It could have been so sloppy that the last alignment
could only do so much or was with the slop so far away
from the correct setting that when you fixed it the
rebuilt item repositioned your steering correctly but
rendered the old setting inaccurate?  

Check the other links in the steering for slop and
correct before doing another alignment.  Do the
alignment then and you should be good to go.  Same
thing happened to me, by the way.  Rebuilt it, aligned
it, and no problems since.

Probably not intentionally screwed.  Has the patient
been back to the radiator shop that did the work?  

Those guys tend to be pretty smart about diagnosis and
trouble shooting.

"Maybe?" a bad thermostat?  You can take yours out,
put it in a pan of water on the stove and heat the
water.  Watch the thermostat periodically and see if
it opens fully.  If not, then there you go?

Did the hoses installed have metal wire in a coil
inside?  Are they collapsing under heat (especially
the lower?  This could strangle the water flow as the
pump sucks water, the lower hose collapses once warm
if not internally braced with a spiral metal wire. 
Look at the lower hose when the car is warm.  Still
tubular?

Maybe a bad gauge (unlikely).  Have you taken the
car's temp and compared it to what the book says it
should be when warm?  I didn't do this myself - I like
asking others that have been around, but if you're out
there all alone too far from the radiator shop and
all...

Try running the car without the thermostat to see what
affect that has?

Is your fan belt tight and spinning the water pump
correctly?  Is water flowing through the radiator? 
Leave the cap off and warm the car up.  when cold, the
water won't flow as the thermostat is closed.  If
there is hot air from the heater, then it's open and
flowing.

Heater is a good way to shed a little extra heat if
the car is running warm and you want to attempt a limp
to a service place by the way...

if you did all the other stuff, then is is either a
bad component, bad work, or a victim of cosmic
radiation or the radon in your house.

You'll likely have to start swapping parts out to try
to isolate the problem.  I'd suspect the radiator,
myself.  

It's also theoretically possible that your engine is
so filled with scale that it isn't getting good
circulation, but I'm not real big on that theory
myself, having never experienced it firsthand or known
anyone else who has (radiator shop guys might know
more about the general likelyhood, as they'd probably
get blamed and have to uncover such a condition to
exonerate themselves...)

Maybe someone else on the IML will speak up with an
alternate idea?  Hope so!

Write me off-list of you want a fan shroud for your
car - I think I have one somewhere.
