Howdy everyone, recently purchased a 2014 ram ecodiesel and got a p0128 cel. I noticed my coolant temp is hanging around 177 to 185. It's that normal? From my research it's on the low side. I am thinking the thermostat is stuck open and might need to be replaced. Had anyone else had this issue? TIA

I am no longer getting a p0128 since I replaced the intake manifold, coolant flush and tuned... However.... it takes about 30 miles of 80 mph driving for my water temp to steady out around 204 degrees F. Ambient is around 40F.
Before that 30 miles of highway truckin, my water temp would hit 203ish, than drop dramatically to 175F. I think whats happening is the Tstat and the variable shutters on the grill are not stoicometric. Once things really start to heat up, then it holds steady.
