1775 1971-1990 Buick Cadillac Chevy GM Olds Pontiac 6" tall water pump for AC cars

DO NOT MIS-ORDER - ALWAYS CHECK THE PUMP HEIGHT Flowkooler high flow pump 1775 for the 455ci motor has a CNC machined billet impeller designed with an increased vane count and a reduced casting-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 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!
