First when the engine overheats is the clutch fan engaging? Next on
the blocked core it could be that the external part where air flows
through is blocked with dirt or bugs or the fins are badly smashed
blocking airflow. Internally, you might find a shop to flow test it in
car but not too likely. Feel core of raditor (if possible) and see if
it is evenly heating up. I still stand by my 3 suggestions. because
the symptoms match it.

If something was indeed blocked, he would get boiling fluid pouring out
the open radiator cap in the test. He has cool non moving fluid only
with the inside gauge reading above the temp an open thermostat would be
working at.

He could have no real problems with the rad and a wonky sender for the
gauge.

Re: Followup-- 2000 JGC V-8 still overheating
 

Could you be sticking his finger in the wrong area? Had to ask!!
You keep saying 'water' and not 'coolant'.
This is the radiator cap right?

I have known people that add coolant to the engine through the oil cap or
into the washer bottle.

I had to ask since it is hard to believe that your pressure cap allowed you
to take it off safely and the coolant was only warm AFTER you have been
running the engine for awhile getting it up to normal operating temperature.
ODD!!!

You still did not answer my question about the temperature of the radiator
measured at different spots like all four corners!!! You might have an
extended neck on the radiator which might cause that coolant there to not
move around much. Touch the outside of the radiator in the corners AFTER
the engine is at normal operating temperature.

This sounds a little unbelievable to me!!
