The hole to plug (if not using a RX-7 Maza thermostat) is
the approx 1/2" dia hole right below the thermostat - don't plug the largest
hole (that is the pump outlet hole). I tapped the 1/2" hole and screwed in
an large aluminum Hex plug).

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
