I had a similar problem, my fault, drove my '96 XJ across the desert
w/air conditioning and letting the cruise control determine when the engine
should shift... dumb. So it overheated but letting it fast idle in neutral
brought it back to normal within a minute or two. The most common problem
would be a head gasket, with increased pressure to the radiator and/or water
and oil mixing. Absent that (do the compression check), you probably came
out OK... tough engines. Make sure he's with you when you do the checks and
perform maintenance, best learning experience.
Going to watch my daughter change the oil in her '03 4x4 F150 tonight.
Best lessons my kids ever learned.

It never ceases to amaze me how people on usenet take every
opportunity to turn a reasonable discussion into an opportunity to
insult and harangue otheres.

The jeep does not overheat as long as it gets some wind and is not
left to idle in one spot. This is something that my son was informed
of and agreed to. And there is nothing wrong with using an offsized
spare for a short distance, as long as you don't leave the lockers
engaged. Detroit makes cares with teeny spares all the time.

Now that I've patiently given you a much more polite response than you
deserve, get your nose out of my business. It's none of your concern
how I raise my kids.
