Water Temp Gauge

[Editor_Reid]

You often hear "maybe it's just the gauge" when a Healey is indicating that it's running hot. So just for fun recently while all of the instruments were out of the car (a RHD BN2) during restoration, I took the gauge into the kitchen and boiled some water. With the probe in the boiling water the gauge indicates 212 degrees. I was impressed. The gauge is 65 years old.

I don't have a question and just thought you might be amused to see this pic.

Agreed. Used a Garmin NUVI with intent to "calibrate" the 58 year old speedometer on my BJ7, but results were unexpected: The speedo was "spot on." This was before the rear end was rebuilt with 3.54 gears. The speedo is more pessimistic now, biased -7mph.

Reid, that only works at sea level. Compare with an infrared gun.

Reid,
Good idea for folks to check their temp gauge when they get a chance.

I compared my temp gauge reading with two cooking thermometers adjacent in thermostat opening plus a HF infrared gun. The gauge was about 25 degrees high. I removed the glass and corrected the needle.

I've been advocating something like that very thing for a long time: Take the glass off and move the needle to where you like it

I used to do that with the thermometer in my house. If the summertime temp got to 90 inside, I’d just move the needle down to 65 and feel much cooler.
