Smile Dead Horse (180) stat

I just wanna know from people w/ a 180 degree T stat installed in a 2012 ram 5.7 hemi who live in the north east or any other comparable climate place whether or not they have heating issues when it goes winter on them. I see temps sometimes on average 30 degrees some times teens & single digits in the dead of winter & I not only consider my ram my toy but first & foremost a family vehicle. That said I can't have my child freezing in the winter just cause I want a cool running engine. Any responses would be appreciated & let me pre thank all that do so.

You guys don't know COLD! When it gets too cold for snow, then you know it's bad.

BUT, to answer the OP's question, I ran a 180 t-stat for years in my '07 and have one in my '09 now. We see temps well into the negatives, both Celsius and Fahrenheit, and both vehicles are able to pump out enough heat to allow me to cruise in a t-shirt and the wife to remain bundled up complaining that it's too cold (but she does this in Mexico sitting on the beach too ).

The t-stat just allows the coolant to start flowing through the radiator sooner, your high temp will remain very close to what it was before the t-stat swap. Warm up times are affected in a very minor way.

What's the benefit in running a 180 stat in the 5.7?

I run a 170 here in PA and never have any issues with getting adequate heat for the passenger compartment during the winter.

Seems like a waste of time and money to me. No real data that it does anything. Do it while still under warranty and you give them an easy out if something related happens.

No pun intended but there's plenty of data that it does infact icrease the performance of your engine. You won't find an engine builder in the world who would disagree unless he was an idiot, lol! And they can not use it against your warranty. The only thing it will affect if it does is your emission test more than likely for those with modded exhaust systems. Although hotter engine temps do help burn off emissions better I have'nt heard of anyone failing emissions using a 180 tstat alone. Hotter engine temps help burn high emissions but rob your engine of performance where as cooler 180 temps don't burn emissions as well but increase your engines performance.

I could have been wrong. My wife seems to think it happens more often than I do for some reason. Maybe someone who is building will find the benefit but most I see are just changing the thermostat and looking for a noticeable difference. Much like the CAI debate. By data I was thinking more on the lines of a truck outlasting or beating one in a race without and not so much on paper numbers. How much performance can you get from a thermostat change? Is it worth the chance? Just a few things to think about I guess. I don't claim my post is expert advice. I'm looking for the input to them. Even though I'm not doing these changes I am very interested in reading about those that do.
A warranty can be voided extremely easy. If you change out engine parts and screw something up or the failure can somehow be linked to the new part you can bet that they will drop it. Dealers need the warranty work so most aftermarket parts are overlooked during minor repairs. Try that with a blown engine.
