Would it be wise for me to put a 160 degree thermostat into my truck? And if not what would be a good suggestion.

What year, make, model truck? Engine?

FWIW, the LS based engines run better with a 180* or 190* t-stat than a 160* t-stat. It would run slightly cooler with 160* but just because it will make it run cooler doesn't mean it is good for the engine and cooling system.

nope. it would be much cooler if you put an alaskan snow crab in it.

160 is too low. Hell the switching point between open and closed loop is 155*F. You may end up switching between open and closed loop which will ruin gas mileage. The lowest you would want to go is 170. I have a 170 but am also chipped for it aswell. I like it cause it keeps the tranny temps down too.

Thanks for the help I think maybe I'll lean more toward a 180 degree thermostat instead then.

Make sure you get a tune afterwards if you dont have one already.

Leave the stock one. There isn't any reason to even go down to 180. Keeping the engine in its designed operating range will make it most efficient.

alright thanks for the info.

The stock one opens at 186. It will work fine.

I gotta say it, but engine swap? Otherwise it's not a ls1

Pics of said LS1 or GTFO!

Either it's a stock L31 350 which is nowhere near related to an LS1, or it is a swapped in LS1 which is not a "350".

And the lower thermostat will do nothing to benefit your stock engine.
