Re: Temp sensor help needed



Remember, simple is NOT the same as easy.

The "fluid", in the bulb, that your are working with/against, is ether. Highly volatile and flammable.

Dry ice is the key component, freezing the bulb, of the new gauge, while prepping everything is a big key to the success of the project, as is making the splice a good distance away from the back of the original gauge back. It's quite easy to un-solder some of the gauge components.

If you have more questions, before attempting this, e-mail me and I'll try to answer them. I've done this several times.

Thank you Vern,
Repairing temp. gauges has been one of several "You can't get there from here." Crosley mysteries. Your description makes the fix easy.

One can repair these By purchase a replacement gage, Freeze the “blub” (the part that screws in block) so the fluid will not leak out. Cut the old “bulb” off leaving enough tube to solder new bulb cut the new froze bulb. With a peace of 1/8 inch ID.  tube spice the new bulb to the original tube  then solder.
Note: You may want to make the spice so it will be under the dash out of site.
          Install new blub and gage in freezer Do not cut until you are ready to spice the two together.
          Dry Ice is best if one can fine it.
Good luck.

The block thread is 5/8" X 18 (as I recall)  fine thread.

The chances of the tube being just kinked and not working, are slim. If it's not working, most likely punctured and leaked the fluid out.

I'm looking for a little help and advice on the engine temp sensor. I accidently bumped the capillary tube while replacing the battery on my Hot Shot and now the gauge doesn't work. The end that goes into the block appears to be undamaged but there must be a bad spot on the tube. If I could locate the damage on the tube is there any hope in straightening it enough to make the gauge work again? If not, I have a couple other questions to clarify things:
  • Does anyone know the correct thread size where the bulb goes into the block? I bought a brass plug with 3/8" pipe thread but it appears to be a hair too big. I'd like to plug the hole so I can drive the car a little while waiting to get the gauge repaired.
  • Does the backing plate that holds the gauge into the gauge cluster on the dash have to be removed along with the gauge? I took one out about 20 years ago to get it fixed but don't remember this issue.
  • Does anyone have a recommended place to get the gauge repaired now that Bob Potts is no longer doing it?
Thanks for your help.
