Or just plain a bad one.... That happens. I think yours must be
opening 'some' or you would get a boil over.

I fully disagree here. He can keep chasing monkeys but I am pretty
sure it is one of three problems. THe first that the core is blocked
externally with dirt and bugs limiting air flow through it. The second
is the clutch fan is bad because contray to popular belief ram air
will not always cool engine especaily when a big V8 is packed in a
small compartment. Some seem to think that they never good bad but the
thermostatic coil on them ages and when it does it retards the
operation of the fan. (I have posted instruction on how to adjust the
clutch fan in my forum) When it is 220 or so the fan should be a
humping. The thrid is the core is blocked internally which can happen
if proper coolant quality is not maintained. I would check it in that
order or you can just keep chasing the monkey around and never catch
it.

Re: Re: Followup-- 2000 JGC V-8 still overheating
SnoMan, I had the fan clutch replaced about four months ago. Yes, I know
it could be defective, but talk about chasing monkeys, I am not quite ready
to put another clutch in. You posted a very good article on adjusting the
fan, but my mechanic indicates that for the labor involved, he would only go
with another new fan. I am not ready for it, as I see that as doubtful.
When you say the "core" could be blocked, exactly what part do you mean ?
Are you speaking of the radioator itself ? I am thinking more and more
that it is the radiator. Perhaps you mean the radiator core, huh?
Can a flow test be done without removing the radiator?

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.
