Hi, Patton -
The hardest part is removing the gauge sensor from the head and then
removing the gauge from the dash while you thread the sensor line through
the firewall without kinking or breaking it.
After the gauge is removed, you can check the calibration by sticking the
sensor in a pan of boiling water and checking to see if the needle
stabilizes at 212F. If not, remove the gauge bezel and glass, pull off the
needle (carefully), and then reposition it to read exactly 212 with the
sensor immersed in the boiling water. You and I both live at or close to
sea level, so this is accurate enough. You can use boiling distilled water,
if you wish.
I tried to calibrate the gauge without removing it from the dash, but it's
difficult to keep the water actively boiling in a container without having
it on the stove.
