*Before installing the water pump, grasp the impeller with one hand and the drive hub with the other and twist to make sure the impeller is tight on the drive shaft. Not finding this problem beforehand can make you crazy.

*Although it may not be necessary, the concept of a "water pump conversion disc" is intriguing. Flow Kooler originally marketed flat aluminum discs to rivet to the backside of the stamped steel impeller in the pump. With an iron impeller, a steel disc could be welded or brazed onto the impeller. The disc wouldn't be that difficult to fab up yourself. Space the water pump backing plate back farther with a couple of gaskets to prevent interference of the rivet heads on the backing plate if riveting a disc to a stamped steel impeller.

This disc should make an appreciable difference in the flow of water at engine speeds under 3,000 RPMs.  On the other hand, Howard Stewart of Stewart Components (the guy with the water pump dyno), says that the disc's have little to no effect.

NOTE: Viscous fan couplings can be a fruitful source of overheating.  Sometimes these will appear to be stiff when cold but they will free-wheel when hot!  As the units have such a brief lifespan the writer likes to scrap these units and fit a solid fan (a differently pitched fan will be needed)  For the best cooling an electric fan ''blowing'' into the radiator is a good arrangement.
