CST 180* Thermostat for 5.7L and 6.1L Hemi Product Code: 41680 works great. I ordered mine from Moes.

Hi AzCats, and anyone who might want to chime in...
I live in Northern Nevada and temps go beyond 105 degrees in the summertime, and we also have four seasons. Would a 180 be preferred, and if so, what can I expect in terms of benefits? Are we saying that since the engine will run cooler, over time it will gain longevity due to the high flow, lower temp design? I'm not sure how good the stock thermostat is - but anything that will do right by my truck is alright by me.
My only other concern would be normal operating temperature. Any issues with running too cool?
Thanks for your input.
Regards,
Maitai

That's the suggestion. Cooler engine=better performance and longevity

If I am not mistaken you can run a faster tune with a 180 T-Stat, but I do not know that for ma fact ?

I think your tuner can add a little timing if you change to a cooler thermostat. You can check with Sean at Hemifever or Matt at Moe's Performance.

Thank you to Ramitimer, Mints, Witch, and Pull Ya for your answers.
I do not have any kind of tuner chip as of yet - I'm working on some other stuff like switching to leather interior, etc. I'm going to reach out to Sean and see what he says - and Ramitimer, thank you for reinforcing the idea.
Many thanks guys,
Maitai

You can run a 180 T-stat on an untuned truck with no issues. I ran around for a couple months with a 180 T-stat,before my truck was tuned,and my wifes untuned 2016 Challenger has been running around for a year now with no issues

Hey sorry I just saw your post. What year and model do you have? I run a 180T on my 2012 hemi without any issue before and after my tune. You should see lower temps and might see a difference in -1 MPG. Like the others said lower temps should mean happy engine.
Also, some have reported active shutter issues if you have that on your truck. See video.

Sean just added 180 Tstat in my Diablo T2 93 tune. I haven't installed the actual thermostat yet though. @AzCats that is a great public service announcement. Glad I have my 2010. That would suck if you missed that FYI.

Hi Guys,
2014 Ram 1500 SLT with 5.7 Hemi. I do not have active shutters on the grille.
AzCats: Are you saying I might see a decrease in MPG? Reason is the way you expressed it as "-1."
S0CAL: What do you mean he "added it," but it "hasn't been installed yet?" Do you mean the programming for your tuner? Sorry, I'm way noob when it comes to tuners...
I just like the idea of higher GPM flow and a cooler running engine. All the comments here seem to support that. Thanks guys, I'll share any other info I might get when Sean responds, but I'm pretty much sold on the idea.

Maitai

I compromised and went with a 190* thermostat because we get cold winters here in New England. I just felt 180* might pose some heating issues. I used a Stant 48799 thermostat https://www.amazon.com/gp/product/B00CMN7XOY/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
Throwing this out there as an alternative.
Sean did have to change my tune to accommodate it.

I don't get it, are you saying your truck's engine regularly overheats? Or do you just want to put in a cooler t-stat because it'll make you 'feel' better that your truck is running cooler?
Car mfgrs do a lot of hot weather testing and engineering. There should be no problem handling NV weather ....millions of cars/trucks successfully do it every year. I've driven a lot in temps up to 119 degree with the A/C on all day, and never have had problems.
I would personally hesitate before doing it. If your engine is overheating, deal with whatever issues are causing that (plugged radiator, collapsing lower radiator hose, failing headgasket, etc).Otherwise you would be subjecting your engine to premature wear running outside of engineered temp range. Running cooler also leads to greater engine deposits.
Either way, good luck, let us know how it goes.

Thanks Fellas,
Jeepwalker: No overheat, but I do live in the desert and we get some of those high-degree days - I'm looking to make a big enough change without affecting performance in the other direction during wintertime. It might make me feel better, so I'm just pulling in all the scenarios either way. Thanks.
