Purging air from radiator
After posting on the Heater core issue from below I was just thinking about something that has always been a bit of a PIA for me. What is the correct and recommended way of removing air pockets from the cooling system in an Aerostar?
I have had van on an incline, flat, squeezed hoses, blipped the throttle, everything. I always seem to have air in there.
What is your preferred method? I am sure there are many different answers.

On my 79 bronco I have allways had air trouble. I have found that switching heater core hoses has worked the beast. of course this is mostly for air in the heater core. I have not looked at the heater hoses on my areostar to see how dificault this would be, or if they are the same size, but may be worth a try.
Make sure the presure cap is ok and not to high. I think 13 lbs sounds fermilure. If it is to high it wont let the air "burp" out.
Also make sure the return hose is clear, and atached.

On my 92 3.0L after replacing the water pump I had an apparent air pocket in the main heater core that I just couldn't seem to purge. I tried each of the options you indicate (running heater with van on incline, etc.) to no avail. Decided to live with it as the rear heater worked fine. Then after taking a 250 mile trip to San Antonio where I drove up and down hills constantly, the system finally purged itself and the front heater now works super.
