an engine has upper and lower bodies. The upper body includes a plurality of upper portions. Each upper portion has a top orifice and a bottom orifice. The lower body is located below the upper body and includes a plurality of lower portions. Each lower portion has a lower orifice aligned with a respective one of the bottom orifices so as to permit a coolant to flow through the lower orifice and into the bottom orifice. The coolant flows from that lower portion to the respective one of the upper portions. Each upper portion has at least one upper passageway extending through that upper portion from the bottom orifice to the top orifice so that the coolant entering the upper passageway of that upper portion flows through the upper portion to the top orifice.
