Jake,

In other words, you clamp a length of pipe onto the coolant reservoir to
raise the level over the radiator, then fill 'er up. Sounds easy, as you
say. The air just bubbles back out?

Funny, I've never had any need to bleed the system, even after doing coolant
flushes, changing water pumps, etc. It just seems like you fill it up, drive
it around a bit, put more in if necessary, and that's it. Is there something
I'm missing?
