We have a 1988 Astro, and have been running into the same problem. As it turns out, the freeze plugs are being eroded from the inside, and have to be removed and replaced. Out mechanic says he's nervous that the engine block itself may have the same thing happening to it, so he's pretty careful when he changes the things. So far we've only replace the plugs as the problem occurs, and not pulled all of them for replacement.

If it has the 4.3 ltr engine, the intake manifold is notorious for leaking at the back of the engine where you cannot see it. Try using a mirror at the rear of the intake manifold and look for wetness. Replacing the gaskey is the best fix.

A V8 engine is put in a Chevy Astro van by removing the existing engine and removing all unused accessories. The engine can then be put into place, bolted to the transmission, and everything hooked up.
