Remove radiator cap fill radiator until coolant about to top wait few minutes until coolant level stop dropping then start engine until letr idle,watch coolant level in radiator add more coolant if level drop,when coolant level stop dropping.feel top radiator when top radiator feel kinda hot thermostat opening,coolant will drop a little more add until coolant level stop dropping.when coolant level stop dropping turn off vechicle let it set a while besure coolant overflow full to cold mark.make sure check coolant level when car sel for a while and dont let coolant overflow jug never be empty.keep check make sure coolant level stay full cold mark .if you let coolant overflow stay dry coolant system will pull air in the coolant system cause overheating problems.
No that is not the way on modern engines.

Raise the car front end as high as possible with a floor jack, fill the coolant tank to the top, run the engine until it reaches just short of overheating, shut it down and run water over the radiator, this will burp the air out. Repeat as needed. Don't let the coolant recovery tank run dry during procedure.

if you have 4.7 engine bleed cooling system by fill it with coolant, then install radiator cap and reservoir cap,start engine , rev it up 3000 rpm for ten seconds then turn off ,remove radiator cap and unscrew the bleed plug,then add coolant to the radiator againuntil coolant flows from the bleed hole,then apply film rtv sealant to the threads of the bleed screw tighten securely,then check coolant level add more coolant if low,then install radiator cap,then start engine,let it idle,watch temperature gauge, if engine still trying run hot zone, wait until engine cool so you dont get scalded add more coolant.keep doing this procedure until engine dont run in hot zone meaning air is out the system.wait until engine cool down before adding more coolant, use a large rag to open radiator cap, this will protect from get burn but when engine cool down open radiator cap a little at a time to ease off the pressure,when engine cool down make sure coolant overflow jug has coolant to the full cold level,if you let overflow jug get dry or empty coolant system will draw air in the cooling system cause overheating.
meant to say if engine run in the hot zone turn off engine wait until it cool down then add more coolant to the radiator. depend on engine type all the engine dont bleed same the 4.7 engine bleed different
