Having been a mechanic since I was 16, (now 58) I have been amazed at the way people have difficulties in bleeding their cooling systems after work done or changing antifreeze.
Some really extreme tips come up now and again too.
In all my years, I have never ever had a problem bleeding a cooling system and have only ever used one method, after being shown this as an apprentice years ago. Even on modern vehicles, its a proven method.
Here is how I carry this out.

With an empty system, set the heater controls to windscreen, hot, and the fan to 1 or 2. (No faster or you will simply remove warm air and stop heating up}
Start the engine and allow to idle.
SLOWLY add the correct amount of antifreeze.  (Adding slowly stops air being trapped. )
Then SLOWLY add clean water until you reach the correct level.
Leave the cap OFF and allow the engine to reach its normal running temperature and the heater is blowing hot air onto the windscreen.
(You may need to top up as the level goes down when the thermostat opens) so keep an eye on this as if the level drops too much, you may allow air in.

DO NOT BE TEMPTED TO REV THE ENGINE OR YOU WILL CAUSE TRAPPED AIR

Once the heater is hot and the coolant in the expansion bottle is hot and at the correct level, replace the cap to seal the system.
Allow the engine to tick over for another 5 minutes or so to make sure there is no overheating or other problems occuring.
Job done.

Exactly what I do - never had an air lock on mine.

For vehicles with a thermostat positioned in the lower hose, flow to engine from rad, i remove the top hose and filled the engine though it, replace the hose, top up the rad and thats it., never had a problem.... heater control position on a Pajero (mk2) makes no difference to the flow of coolant as the matrix has no flow valves and is always open to the flow of coolant....

Similar Mark, I remove an auxiliary hose the the turbo and fill until it runs out of the housing.
