Holy crap, large picture. But it helps actually. My need maintains itself inbetween the line for 190 and the dotted line, of which I don't know what it means. I was always under the impression a normal cooling system will always run around 5-10 degrees hotter than what the thermostat is rated at. I've got a 7 blade clutch fan from my suburban (only useful thing that pos did), new HD clutch, newer water pump (HD unit for an 85 GN, normal rotation), new heater core, new t stat, newer Champion radiator (not the frozen one), new belts, everything. Temp gun is consitent in 180ishto 190 temp readings as well. it never even cracked 200 (passed the dotten line) during break in. After shutdown it will climb to around 230, but start it back up it goes back down to 190ish within a few seconds. No weird temp spikes, heat works fine, everything seems to be ok.
