It's all on what you wanna' do bro. If you just like to cruise with the a/c on and don't mind seeing the 200-210* needle, then run the 180-190 thermo. I like my shit to run cool.

And matter of fact, along with my 160*, a 3Core Griffin Radiator and 20" electric 3 speed fan are gonna make there way into my truck soon to match my Edelbrock water pump.

Ain't a problem dude.

I alway's took the serious advice from the guy's that did the shit first hand and had good luck with it. Not the hear-saying queer bot's. Feel me pimpin?

Colton, you can do whatever you want to do and there are always several ways to get it done. The 180 stat is a widely accepted mod. If you want to run cooler, just keep in mind the parameters I mentioned about oil temperatures and cooking off moisture. If you really want the 160 stat and it is throwing a low temp code, then manipulate the sensor so it is telling the PCM it is hotter than it actually is. Remember the PCM has a list of sensors it gets it's information from and it continuely tests these sensors to see if they are providing valid signals within a predetermine set of values. The hole in the thermostat housing is a air bleed hole, it often has a piddle valve in it. (loose rivet), I always remove the rivet (piddle valve) or if it doesn't have one I drill a 1/16th inch hole in it to remove trapped air. I recommend you experiment and come up with your own conclusions. Good luck..

Pretty much the best advice you're gonna get. Well said Greg.

I too had a code thrown with the 160 degree thermostat. I am sure you won't this time of year, but when it dips down into the 30s you will more than likely get the P0128 code, which means, "coolant is not reaching operating temp within the specified time interval." Your not going to gain any seat of the pants performance by running a 160 thermostat over a 180. Its a thermostat lol. Go with a 180, and use the Stant Super Stat, it is extremely beefy and will never fail on you.

So, a cooler engine don't run better than a hotter engine....?

Ofcourse a cooler engine will run better, but a 20 Degree difference on a bone stock motor that makes 170 horsepower to the rear wheels? Really no performance difference. He won't be very happy with it in the winter time either when he keeps getting the P0128 code.

If we were talking about an older vehicle with no on board diagnostic system, I would say run a 120 degree thermostat!

And something to laugh at, I called a dealership and talked to the service dept. The guy I talked to said if you get a 160 then you will crack the heads... LMAO guess he doesn't know that it's HOTTER temps that will do that. I suggest that that guy go work at mcdonalds or something lol
