Re: Temperature gauge not working

Not uncommon for those capillary style temp gauges to leak down over 50+ years.

You can try putting a couple of drops of 3in1 oil on the pivot points in the gauge and try to move them a little bit in case they are seized.

But generally, if they don't move, they have developed a leak somewhere in tubbing or in coil inside the gauge and will need to be sent to rebuilder for repair.

Just about to send mine my 37 one off for repair.
