The 1993-mid 1996 engine is often called the 87gpm pump by the diesel enthusiasts and it was paired with a single by-pass blocking thermostat.  We designed an impeller to outflow the OEM design to help the 6.2L and 6.5L diesel run a little cooler under a load and at slower speed.  Our impeller has a larger diameter, an increased vane count, a more open eye to permit greater flow, a reduced impeller vane clearance to the casting volute and a ported shroud to build pressure in the eye and an appropriate B gap clearance to limit the potential of pressure pulsation or hydraulic shock.

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 Chevy diesel 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.
