So I noticed a slight smell of anti-freeze in the engine bay. Dont see any leaks. While driving around in 45degree weather the coolant temps were going from 190-210 driving around and 220 idling. Thoughts?
I had the same coolant smell but no leak issue for about a year. When I had the accessory drive on the front of the motor apart for a recent mod, I noticed the "three way hose" from the heater core to the water pump and the coolant over flow tank was seeping coolant from the hard plastic three way connection. I replaced the hose and the smell is now gone. Might be worth a look.

thanks. I'm gonna see if I can get it on a lift later today... I was concerned on the temps as I'm new to Vettes.
As mentioned, if you have the OEM hoses, then the T section has a tendency to get brittle and start to leak. I just sold my OEM hose for that exact same section to a member about 1 month ago. I had replaced the OEM hoses with a silicone set, which has a molded T section.
The other places to check is for drips or leaks at the connections of the hoses to the radiator and other areas.
My leak was from my water pump inner seal that took awhile to find because it was dripping on the WP pulley and the heat was causing the coolant leak to evaporate.
I had to do a cold air pressure test on the system to finally see the drip.
Here is what the WP pulley looked like from behind. You can see the accumulation of the dried up antifreeze.

if I have something going on its not evident yet. Looked and cant find any seepage/leaking etc. Its gotta be very little at this point.
after I looked thru it today I drove around for a while (which was fun : )) and then let it idle for 15 min. It got to 217degrees. I guess that is normal temp.
When your pump was leaking did you lose noticeable quantities of coolant?
As far as the temp goes, checkout your radiator to see if any garbage has collected on the front or between the air conditioner condenser and the radiator. Very common issue with higher temps.

Are my temps high? Im getting mixed opinions I guess. 185degrees on the highway. 190, 200 driving around. As high as 220 after idling for 15 minutes.
My car has 30k miles on it. The engine bay looks like a new car. Zero dirt, buildup etc.

The highest I ever see after idling is 208 degrees.

Here is the stock fan table.
Temps up to 225 are to be expected with an unobstructed rad when there is no air flow (i.e stuck in traffic, idling for extended periods). There is also some interaction with the AC system that causes the fan to ramp up sooner if pressure in the AC reaches a certain point.
At 221 and above, you should hear the fan roaring away. As others have said, your temps are fine. GM designed it to work this way.
You might have a slight leak if you smell coolant. But, if you only smell it sometimes when you are in traffic, you might be smelling someone else's coolant leak. I've got a pretty sensitive nose, and I sometimes smell coolant in whatever car I'm driving, but it disappears as the cars in front of me move on or away, so I figure it's their car and not mine.

That is great info. Thank you.. . Its very possible I'm being hyper sensitive. Just did the Headers, Xpipe etc. Now I keep sticking my head in the engine bay, lol... I'll keep looking to see if there is seepage or something...
Coolant temps?
