1777CCW 1963-1974 Inline 6 CCW Rotation Riser 3 7/8" water pump

If you are running a serpentine belt with a riser set-up and find you have heat cycling it might mean trapped air.  The best solution is to build pressure to and the best tool is pump 1777.  We designed an impeller with an increased vane count and a reduced impeller vane clearance to take build that pressure.  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.  We developed this hi flow pump because trapped air can cause overheating in slow speed situation and stop and go traffic. It has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures.  It has been reported that people who run the heater line to the port between No. 6 and No.8 heads and not the manifold seem to have better luck freeing the air.
