The system is easy to bleed
Engine off, heat left on beforehand
Reservoir cap off
Fill with coolant
Clean the overflow hose end
Put a wrench on the bleeder, hold this in your left hand
Put the overflow hose in your mouth (do not suck!)
Put your right palm over the filler neck
Blow into the overflow hose, pressurizing the coolant reservoir
Open the bleeder, then close, then stop blowing
Inhale though your nose
Repeat until the system is free of bubbles. You can give it one more bleed later when hot and running if you like.

This method works great as long as you do not somehow drink a bunch of coolant, which is poison. So don't.
