Quality Thermostat
Runs at desired temp. Truck started to run a little hot in the warmer summer months. This helped keep my temps down.

2012 Laramie Longhorn - jakedele

Runs way cooler than expected
I have replaced thermostats, but this makes my truck run around 160 degrees oftentimes. Which is weird because I’m in colder climate around 30-45 degrees Fahrenheit. I think this one may be stuck open. I was expecting the usual 180-190 that most people experience with this thermostat. Not sure how I feel about it yet. I have a tune set up for it so I have to run a 180 t stat but it seems to be stuck open. Easy install obviously and seems like good construction.

2022 Big Horn - TimK
Keeps temps down...but...
It does keep temps down, but please be aware that all newer RAM trucks come with temperature shutters in front of the grill that open and close to raise temps to higher levels. This has been a tricky one to overcome, as the computer dictates the temperatures the shutters open and close. Yes, my initial temps go down to 185, but they do rise back above 204-208 before fan kicks in and cools it down again. Read about this for your RAM.

Fast shipping. Took less than a week. Straight install. No fab work or extra gasket. Gasket included. Vegas has been running in the 120 degrees this summer. Temp gauge runs lower than normal now. Thank you Mishimoto and AT for your service!
