      Paul and John,

         Let me expand on this subject. The input I have said to plumb the bottom
 fitting of the expansion tank to input (suction side) of the water pump/radiator
 to keep system pressure seen by the pressure cap to a minimum. The upper expansion
 tank fitting should be small (-3 an hose or not over 3/16" I.D.) and connected
 as John said to the top of the engine block. Its function is to bleed any trapped
 air in the system to the tank. IMHO
