I'm Running too hot....
I'm Running too hot.... 
My LT-1 gets really hot in stop and go traffic (~225°F). It's been like this for a few years and I want to run cooler. I replaced the water pump, thermostat (180°F), and flushed the system and refilled with 50/50 green stuff. At speeds above 50mph, it sits right around 180°F so it seems the thermostat is doing the job... In stop and go, it climbs slowly to about 225. But if I run the A/C, it forces the fans to turn on and the temp is just above 210°F. Even ~210° is a little unconfortable for me. The dealer tells me that they only sell 180° stats for the 95 LT-1. I thought about using a 195°F stat (like in the LS-1) so the coolant would have more time to cool off in the radiator but I know its not designed for that. Maybe the fans aren't sharp enough or spinning fast enough. I wish I could remember what it did when it was brand new, but I don't ever remember being worried about the temperature.
Anybody got any ideas?
The LS1 'stat is called a 180 and its actual pivot is
about 194F. The "160" ones pivot about 177F. Your
car probably has a similarly stupid set of fan on/off
temperature settings, but I don't know what tools
are available for tuning your model year. I'd look to
TunerCat first off, see what-all is involved (hopefully
not having to crack open the PCM case but if you
gotta, you gotta). Other alternative is a manual fan
switch or a thermostatic fan controller.
