160° Thermostat
A scanner will read accurate engine coolant temp.
While driving at highway speed in reasonably cool weather, see what temp your engine is running at...your thermostat is probably within 5degF of that temp assuming your cooling system is working properly.

To get the engine to run at a certain temperature, the thermostat and the PCM’s fan turn on temperature need to match.
If you have a 160 degree thermostat but the fans don’t come on until the temperature is 210 degrees, your running temperature will be 210 degrees.
The running temperature will match the higher of the two.
If you in fact have a 160 degree thermostat installed and you’re still running 210, you’ll need to have the PCM checked to find out it’s fan turn on settings.

160* Tstats can often collaborate with nonconsistant tuning temperatures to mess your tune up. I run a 192 tstat (or whatever * it is that SLP sells) and it does just fine.
160 tstats are for old chevy engines. lol.

Quite right, meent. Here in the NYC area, the words "highway" or "expressway" usually mean walking speed traffic jams.
To the OP: On the highway at speed, does the gauge start to drop below where it is when sitting in traffic?

Needless to say, I didn't think about that. 
I heard its not good to run 160 thermostats cause the ls1's run the best stock. They need to get hot to burn the gases up to be efficient.
160 stats being bad for these motors is a complete and total myth. I've installed 100's of them over the years.
To the original poster. FYI, you can have a 160 stat in the car but if the fans are not programmed to come on earlier your car will still run at near stock operating temps during city driving. Only while HWY cruising will it cool down. The fans needs to be dropped in the 180 degree range to take advantage of the thermostat.
This is true for emissions purposes. Most of the stock heat range specifications are designed around the engine being able to burn off enough gases to pass emissions.
