Hello again, Air can be a real challenge, Elevate the nose of the car so the radiator cap is at the highest point. Let it run, and try squeezing the upper radiator hose, keep the radiator cap off. Let it run until you get heat or the cooling fan comes on. At that point, the bulk of the air should be out. Just get that radiator cap location higher than the rest of the engine, that will help the air travel upward.
I just clecked, look for a bleeder on the rear thermostat housing. I'm going to post the official procedure, See if that helps
