Installation of Temp Gauge

[tbirdtbird]

why use that gauge?
The dial has a very small sweep, thus is not very accurate.
The probe is mechanical, in this case filled with ether which expands with heat. Can be troublesome
Why not use an electrical sender, that way you are only running a wire
Your FLAPS will have a bunch of temp gauges to choose from. Getting a black and white face is no problem, or whatever you choose. The sender and gauge come in one box. Large sweep= much greater accuracy. Marc H. can better explain why this is than I

I did the hot water test of the sender unit in my top his connection, gauge worked fine, This being a car new to me I hadn't tested it before and had never seen it move much if at all. The hot water had it shoot right up the scale and it coincided reading with a thermometer I had placed in the water. I'm good to go for a while at least. Thanks for the tips on a replacement gauge when the time comes.

When shopping for Mechanical Temp Gages or Moto-Meters @ swap meets, take along a BIC lighter to test them with. When buying new repro temp gauges, test them in boiling water, to see if they're reading 212 degrees. Chuck went through 4 new NAPA gauges, to get one that was ACCURATE! (Made in CHINA!)

What are the FLAPS that you are referring to ?

I've found the opposite to be true; electric gauges available at my FLAPS are off often as much as 20*. I prefer to stick with vintage SW gauges or the original Rex-A-Co units made by US Gauge in the 1930's whenever possible; both are quite accurate.
