1776p 1975-1985 Buick Chevy GM Olds Pontiac 5 9/16" short polished water pump

Flowkooler high flow pump 1776p has a polished aluminum casting with CNC machined billet impeller designed with an increased vane count and a reduced plate-to-impeller 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 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!
