I have a 97 Aurora just changed the thermostat, radiator, and I am still running warm when I idle in traffic when I'm on the freeway its perfect temp should I be worried or is pretty normal this is my first gm car and Aurora it only has 100,600k miles

Since your post is unpunctuated and contains at least 5 sentences, maybe 6, I can't be positive of the meaning of your question so I'm not answering, in case I say something completely unrelated to your actual subject and look like a dufus. I'd hate to look like a dufus on the Internet......
And over 100 million miles?!?!?!?!? Dayum!

What does the gauge read? I think its pretty normal to get a tick above 200 idling, especially on a hot day. The fans on these cars don't turn on until it gets VERY warm (unless you have your PCM tuned to have them come on at 205° like me  ) |

It will sometimes jump to the notch right above 200 but it stays steady, i just wondered because all the other cars i own they just stay steady, the temperature gage never moves, this one just makes me nervous, i dont want to blow the head gaskets, and for the record the milage is 100,604

My 96 I've had for about 4 years has always hit that line above 200 ONLY when exiting the expressway and going into stop and go traffic, and stop and go / slow traffic in the summertime in general. (I drove an Olds Trofeo with a 3800 V6 for about 18 years, before the Aurora, and it behaved exactly the same way.)
I don't remember what that temp is digitally, but it wasn't as scary as I thought (but that's my opinion.)
Next time I have my OBDII device plugged in the diagnostic port, I'll post what those temps are...

My rora only heats up when its hot outside/stop and go traffic. Ive taken a few 60 mile freeway trips and it runs at 180

Then when you come off the freeway and sit in traffic, it goes up a bit? Perfectly normal.
While the car is moving, you have gobs of air through the radiator. When you're in traffic, you don't. Temp goes up and the fan kicks on, stopping the temp increase, and dropping the temp enough to turn the fan off. What those fan threshholds are I couldn't tell you, but that's completely normal. Without airflow there's less cooling, and the fan forces some airflow. It can't force as much as moving through the air at 60, though!
Your situation sounds completely normal. Temps going up (but still under control by the fan) is NOT overheating. Temps going to where the warning lights come on, and steam blows out from under the hood is overheating.

Main thing I'd suggest is turn on the a/c and make sure both fans are running.

My first notch above 200 is about 220. Higher than I would like but not out of specs.

When I come off the freeway its fine, and when I turn the ac on none of my fans come on which makes me think something is wrong with my fans. I called Oldsmobile today and they said the fans will only come on at 229°. I drove it today and only went over 200 a little bit, so I'm kinda at a loss

Yep that sounds about right as far as the temp the fans turn on, can't remember the specific temp but it was around there. IIRC they should come on with the A/C on max though.

Would it make any difference if I told you the ac don't even work in that car the compressor is messes up

If your AC doesn't work then unplug the coolant level sensor at the reservoir. This should put both fans in low speed. If not you have an issue with the cooling fan circuit. Your temps seem fine though. The next hash up from 200* is 220*.   |

200 to 220 is nothing. Don't compare it to "boiling at 212" because the system is a) pressurized, which raises the boiling point, and b) not just water, but water and anti-freeze, which has a significantly higher boiling point.

I've also had the same worry's about my 99 my friend and the only thing you can really do to know for sure is to drive it till you hit 200 let it idle till it reaches 229 and open the hood and wait to the fans kick in if they don't or they do and the temp still rises then you have something to worry about but as wfooshee has said to me these cars are made to run this way...nothing's wrong just drive it broths.....that is unless that som ***** really does overheat...then you fix that som *****. peace
