You need to first make sure that you have enough coolant in the system. To do this just fill the coolant all the way up then start your car and let it warm up, then let it cool all the way down and refill. Do this until it won't take any more. There is a bleed valve on the thermostat housing that you can open to help the air bleed out but usually you don't need to.
