burping a 2.2 head

[MIKE_MN]

I KNOW THIS IS THE WRONG FORUM.BUT I AM SURE ALL THE WRENCHHEADS ON THIS BOARD WORK ON OTHER TRUCKS. I AM REPLACING A CRACKED 2.2 HEAD AND WAS TOLD TO BURP THE HEAD(REMOVE ALL THE AIR(REPLACE WITH ANTIFREEZE) FROM THE HEAD. DO I JUST FILL UP THE RADIATOR OR DO I HAVE TO DO SOMETHING SPECIAL.
I KNOW STEVE CHIN WILL PUT IN A GOOD SUGGESTION. SO THANKS IN ADVANCE. THANKS FOR THE HELP EVERYONE.

air usually gets traped below the thermostat. you can fill the radiator up and wait till the water slowly fills the gallaries in the block/heads/etc or remove the water thermostat housing, fill to the rim and replace it. check the water level in the rad once your engine is warm(thermostat open).

It also helps to agitate the cooling system by repeatedly squeezing the hoses. I like to jack the car or truck up so that the radiator is also located higher than the engine to help any air pockets leave. A lot of guys will drill a couple of 1/8"-3/16" holes in their thermostats to aid in air escaping.
