As background, I am running an OEM thermostat. Unsure of the exact temp rating, but assume it’s 180* (actually thought it was 185*). I ordered it through @cruiserdan back when I bought the truck and overhauled the cooling system. That was about 75k miles ago. I also run a blue fan clutch with a new fan and just replaced the cowl a few months back. Foam gasket around the radiator makes a solid seal. It sounds like all of this adds up to a new engine finding it’s center, and a well functioning cooling system. All good stuff.
