Here's one thread:
180 Thermostat did wonders!

others:
Supercharger and 160 degree thermostat
05 LS2 Engine Tempature
180 deg. thermostat ?

There are even more if you use the search function....

I changed mine on the '06 and it made zero difference in temperature - still runs straight up at 210, and that's with Mikey's fan and radiator.

Thermostats are for for preventing the engine from running too cold. They have no role in keeping the engine from running too hot.

That is the job of the radiator and fan.

The proper running temp for an SSR is 195 not 160.

The only way that a thermostat can make a vehicle run too hot is if it has failed in the closed position. An exceedingly rare event these days.

a 160 degeee stat will not run at 160,it opens at 160, eng will run approx 15-20 degrees hotter.the stock fan relay[ low ]does not activate untill eng temp is 225degrees, much too warm, not much of a span before eng is exreemly hot.especially this eng,or even almn heads.joe myers,rockpile garage,

Fellow SSR Lovers.

I'm running a 03 5.3L SSR with a supecharger,cam and headers.I had it custom tuned at Tonys' Corvette in Gaithersburg Md.
I asked Keith Green about changing the thermostat and he said that the Corvettes love them.So' he turned me on to one which I installed.He re-set the on/off fan temps during the tune process and i have absolutely no problems with the colder unit.My SSR runs at 160 degrees all the time,which suprized me,but its true,It really makes a difference.I'm pushin 525HP and even at 100+mph the damned thing runs at 160.On a 95+ degree day she runs cool.In real heavy stop and go traffic, it will creep up a bit but goes right back down when I'm rolling again.
Iv'e got to say that I had serious doubts,reading all the posts about guys installing bigger fans and radiators and such,but I'm a believer. Best $40.00 I have spent
Now I don't know if its' a good idea on a completely stock motor,but with the mods that I have,so far it's been a good thing.
