Over time the system will pump out the air. Fill as best you can. I used a clear tube to the tank. You can see plugs of air and coolant move in the tube. As the air plug is forced into the tank it will bubble up. Upon the radiator cooling, coolant will be sucked from the tank into the radiator. Over time all air will be purged. This will work even if the tank is below the radiator neck. A really good spot is below the battery in the fender area. As long as the tube is submerged in the tank and air tight at the radiator neck it works very well.
