[urq] DO I still use the large round thermostat gasket ifIremovethermostat?

[steven j]

Oh this is gettings scary/complex.  I was the original poster on this.
 
I was thinking with the thermostat out it would make it easier for me to drain and re-fill the system several times, just dealing with the small diameter hose that goes from the resevoir to the bottom rear of the radiator.  I'd always thought that it was having the thermostat closed when the system is filled that results in air pockets and incomplete filling. 
 
I nervous that I'll do more harm than good if I don't completely refill the system.  I made this mistake with an old ford.  Filled it up, drove it around, thermostat opened, let it cool.  Then I found the radiator very empty and  2 more quarts.  The next week  the intake manifold started leaking coolant.
 
I think I've run other cars in the past without the thermostat - but they had one of those flat paper gaskets.  I havent look at this situation carefully but it looks like our round rubber gasket might not stay put without the thermostat.

... I'm pretty sure the t-stat switches the flow from an internal cycle
to one that includes the radiator. What happens if all the passages are
opened? That's the question I'm posing. Can it create a situation
where the pump is not able to send fluid anywhere?
