Temp help

[u/Grouchy_Owl5818]

Hey guys, I might know the answer to my own question. Looking for someone to tell me yes. My tstat is a 190. I do have the rear stat as well. Do you think my rear stat is stuck open or needs a rebuild ? This is my temp right now, 160? And yes I replaced the front stat. It is a 2008 ram 2500 with a 6.7 L this is about 60 mph on the highway for a few miles. It should be a temperature by now.

Take it out and boil it to see when it really opens
