Temp gauge sender

[Billy6]

Does anyone know if flatty 6 volt temp gauge senders are still available? Would a 12 volt sender work? 1940 plym P10. Thanks!

There is nothing electrical associated with the temperature gauge sender. It is a either filled capillary bulb and tube. This should be covered in your service manual.

Yes the electrical temp senders and gauges came later, in the 50s.

Unless you have a later engine and the later gauge, yours will be a mechanical gauge with capillary bourdon tube.

The only part electrical will be the tiny bulb that illuminates the gauge in your dash.

Thanks! the temp gauge is missing from the dash and I just assumed it was to be an electric unit. The temp sender hole in the block is plugged with a iron plug. So now I search for a capillary mechanical gauge.  That'll be interesting to try and find. I suppose a later electrical gauge and sender would work, wouldn't it?

Last I checked there were still "mechanical" temperature gauges available in the bubble pack section of my local auto supply store. It would surprise me if that were not still true.

they still out there and as a add on accessory about any one will fit the bill.  But as an added note to some here that has a bad bulb stuck in a head and damaged on removal and wish to graft per Tod's instructions/technique and keep the factory gauge head and placement...watch for the better built units and larger tube size for ease in grafting
