SOURCE: cooling system
usually the thermostat will have a little hole in it to help the air out of the system. so let it sit for a few minutes and check the water fill it again leaving it just a little bit low. then run the engine with the cap off untill you see the water circulating through the thermostat. shut it off fill the radiator and your done.

SOURCE: How do you bleed the air out of the coolant system
it should bleed itself ,start up let it warm up then check level when its cold ,use only 50% antifreeze ,better still neat

Old methos id to leave the raditor cap off and squeeze the coolant hoses to get the air out.
SOURCE: how do you bleed the air out of the coolant system
The generic method of bleeding air from the cooling system of any car or truck is to use a floor jack and raise the front of the car as high as poss, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the cooling systeml , if it still overheats then you need to have the head gaskets checked with a gas analyzer for hydrocarbons present in the radiator or recovery tank
