I would suggest the you elevate the front of car (like on a steep driveway) remove the rad cap, start engine and let it idle for about 30 minutes. Keep an eye on coolant level and add to keep it full. Air will bleed out as the thermostat cycles. The above is an excellent answer. You might also look and see if there are any bleeder valves on this engine. If so use them to bleed the system. Also make sure the heater is set to the high temperature setting to remove air from the heater core.
It's not easy

Air Conditioning Vacuum Pump.
Carefully!!! You will need to pressure bleed the system and it will require a scanner to reset the light.
You're simply going to have to have it removed and replace it. That nipple is at the lowest point in the system and there is no other way to drain it unless you have the system power flushed.

It would be in your best interest to go to bgfindashop.com and have someone in you area do the flush, back flush, for you as they clean the system. Then they do a total fluid exchange to include the heater and then add a rust inhibitor.
The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.
Start with the basics. A complete cooling system service. Drain the coolant, flush the cooling system with the heater control set to hot, replace the thermostat, clean the exterior of the front of the radiator, and bleed all air out of the system. This should correct the problem unless your cooling fans are not working, or you have a blown head gasket. If you are loosing coolant with no apparent leak, exhaust smells sweet, or coolant in the oil, you have a blown head gasket. Failure to repair this will destroy the engine. Make sure you cooling fans are functioning as they should. With the A/C on one fan should run all the time.
Park your car on an inclined surface (15-20o). Start the car and idle it for 5-10 minutes. You can rev it couple times too.
