A cooling system for conversion of air cooled aircraft engines to liquid cooling, including replacement cylinders, light weight, flex tolerant coolant manifolds and cooling system instrumentation for monitoring coolant temperature and pressure. The replacement cylinders have internal gating of coolant flow between a cylinder jacket and cylinder head exhaust port cooling passages for continuous high power operation of the engine.

1. A replacement cylinder for use in providing liquid cooling to an air cooled internal combustion engine of the type having one or more piston cylinders exterior to a crankcase block, said replacement cylinder comprising:a unitary casting including a cylinder head portion, intake and exhaust ports and spark plug openings in said head portion; said cylinder head having coolant passages therein; and a double walled jacket defining an annular coolant cavity having an open end and an opposite end closed by a head portion having intake and exhaust ports, said head portion including coolant passages in fluidic communication with said annular coolant cavity, a coolant inlet and a coolant outlet on said jacket for circulating coolant through said coolant cavity and said coolant passages; a flow gate near said coolant inlet for diverting a substantial portion of coolant flow from said inlet into said coolant passages and the balance of the coolant flow into said coolant cavity; and a cylinder sleeve fitted to said open end of said double walled jacket of said unitary casting.
