That way it would never stray from 210.

GM probably did the same thing as they did with the LS1's. Those temp. gauges never move either.

If you look closely, you'll notice that there's a small pin that prevents it from going any higher....

No SS LS2 here, but this is probably a good example. When my gauge is reading 210°, the actual temp I recorded with my Carchip during the July heat in 2004 shows it stabilizes right at or just under 200°. The gauge seems to read about 10° too high.

So if we start to overheat the guage won't show it>Its pinned at 210.

[COLOR=black]Is the gauge buffered? Most of my recent experience with newer auto technology has been with the BMW make. On both of my BMWs, the temp gauge is buffered. The temp can move around some but gauge stays put. If you start overheating, the gauge quickly rises. It doesn’t go to red line but you know you are running warm when it moves. I am not sure the logic behind it. Did Chevy adopt that same process on the SS? My gauge hasn't moved off 210 for 1700 miles, except warm up. If it’s not buffered, that Tstat is doing a good job.[/COLOR]
[COLOR=black]In reply to a couple previous post on lowering the stat. If the engineers designed for 210, why drop the range? Or is 210 to lower emissions at the expense of power?[/COLOR]

The gauges are just there for show. 210 looks good on the gauge. the engine coolant will actually be warmer/cooler than what the gauge says. If you plug in a Tech 2 it will show the temps much higher than what the gauge says. It makes people feel good to see the 210 and the best part is that the supplier doesn't have to re-calibrate or print a new gauge face from truck to truck with different engine packages.

Changing to a lower thermostat might cause other problems such as internal engine problems and poor heater performance. If the thermostat never moves of 210, then I wouldn't worry about it since it seems to be operating at its designed temperature.
