I have flushed the radiator and engine and want to know if there are any special instructions I need to know. As an example: is there a bleeder valve to assure I get all air out of the system? If you know of any special instructions, I would like to hear of them.

You got lucky and the astro is one of the easiest to bleed. Just fill rad to the top and then start engine with the cap off and slowly add coolant for about one minute then put the cap on and refill the overflow jug. Thats it.
