I have to bleed the air out of the 280 SE by opening one heater hose at the heater core, it won't push the air out under water pump pressure, and the heater cover gets airlocked -- no heat.
Ah! So the manual authors did know what they were doing! Makes perfect sense. Thanks, Peter.
But, correct me if I'm wrong, goosing the aux pump to force turnover of the heater core contents is something that should happen after coolant is already in the block, nicht?
So it turns out there *already* is coolant in the block, to my surprise. See my separate post in Tech Help about "teleporting coolant".
