1899 2001-2007 496 8.1L Chevy GMC water pumpIf you're hauling weight and there is limited airflow your big 496 8. 1L might just start running hot. Flowkooler has a solution. FlowKooler designed a high flow water pump for the 496ci block with a CNC machined billet impeller. It has an increased vane count and a reduced impeller vane clearance to the volute. 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
If you're hauling weight and there is limited airflow your big 496/8.1L might just start running hot. Flowkooler has a solution. FlowKooler designed a high flow water pump for the 496ci block with a CNC machined billet impeller. It has an increased vane count and a reduced impeller vane clearance to the volute. 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 BBC 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. This is particularly true when your truck is hauling weight under a load and there is limited airflow.
From 0-3,300 RPM…Nothing Beats a FlowKooler!

An 8.1L is commonly used in a mercuiser. A customer told us he had a problem installing his but we could not understand what his issue was through his anger. Please do not purchase this pump for a boat; we don't have it in us anymore.
