Temperature Gauge Question
Can anyone tell me what is the correct temperature in degrees at the first line (at around 10 o'clock) before the next middle line 210 mark on a 1967 Temperature gauge? Is it 180 degrees? Thank You -

I don't know for sure from any design standpoint, but the consensus has been that those marks represent even divisions on the gauge.
With the lowest mark indicating 100, and the middle mark 210, that's 110 degrees of range. The mark in the middle thus would be 155 (100 + 110/2) assuming the gauge is linear as we suspect.

The 210 Mark is "OK but you do not want it to get much hotter",
The third Mark is "You better get this thing cooled off"
And the last mark is "Bail out, She's Gonna Blow"

Looking at the face of the gauge it would seem to be very non-linear. On the left you go from 100 to 210 but in the same space on the right you go from 210 to 250. To approximate the middle mark on the left you can ratio total gauge lower half to total gauge upper half and compare that to left half lower portion and left half upper portion. With that the middle mark on the left figures out to be about 180 degrees. My original 170 degree thermostat seems to settle just slightly over the middle mark on the left so (while not exact) that sort of confirms the calibration.
