If your pressure cap equipped expansion "reservoir " coolant
level is higher than the rest of the system with about half a liter of air
above the coolant the system will self bleed & need no external
bleeding. (one thing the highest part of the engine coolant passage should
have a line to the tank. This as worked on vehicle that I worked on
since 1964 until I decided to semi-retire in 2000!.

Re: Coolant Leak
Add a little accumulator somewhere near the high point in the system.
A
cup would seem to be more than adequate. Aside from that, maintain
your
efforts to purge all air from the system (you CAN'T purge it form
the
accumulator.
Of course that *does* involve another footprint somewhere ... Jim
