Thank you for the clarification.

Shame on those M6 screws holding the steel flange on being busted off or
whatever , as there is never any reason to remove those two bolts..
that steel flange can just stay where it is, like  forever.
    I have not seen a gasket failure or leak there ever.

Rarely, the steel flange may be corroded ..like with holes in it,
but normally ...just leave it bolted to the housing .

On a 1.9 thermo housing, there are (2) M8 bolts that pass through the housing and thread into the water pump and (4) M6 bolts that are always breaking. Two to hold the above flange on and two that hold the thermostat cover on. I Heli-coil those puppies whenever I had a housing in my hand. Stainless threads and a bit of anti-seize and they never break again.
