>with the engine on the wrong end also.
Paul, lets get this settled. We have our engine on the "Wright" end. This
way we have a clear view of the world.

The input I got about the expansion tank was to plumb the lower connection
down to the radiator and the upper connection to the top of the block.
That's what I did, and apart from the problems I had with the thermostat, it
seems to work fine. I have a 23 lb cap on the expansion tank and a small
overflow bottle. I'll be interested to read answers to your question about
doing without the plastic bottle.

Regards,
john

     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
