replacing T-Stat
I searched like crazy and couldn't find crap towards tips on replacing the thermostat.
Going with a cooler stat as it is 100 degrees here in STL and want to make sure I don't leave any air trapped in the cooling system.
I know how to replace but not sure what the trick is to get all the air bubbles out of the system.

Simple technique to purge air from the cooling system. …There are two hoses on the overflow tank. Follow the smaller/upper one until you reach it’s junction point. Remove that connection. Fill the overflow tank and put the cap on tight. Blow into the overflow tank via the line that your removed. This will force coolant from the overflow tank into the cooling system. When the tank is empty, refill and repeat. Continue doing this until fluid begins to exit from the other end of that hose connection you removed. Reinstall hose. DONE! Works like a charm!

Great info! Thanks for the quick response 
massaging the hoses, sounds like both top and bottom. I am using the stat I bought for my 2005 GTO a couple years ago but never used, I understand they are the same application.
Thanks again achilds

Some people consider the technique I described a bit crude (lips on overflow tank hose) but it really works very well and requires nothing more than a very minor topoff in the reservoir after a day of driving. I've tried other techniques but IMHO this one works the best and is quick.
Besides, are you really working on your car if you don't get to taste gasoline, oil, transmission fluid, power steering fluid, brake fluid or maybe a wee bit of Dexcool?

Drop your new thermostat in a pot of hot water with a thermometer to check when it opens and closes before installing in your vette. Some thermostat temp ranges are poor.

Some arent as advertised and open way too soon having you run at 158 where the tune fights it.

good to know SpinMonster, I found the receipt and it is an SLP 160 so I will do the pot of water on the stove trick with a cooking thermometer. If it is to low I will pass on changing until I can get my hands on a 170 - 180.
SpinMonster, in your experience what is the most optimal temp stat?

feeling pretty good about the stat, it starts to open at 160-162 and is completely opened at 182 degrees. tested three times for consistency.
Looks like the swap is going to take place.
Thanks for the help everyone!

Best upgrade I did was to go with a 160 degree thermostat. I was running up to 217 degrees and when I changed to the 160 it doesn't get above 190 which is fine with me. Don't foget to use distilled water instead of a garden hose. Look at your glasses when they come out of the dishwasher and you'll see what hot water from the city water supply does to your engine and radiator.
