Flow Kooler High Flow Water Pump 1975-1979 AMC Inline 258

Flow Kooler water pumps solve low-speed heating problems by doubling the water flow rate at low rpm and idle. At 3,500 rpm, the flow rate returns to normal to prevent too much water flow at high speeds. These pumps also last longer than a stock replacement. This inline six cylinder model uses a new 8 blade CNC machined aluminum impeller. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids.  This new impeller has an increased vane count which creates a substantial reduction in the plate-impeller clearance thus achieving greater flow rates, higher head pressure and a more efficient flow than the old Flow Kooler MiraKool design impeller.

 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot 258 engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.
