There is a bleeder screw (it looks similar to the type you would see on a brake caliper) on top of the thermostat housing. This is on the passenger's side of the engine, right where the large radiator hose goes towards the firewall from the radiator. Opening this bleeder screw (ONLY WHEN THE ENGINE IS COLD) will allow trapped air to escape. Be sure to keep the coolant tank at the "cold full" mark while doing this. If the coolant tank runs dry, you likely will introduce more air into the system.
This is often caused by air being trapped in the cooling system. Get a qualified mechanic to drain, flush and refill the radiator/cooling system.
You have air trapped in the cooling system that needs purged out of the system.
Round.
It is a brass fitting on the top of the thermostat housing.
Engine cooling system is not a closed system you can't remove the air.
It doesn't have one.

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)
You may have air pockets trap in the cooling system.
COOLING SYSTEM OF WHAT ??????????????????????? Most auto parts stores sell cooling flushing kits. Get one follow the directions and it should take the air out of the system. You must remember that your heater is part of the cooling system as well as the cooling for your transmission.

If the cooling system is in good working order the system will bleed the air out itself. If the system has a leak anywhere no matter how small the system will never bleed the air out.
