FlowKooler water pumps prevent engine overheating.  Each impeller is designed to generate higher flow rates and increase system pressure. Increasing coolant flow rate through the block reduces the cycle time between the engine and the radiator providing more opportunity for heat exchange. When flow rate is maximized, the higher flow rates raise engine block pressure to prevent the formation of steam pockets in the water jacket and the vapor barrier that can cause hot spots on cylinder walls.
