What happens when engine overheats?
Not having learned from the last time, I let my teenager take the jeep
out for the weekend. I warned him that it has been overheating and
not to push it too hard, but he didn't listen... and now I have found
out that not once, not twice, but three different times, he let the
engine completely overheat, then just waited for it to cool off,
restarted, and drove on.
There doesn't APPEAR to be any lasting damage, at least not on the
surface. But I'm wondering what may lurk in store. What happens when
an engine overheats? what components are most likely to be damaged
and in need of attention?
(In case you are wondering what happened last time: He had only a 32
inch spare along with a jeep that otherwise ran 36 inch tires. He put
the 32 on when he got a flat, and then drove home. This in and of
itself might not have been such a disaster, except that he left the
lockers engaged and drove home 70 miles on paved roads.)

This will teach you to let a youngster have a vehicle that is not in good
repair!

Depends on the severity of the overheat.
You will see nothing till the damage makes itself known.
At any rate, it's time to change the oil since it's gotten way
too hot for its own good.
Take the oil out of juniors allowance. Having to spend $ on something
that isn't fun has a way of making kids pay attention.

Amazing the smaller tire still has rubber or the locker didn't grenade.
Sounds like junior needs to be restricted to having an adult with him/her
at all times when driving.

I disagree. Just don't give the little fellow broken cars to play with.
Known tendency to overheat = broken. Wrong sized spare = broken. About the
lockers though. I would give him a lecture about that, and an explanation
that they are "off road only" equipment.

Re: What happens when engine overheats?
as far as i know it can cause the head gasket to crack and the engine head
to warp-especially on the long 6-cylinder heads we have in the 4.2 and 4.0l
engines. excessive heat also causes the oil to breakdown faster, decreasing
its usefulness as a lubricant. i'd give the kid a stern talk about
responsability....

Re: What happens when engine overheats?
Why was it overheating in the first place?
Overheating can cause some nasty damage.
The valve seals for one bake hard and then you start having blue puffs
of smoke when you first start it up in the mornings and it will forever
burn oil until fixed.
The head gaskets on the 4.2 engine for one will usually let go. This
can mean exhaust in the rad or oil or coolant going into the oil or
cylinders. Watch for a white puff of smoke when starting, that could
mean coolant inside the pistons.
I would be doing a compression test to check the head gasket. This
doesn't always identify every way a head gasket 'can' blow, but it can
give you a good indication if one or two cylinders, especially side by
side or end ones have low compression. For some reason I have seen the
most problems with the head gasket on #6 or between #3 and 4 after an
overheat.
If the valve seals or head gasket is blown, then having the head rebuilt
and shaved flat is called for. The valve guides can wear extremely fast
with no coolant too.
Good luck.

Re: What happens when engine overheats?
I would expect huge drivetrain issues if he drove with 1 odd-sized tire in
4WD... especially that big a difference. I know Subaru (AWD) says that if
you replace 1 tirem replace them all or you will fry something. I had a
mechanic show me the results of a guy buying 2 new tires and putting them up
front... old tires in the back (50% wear?). Not a pretty picture.
