1970s Thermometer Calibration

[Big Fins]

Is the thermometer on the left side mirror able to be calibrated? Mine reads about 15^ohigher than it should. No mention of it anywhere in FSM other than it's optional. Plus, I don't want to break it.

Nothing really earth shattering to worry about, but something like that plays on my OCD.

No calibration that I'm aware of. On my '76 I swapped the thermometer portion with a know good one of the several I had salvaged from wrecking yards. It can be detached from the mirror housing if you are careful.

Thank you, sir. I guess I had better leave well enough alone.

Its it just pressed or glued in?

No clue. On the forward facing side of the mirror stand, there is an opening where the probe sits.

The lens is still nice and clear and the wheel bright white. I tried gripping the sending probe with a set of needle nose, but again, I don't want to force it. Breaking it all would leave an ugly hole there.

if I recall it was glued-maybe with a putty? Don't try to tap it out from the front as it could crack the clear plastic housing. I recall that I was able to pry it out gradually with a razor blade around the circumference of the clear lens..

The simple thermometers using a coil of bimetal
to turn the needle, may have a coil anchor that
can be turned.  This will shift the reading the
same amount everywhere.  Bruce Roe
