If your Ford 7.3L Diesel is running hot Flowkooler has a solution.  FlowKooler designed a high flow water pump for this block with a CNC machined billet impeller.  It has an increased vane count and a reduced 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  when towing or under a load? 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.

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