Put the cap on the radiator
Fill the resivior to the max line, maybe a little more.
Go drive it, do a full throttle accel and wind the engine up all the way.
Check the resivior that it is still at filled to the max line. IF it dropped you burped an air bubble. Keep repeating until it stays at the max line. Your air bubbles should be all gone at this point.
Do NOT remove the cap on the radiator any more. This WILL introduce mor air into the cooling system. Only add to the resivior.
the resivior is part of the pressurized cooling system so don't remove the cap while the engine is hot.
Technically the resivior is not an overflow tank like cars of the past. It is part of the pressurized cooling system and is really a "degas bottle", who's job it is to remove air bubbles from the cooling loop. Also happens to act as an expansion chamber. If it gets low then it can't degas the cooling loop. Keep it filled to the max line and it works good.
High engine RPM spins the water pump the fastest, which pumps the hardest, which will help push out the air bubbles. You will never push out air bubbles if it just idles, needs RPM.
Was I the only one who was sobor and paying attention in college?
