1669 1996-2006 LS Motor water pump

$249.00

Flowkooler High Flow pump for the LS motor has a CNC machined billet impellers are designed with an increased vane count and a reduced plate-to-impeller clearance to achieve greater flow rates, higher head pressure and a more efficient flow than other OEM water pumps. The color is due to Type II Class II military grade anodize surface coating which protects against corrosive fluids. 

The pump originally had a die stamped plug plate like the OE but our earlier design created pressures that blew the back plate out.  We re-designed the plug and now machine a 6061 billet aluminum into a press fit plug that will never come out.

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