What thermostat should I use?
All,
I had my car dyno tuned and the fans come on much lower now (around 190 degrees). I was debating adding a lower temp thermostat to compliment the change. What does everyone think?
I do live in the northeast and the car is driven in the cold weather.
What temperature stat should I get?
160 degree
170 degree
180 degree
Stock

Use a 170 - It should warm up and cruise in the lower to mid 180's until it has a reason to rise such as traffic or flogging your engine. Your fan settings should keep the hot stuff away unless you need to clean your radiator and/or condenser.

I have a 160 but for you with those cold winter, I would run a 180. If it still runs too hot, you will need a larger aftermarket radiator. The radiator was way too small in stock C5s, especially for hot climates.

I run a 160 tstat, and drive year round, temps in the 20's to 100's, and my coolant temp is in the 170's and 180's winter, and 180's to 195 top, in the summer. The oil temp gets high enough to get rid of any condensation if you do a little "spirited driving", it doesn't need to stay over 212 all the time for that.

Even in stop and go city traffic, with the A/C on, I never see coolant temps above 195. Now that is with a 160 tstat, water wetter and re set fans.
If the radiator was too small the temps would climb beyond this point. It's not too small.
If you are having high coolant temps look for the problem somewhere else; fans not operating, gunked up radiator, debris in the radiator fins.
