Someone may have put a 160* tstat in there cause thats where mine runs also 98 are the only cars with accurate gauges 99+are just dummy gauges which will only tell u when you are overheating.

If your going by the gauge its probably off. Mine sits under 210 but verified with a computer really runs around 215. and contrary to what was said above running a thermostat jammed open will actually cause the car to run hotter because the coolant doesnt have enough time to cool down in the radiator.

Complete internet heresay regurgitation......
nncfan8 prolly nailed it. That is right where my 98 runs with a 160* t-stat....

The '98 is more sensitive, and will show much more minor changes in temp.
I've spent time monitoring actual temps (via my PCM scanner) vs. what's shown on the gage on both my '98 and my '02 car. The '98s are definitely more sensitive and accurate.
The factory T-stat is an 86°C unit, which converts to 186-187°F. The factory fan settings will allow the coolant to reach temps into the 230° range under some conditons. I stick with the stock stat, and tune the fans to never allow coolant temps to exceed 210°F. While cruising, my temps are usually in the mid-190s.

The '99+ gage is much less sensitive to changes in temp. It will read right around 210° for actual temps that are anywhere from 190-230°F.

The computer is not set to run "best" at any temp. There are spark and fuel maps for all temp ranges, anything above 176°F is considered fully warm by the PCM. Now, that's not to say that the engine doesn't have a "best" temp, and I agree that a T-stat should be used. My experiance is that my LS1s seem to run best in the 195-205 degree range.

So is running a 160 tstat a bad thing? What are the advantages and disadvantages of it? I just bought a 98 that I suspect has a 160 in it also, but the car seems to run fine with it and the Texas heat is coming soon.

Personally, I would never use a 160 stat for most NA setups. On the other hand, if you have super high compression, or forced induction/power adder, then I would consider it depending on climate.
