I have a gas/front radiator unit and no, I did not manually downshift. but it creeps up sitting at a light for a minute or so and ran mostly slightly above 210. I suspect rad cap not holding enough pressure or thermostat or fan, what do you think, shouldn't it run at more like 190

Well when sitting and the temps creep up sounds like normal thermostat action. The gauge needle will move up and down in temperature as the thermostat opens and closes while it is maintaining the correct motor temperature. Those gauges are not super accurate but 210* at the high is probably OK. The actual temp is controlled by the thermostat temp setting and they are normally higher these days because of emission requirements. If it was a fan problem then it would continue to climb when sitting still in traffic. The fact that it goes no higher than 210* is a good sign. The radiator cap will not cause that problem. If it has an electric fan then do you hear it turning on and off while sitting in traffic? As far as the temperatures going up when climbing is common if you don't downshift and keep the rpm up in the powerband. Look in your owners manual and see at what RPM your engine is listed for max horsepower then keep it around that RPM when climbing steep grades. So if it is 4400 rpm keep it in the 4200-4400 area by manually downshifting.

In most engines the temp sender is nothing but a high temp senistivity resistor, as the temp increases, as I recall the resistance increases (positive Temp coefficient)

If the wire comes loose, you are now at "infinite" resistance.. or FULL SCALE on the temp meter.. it is called "Fail Safe" that is it fails in the position you find most alarming.

Fuel tanks.. If the wire comes loose.. read EMPTY,, for the same reason.

Of course your question is: Were we REALLY overheated or not?

Check the coolant recovery bottle.. (engine cold) if the level of liquid is normal.. You were not,, Overheat will usually boil off some of the liquid... So if it's still at the "Cold" level. you are good.

It only has 19,000mi. look forward to talkin to or seein' ya one day
I had a 1995 airstream with a 454.It always ran 210 deg. on level ground. I talked to chevy and they said this is the design temp. It runs this hot to reduce emissions. Mine would also go up to as high as 250 deg. on hill climbs. I was told by chevy, that this was normal with this generation engine. Chevy said as long as it did not give a check engine light it was in limits. I drove it seven years and always had these temps but never a problem, so I guess Chevy was right.
