[The83RangerMan]

the only guages that work on my truck are the speedo, and temp. I took her for a little spin was gonna go run a couple little trails since i havent used 4 wheel drive in a while get it all nice and lubed up, well temp was running warmer than norm so i took the freeway home, I get home pop the hood upper rad hose is kinda warm and lower is cold. so id say its time for a new therm i was hopin to not have to do it for awhile but i have no clue how old it is and better safe than with a blown engine

yeah i would say it's your t-stat, make sure you put it in the right way!

might want to flush your coolant at the same time... just because...

see if you can get the t-stat housing gasket that is sticky one side, makes it much easier to install t-stat, you put the t-stat in the housing, the correct way, remove paper from sticky, put gasket in place, then install housing, gasket and t-stat as 1 piece
