How do you know it's overheating? Does the service dummy light come on?
It could just be a bad gauge or sending unit. Got a buddy with a scanner?
Been a while since I screwed with a 4.3. I think there's a sending unit
on the intake manifold and another on the driver's side head between two
spark plugs. One or the other might be called a switch, that feeds the
computer that controls the fan clutch.
Very well could be crudded up radiator. One of the reasons you're
supposed to use 50/50 anti-freeze and distilled water, not water out of
the garden hose.

The radiator fan is not electric?
If it runs off a belt then fan speed is tied to RPM; same problem only
different.

Not electric ...

S10 would have an electric radiator fan. If it gets hot when you
stop, could be a weak fan motor.
I had a Cavalier, same engine as S10. It sometimes just ran hot,
but hot at 42N lattitude might be very different from 'hot' in El
Paso....so maybe nothing is "wrong".

My wife bought a 2001 4x4 Chevy S10 Vortec 4.3 from sons wife.
We knew it heated up a little...I replaced water pump, fan
clutch, thermostat, had system flushed including heater core
along with radiator. It doesn't heat up us as much...you can
run it on freeway with temp at 210 degrees...once you exit and
stop, it gets hot for a bit then cools off again. No detectable
leaks, no water in oil...wonder if sensor if faulty...any ideas
or tips...we want 4x4 for winter hiking season. Thanks
