Lets look at the probablity of air pockets. I think you have a stubborn one. Raise the front of the van up 3+ feet or as high as you can get it. Add coolant a few ounces at a time. Keep reving up engine, lettling it come back to idle. May take 50 times of this slow procedure.
There is a tool that snap on makes. Prolly others too that attaches to the rad and puts a vacuum on the system to pull the air out. The aerostar can be a real stubborn one to bleed. The engineers didn't worry about that when they built it. I'm pretty confident that you'll nail this thing if you get the air out.
