If it has bleeder valves then use them to bleed the system, if not, jack up the front of the vehicle as high as possible. Remove the radiator cap and start the engine. Add coolant to keep the system full. This will allow air to escape.

Not necessary on this vehicle.
As you did not include engine or Year info I will give a general answer. Look on the top of the engine, most GM products with a bleed system have a small brass pipe thread plug in the top of a black or aluminum casting. This is the bleed point, loosen the plug or valve and add coolant to the system until it flows from the bleed, tighten up the bleed. Done. Repeat if needed.
