    Abstract: An engine assembly and method of distributing coolant in an engine assembly. A cylinder block includes one or more pairs of cylinder block openings disposed therein. Each pair of cylinder block openings include two cylinder block openings, each configured to house a piston. A cylinder head in fluid communication with the one or more pairs of cylinder block openings. A coolant manifold includes coolant flow passages, each in fluid communication with a coolant flow inlet disposed in the cylinder block between the two cylinder block openings in each pair of cylinder block openings. Fluid from each coolant flow inlet diverges into two coolant flow passages, each extending about a peripheral portion of a respective cylinder block opening. Each coolant flow passage extends from the peripheral portion of the respective cylinder block opening into one or more outlets from the engine block and into the cylinder head.
