This 9 bolt pump fits engines (with an alternator) built after 1965. 

Flowkooler designed a high flow water pump with a CNC machined billet impeller to increased vane count and a reduced casting-to-impeller vane clearance.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Ford FE 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.

Prior to 1965 Ford FE motors utilized a generator.  In 1965 Ford switched to an alternator.  Please note the 1642E pump has a dowel pin to accommodate the generator bracket whereas 1642 does not.  Additionally the "flat part" of the casting near the hose connection is a greater area which allows for the larger pulley..

From 0-3,300 RPM…Nothing Beats a FlowKooler!
