COOLANT FLOW

The coolant is circulated by an impeller type pump mounted on the right-hand crankcase and driven by a gear. The coolant is drawn by the pump from the bottom tank of the radiator, through the pipe 1, and discharged into the cylinder head and cylinder through the pipe 2. The coolant passes from the cylinder head through coolant ways and after circulating around combustion chamber jacketing enters the radiator upper tank via inlet pipe 3. The heated coolant from the engine then passes down through the finned tubes to the bottom tank of the radiator. These finned tubes present a large surface area to the air and dissipate the heat.
