Steve,
Thanks. You could not have provided a much better illustration. So it is the big hole right below the thermostat. Makes sense as the thermostat closes it off. Fascinating ;-)
Again, I may be creating a problem that does not exist since this is all fretting about stagnant air on an engine that has a load on it on the ground, but I do wish to try to best understand it better.

It is not necessary to remove the water pump housing to verify the thermostat installation. It is accessable by removing just the cover over the thermostat. The photo shows the water pump housing with the cover removed and also shows the stock bypass thermostat
and a non bypass thermostat. The drawing shows changes that can be done to convert to a non bypass thermostat or the non byypass thermostat can then be simply left out.

Yes. I am running a thermostat. Honestly, I am uncertain on which passage to seal off
in order to remove the thermostat. I would hate to choose wrong.
Directions/illustrations here would be appreciated. I must conceded, pulling the
water pump housing is not an appealing thought right now regardless of how good I
have now gotten at such things on the rotary.
I think I may drain the coolant tonight. I will go the distilled with some warer
wetter i think Unless the earth tilts its axis, Houston is not in direct peril from
cold.
