I had to go to town again this morning so I checked some of the items suggested. The truck warmed up quickly; in about 2 miles the indicator was halfway between the bottom mark and the middle (the outside temp was 33). I turned the fan on and the temp was ‘meh’ coming out the bottom, about what it usually is. When I got home I left it running and put my hands on the heater hoses and they were both very warm on both sides of the shut off valves I have installed. They were cool enough though that I could leave my hands on them. After I shut off the engine, I carefully removed the radiator cap and the water level was about a half inch down. Just a little higher than when cold.
So for now, I think my issue is a thermostat that is either opening early or it is maybe a 160 variant. I’ll get me a 180 and some gaskets and swap it out.
Thanks for all the ideas.
Lee.
