as state din other threads take off the rad cap start the car let the fan cycle on a ferw times. this will release the air bubbles out. put back on the rad cap and you should be fine. you could also start the car and loosen the weep hole bolt by the thermostat area and have it like that til there is a steady steam of water coming out which indicates no air bubbles. re-tighten the bolt and you shoul be fine.
