Solid unit, steady temps
Great little unit. Installed in a 2012 Ram 2500 and pulled several 12k trailers back and forth between Florida and Texas, steady temp now where as the stock units tend to cause the engine to run higher going the same routes (210-220 degrees) so satisfied with its performance.

Get something else
Buy a different thermostat. This one is junk. Mine failed after a few months. Contrary to the description, mine didn’t fail open.

Change out thermostat after 13 years and it worked out great. Highly recommended as this is really accurately rated.

It fits 3500 2016 ram 6.7 Cummings
Used in my 2016. Dodge Ram 3500. It fits fine, but the temperature it fails to stay consistent fluctuate from 192 to 205. Honestly, I never paid close attention to what the original. Thermostat did for the first 100 k
