[Healeys] Closed system- little confused

[Jeff Pelletier]

 Ok... im going with the closed radiator system you guys have talked
about in earlier post..  but im a bit confused as to how the
water/antifreeze gets BACK into the radiator..  We put a gasket ontop of
the radiator just below the cap to seal things off--correct.. ...  then
you have the inlet/outlet hose/pipe.. then at the bottom of the neck you
have another gasket with the pressure of the  spring on it...  as the
car cools how is the water going to get past the gasket at the bottom of
the neck back into the radiator??



Thanks
