James,
The first thing I would do is verify the accuracy of your temperature reading.
If you used a laser thermometer you should place black electrical tape on the
surface you are measuring, then,if your meter has adjustable emissivity, set
the meter to .95 emissivity. Aim the laser at the tape, and be sure you're
within the spot ratio distance so the meter only sees the tape. That should be
a good number. As for calibrating the gauge, I'll let other, wiser people guide
you on that.

Subject: [Tigers] Temp Gauge Accuracy
Hi All,
My Mk1 is back in the garage after a long winter's rest and some work to
address body panel issues. One of the things I wanted to do after reading a
thread from a few months back, was to check the accuracy of my gauge using a
laser thermometer.
Well I did that today and to say it was off is an understatement. After idling
for 30-45 minutes the temp at the radiator and thermostat was
185...unfortunately my gauge was reading only about 150-155 (needle about half
way between 120 & 170.)
Since I did not save that thread...can somebody give me a rundown on the best
way to get my gauge in sync. Hopefully, it will be within my technical
capbilities.
Thanks,
Jim
