I'm going to be doing some major work on the front of my 93 Aerostar's
engine compartment soon.....changing the A/C compressor, radiator
hoses, belts, etc. The van runs great at 173,000 miles and I plan on
keeping it for quite a while as a second vehicle. Just wondering how
long timing chains usually last in that engine, and whether it would
make sense to replace it while I'm "in the area".

Wondering the same thing about the AutoZone rebuilt water pump I had
to install while on a trip across country about 20,000 miles ago. It
only had a 12,000 mile warranty, but is still working fine. I got
145,000 miles out of the original water pump. Are the rebuilt ones
usually good for 100K or so?

If you've never had the timing chain done before it's time to replace
it.

IMO I'd put another water pump on especially if it came from AZ. A1
rebuilt water pumps carry a 3 yr/36000 warranty (at least that's what
we honer at my work). Also check into getting a new one, they might
not be that much more, and usually carry about the same warranty.

If somebody asks me about a timing chain, I tell them to just run it
until it fails.
But in your case, especially if the radiator is being replaced, you
may as well replace it. All you've got left to do is pull the dampner
and the timing cover.
Same with your water pump, even if it hasn't failed. Most
manufacturers and rebuilders use the cheapest bearings they can
contract.
It's cheaper to do it now instead of having it leave you set somewhere
on the road.

I had to replace a pump on my Dodge van a few years ago under
similar circumstances. The Autozone rebuilt didnt last very long.
When I pulled it apart, it was corroded, bearing was out. I replaced
it with a new Autozone pump (again, because of accessibility) and
it worked fine.

Autozone does supply new parts, and I dont really recommend their
rebuilts except in necessity
