  • 1520 1983-1986 Land Rover Range Rover 3.5L water pump
    Quick shop

    Flowkooler High Flow pump for the Range Rover 3.5L motor 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 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!

    General Specifications:
    Type of Material of Pump Body Aluminum
    Number of Blades on Impeller 16
    Direction of Rotation CW

    If you own a Land Rover with a 3.9L, 4.0L, 4.2L or 4.6L engine then you have probably have heard all of the reasons they overheat. Some blame the steel liners shifting within the aluminum block.  Some blame combustion gases in the the coolant and/or the crankcase system.  Others point to micro-cracks in the block, porosity in the block and a myriad of other reasons.  One customer called us to say that he noticed the temperature rising at a low idle and he discovered our pumps as a possible solution.  Unfortunately we did not have an impeller for this pump but he has convinced us to develop a hi flow impeller to increase the coolant flow rates to help mitigate the temperatures. 

    This pump will be coming soon - email us to be placed on a list.

    Flowkooler High Flow pump for the 1964-1970 Buick Jeep and Olds motors has a CNC machined billet impellers that are designed with an increased vane count and a reduced plate-to-impeller clearance.  This design achieves 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 due to the higher pressures, we re-designed the plug and now machine a 6061 billet aluminum into a press fit plug that will never come out.

      Flowkooler high flow pump 1618 for Buicks with 455ci motor has a CNC machined billet impeller designed with an increased vane count and a reduced 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 Pontiac 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.

      Flowkooler designed a high flow water pump with a CNC machined billet impeller.  With an increased vane count and a reduced casting-to-impeller vane 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 Ford 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!
