1776 1971-1985 Buick Chevy GM Olds Pontiac 5 9/16" short water pump for Non AC

DO NOT MIS-ORDER - ALWAYS CHECK THE PUMP HEIGHT Flowkooler high flow pump 1776 has a 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 Buick or Olds 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!
