Is the best way to bleed the air from the cooling system on an M119 (E-class 124) to fill through the upper radiator hose as it's disconnected at the radiator or ????

I completely drained the radiator, and both engine drains when I had the evaporator/ heater core out, but the system only took about 10 quarts total to refill. Shouldn't it have been closer to 16? Seems to run hotter than before.

Thanks for any help.
