Temps
Has anyone ever tracked the temperatures for what might be average running numbers when the car is running well?
It was 101 according to my HVAC readout and the coolant was 217, the engine oil was 207 and the auto trans was 206 and the car was running pretty well.
Just curious as to how those stack up against anyone elses? I like to make notes of things like this so when something does go wrong, I have a baseline to work from which I might consider normal.
Its the automotive "geek" mechanic in me.

Mine in stop and go traffic 90+ degrees with the air on (which keeps the fans running) generally will show me anywhere from 210 to 225, I have even seen 230 briefly at one time but I can clearly see when the second fan kicks on as the temp starts to drop, then once traffic gets moving and air starts moving through the radiator I see 198 to 200 all with a stock thermostat. On a trip over labor day at 85-90 degrees at 70 to 75 mph I never saw much more than 198 and most of the trip while running was 194.
Again, post how you were running at the time and the guys here can give you a good feel for what they see under the same contitions.

Sorry slider...darn good point!
It was a trip comprised of 13 miles of start and stop followed by 56 miles on the interestate then 3 miles of start and stop again. Stop for around two hours then repeat the trip in the reverse direction.
Temps taken at the end of each leg of the trip and they only differed by around + or - 5 degrees.

Here's something I posted not long ago on a short run I had made: 
Your temps seem within range.

Two weeks ago I made a 1300 mile weekend road trip from Oklahoma to Denver. I drove a constant 75 mph for 9.5 hours going up and 9.5 hours coming back. Only stopping for fuel and meals. The air temp was no more than 80 degrees. The car coolant temp never got above 196 and the transmission temp never got above 183. Fuel mileage was 28.1 average for the whole trip. Now, in stop and go driving in traffic coolant will rise to 215-225 on a hot 100+ day.

my 04 usually runs water temp at 192 with the air on and the cruise set at 78mph regardless of the run. (yes that is with temps in south florida breaking records recently). my hemi magnum just ran 4+ hours air blowing on the fl turnpike 78mph cruise on and the water temp (normal operating temp) was 232. the magnum runs that temp (air is almost always blowing) regardless of turnpike or city driving.
the vette will run at about 218 with the air on in the city or stop and go on I 95. the vette is n 04 CE convert 6 speed.
on the really warm evenings, no air, top down, it isn't unusual to reach the electric fan limit and have it kick on (230 or so) to cool thing back down if i get caught in less than free flowing traffic.

I run at about 225-232 in 100 degree weather stop and go and about 195 on the highway. Cars are designed to run hot from the factory and this is from the service manual before I here another noob say that's to hot.
From the service manual
C5 Cooling Fans Operation
The low speed cooling fan is commanded on when the coolant temperature reaches 108°C (226°F). It is turned off if the coolant temperature lowers to 104°C (219°F). The high speed cooling fan is commanded on when the coolant temperature reaches 113°C (235°F). It is turned off if the coolant temperature lowers to 108°C (226°F). When the A/C is on and the coolant temperature reaches 85°C (185°F), the low speed cooling fan will be turned on at vehicle speeds less than 56 kPh (35 mph).

I was concerned about my temps as well when I got my c5. I thought a near 40 degree operating temp was way out of bounds from highway speeds to stop and go. I've learned these cars run on the hot side as compared to other cars but they are designed to. I used to drive a Toyota MR2. In my 2, if you got over 200 degrees, something was seriously wrong with your car. But then again, that car had 3.5 gallons of coolant and the radiator was in the front away from the engine heat and had a opening in the front of the bumper for fresh air and not a "bottom-feeder" like the C5.
Sounds like your right on target.
