my car runs 180 all day with the 160 except for when the a/c is on then its 190. only had a problem once where it stayed stuck closed and the engine ran to like 280. luckily i didnt damage anything.

SOOO... what about how these things mentioned in that write-up??? :
If they are not running the engine hot enough to boil the water out of the oil, the oil becomes contaminated and the lifter/cam lobe interface is the highest load point in the engine. Engines running too cool can contribute significantly to camshaft and lifter failure.
piston manufacturers’ piston-to-wall clearance recommendations assume you will be running the fully warmed engine at 200°+F. Run the engine too cold, and you could see some scuffed pistons because the cylinders had not expanded enough to provide clearance
The internal combustion engine changes chemical energy stored in gasoline into heat energy that is focused on the piston tops. If the cylinder heads and engine block are too cold, they will absorb much of the combustion heat before it can be used to push the piston down the cylinder.
running a computer managed engine at 165°F compared to the factory 210°F will often cost you as much as 4 MPG. The reason for this is that the computer thinks that the engine is not off the “choke cycle” and it is still putting out a rich mixture!

does anybody think this is true?

About burning off water, I guarantee that an engine running at 160* could still burn off moisture. Oil temp runs significantly hotter than water temp. I used to run an oil temp gauge and it would reach 250* if you were driving a few miles.

plus water doesnt have to boil to evaporate, unless it is stuck at the bottom of the oil. im thinking of getting a 160 stat tomorow, does anybody know where i can get proof of it actually doing any good, say maybe a dyno sheet or a thread? just want to make sure its worth losing what little heat i have coming from my heater

the only reason gm made these cars run so hot was to keep emissions lower.
as long as the car gets into closed loop(which is 140 degrees) then you are in good shape. if the car never gets into closed loop then youre running on a written program (open loop) and the computer is not using all of the vehicles inputs from 02 sensors, map sensors, ect...

ive had mine in for some time now along with my hypercrap tuner i got wit the car that turns the fans on at 160, she never breaks 190, even in last weeks heatwave stuck in traffic for 30 mins, she never got hot
i installed a 160 stat,with my madwolf tune a few years ago. no complaints. car runs cool even on the hotest days. great throttle response.
