I'm not sure I'm exactly following you. My impression is that the step where one
adds coolant with the engine cold and not running, such that a steady stream of
coolant comes out the bleed valve, does *not* ensure all air is out of the
system. Just a good deal of it. For one thing, liquids hold entrained gases
better when cold. For another, without the engine and so water pump running, air
bubbles will tend to stay lodged in high spots.

It's the subsequent heating of the coolant while running the engine and with the
radiator cap loose that gets the last bit of air out. At least, that's my take.

When I last did a bleed, I certainly saw air bubbles at the filler neck of the
radiator when I ran the engine. Made sense to me. Sort of the final purge of the
last bit of air.

BTW, how long did it take for your radiator fan to come on, and what was the
ambient temperature as you did this?

Glad to have the update. Good for the archives! :-)
