1681 1963-1977 Small Block Ford Mercury 5-9/16" CW passenger side intake water pump

$141.78

Small block Ford running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller for the CW rotation.  It has an increased vane count and a reduced casting-to-impeller vane clearance to achieve 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 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.

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