Basically run the car and let it warm up. Open the bleeder screw located on what looks like a metal bar running horizontally under ur hood, u will see a little screw and there will be a sign that says "caution do not bleed when hot" or something. With it warm and running preferably, open the screw just slightly at time, if nothing happens that means there is air coming out, leave the screw open until coolant starts flowing out. Turn off car and back on and repeat process to insure all air is gone.
