If you mean "purge" the air out of the cooling system, then loosen the top radiator hose at the radiator. Pour coolant mixture into the hose until most of the air is purged and replace.
To bleed air from the cooling system, take off the radiator cap and let the engine run. IF there is no radiator cap(some vehicle manufacturers have done away with them, just add coolant to the overflow tank to the correct level. The cooling system will purge air out on it's own
there should be a little purge valve located on the thermostat housing just crack it open and start your engine and you see antifreeze start to come let it flow for about 30 seconds then close it. That should purge out the air.
park your car on a steep hill and let run until you see or hear all the air bubbles come out

I assume you are talking about removing trapped air from the cooling system. Park uphill or jack up the front of the vehicle. Remove the radiator cap, turn heater control to hot, and start the engine. Keep the coolant level full, while the engine runs. Watch for air bubbles escaping from the radiator. When you see none, all the air is purged. It may also have a Schroeder valve somewhere on the cooling system at the highest point that can be used to purge air.
Engine cooling system is not a closed system you can't remove the air.
Have you done a rebuild? Is this why your trying to purge the cooling system? Typically you will need to run the vehicle till the temp gauges reads near overheating, then allow the vehicle to nearly cool and remove the radiator cap. This allows air pockets to be pushed through the system. You can also run it to normal operating temperature and slowly crack the radiator cap allowing the system to expell excess pressure.

Air bound means that there is an "air bubble" in the cooling system that is preventing coolant from circulating in the cooling/heating system. (air can be compressed fluid cannot)
This should happen automatically. Are you losing coolant, is the cooling system leaking somewhere? Have you just changed the coolant? Unless there is a leak, the system should purge by itself.
You may have air pockets trap in the cooling system.
