AC on or off? 90ish is more better. I see all of mine hit 100ish at
times. This is normal and I see a little more when pulling a big long
hill, it always cools back down.
Did you point the arrow on the thermostat up and/or the tiny orifice?
So I am thinking I have a clutch-fan issue too (though
the viscous aspect of the clutch fan is near perfect).
There could be a 20+ year old pile of dead bugs, dead vegetation and
general debris on the forward side of the radiator, (between the
condenser and radiator).
Has it ever hit the red on the gauge after you burped it and topped
it off? I wouldn't sweat it if it hasn't. It wouldn't hurt to check
and clean the sensor connection to ensure good contact and accurate
readings. An acid flush can surely help if there are mineral deposits
in the radiator tubes.
Bruce Dike also had a theory that erosion of the inside of the
thermostat housing can cause overheating, JB-Weld or a new housing
can remedy that.
Was the original T-Stat stuck open or closed prior to changing it?
