So I’m getting ready to do a few more mods on my 06 C6 (halltech CAI, ported intake, throttle body and a tune) and I was considering adding the 160 degree thermostat to the list but I have heard mixed reviews on this mod. I know the idea is to make the motor run cooler, but what is the down side of the install? The heater not working quite as well?

before any mods, my 06 Z51 ran in the 200-220 range in traffic after crusing hwy speeds(55-70) and that was in winter time. After the stat and tune, I get a nice 180-185 range no matter how much I put into it. Granted there is still some instances where it gets higher, but avg 183. It won't do you a bit of good just to drop the stat in, though. You'll need to tune the fans to come on when they need to or else it'll act just like stock even if you have a 100 degree stat.

There was quite a bit of discussion (debate) concerning the benefits of using a 160 Deg stat on the new C6 vettes. Seems that the rate of opening, etc. for the stat is all computer controlled --- so even if you drop in a low temp stat, you may not reap the kind of benefit that you think you are going to --- unless you reprogram the computer as well.

heat

Down here in texas where the temps are above 100 during the summer, its all most a must. The cooler the better down here.

correct because unless you reprogram the engine will be running too rich at the lower temp.

You need to tune for fans anyway, all programming changes should be done during the tune. I change the t stats in my Vettes as one of the first mods done. Then tuned.

I would not

I would not change the temp, I heard that you need the 180 to make sure you boil off the water and condensation in the oil. That’s my two cents.
