1986 E150 with 2 bad/obsolete overheat sensors. What to do about replacements?

[Smgbad]

Hi all. Almost done with finishing the general maintenance on this '86 E150 and realized both overtemp sensors are dry-rotted and crumbled to dust when touched. I went online for replacements, and this particular one is not only obsolete, but other numbers that it crosses to are as well. Ebay didn't yield any usable ones.. Just ones that were in the same or worse condition that mine (most of which completely missing the ground wire from corrosion... not even a little nub to solder onto... lol).

Model - E150TLCDC
Part - 0386686

Any safe options here so I'll still know when/if I'm overheating?

Also, there is no model ID on my motor, but I don know it's a 1986 E150.... Anyone know what the dif is between the E150TLCDC and the E150TXCDC?

Seems to me, with a little creativity, you could possibly resurrect the old ones. Those bi-metal thermostatic switches are usually very reliable and also can easily be tested with the application of heat. Assuming the sensors check out, you could clean them up and solder on new leads. Then you could take a trip to the hardware store (or, better yet, look in the McMaster-Carr catalog) and find some suitable type of plug that could be modified to fit correctly.

Desperate times, desperate measures...

When coming across a NLA or obsolete parts, you have to get really creative. If you understand what the part does, then you improvise and substitute to make it work. If you can post a picture or three of your broken part, then we can offer some ideas to make something or repair them to work. If they are merely open or closed type parts for over-heat indication, there are lots of such type parts on line that could be fitted to the need. Pop up a picture and let us see what you are dealing with...

Pretty sure the difference between the two model numbers you posted is shaft length.

Thanks for the help. I'll post pics of it shortly. Since this is just a single wire from the harness and a ground to the engine, from the research I've done, I think this is just an alarm. Not the 3 way that puts the engine into SLOW mode. Is that correct? Also, would the engine be put into any kind of alternate mode from these not working?

I'll try to figure out how to pry the metal limits out and solder to them to see if I can get them working again. Any idead how to pry them out? they are stuffed in there pretty tight and the material the gasket/plug for them was made out of crumbles when you try to touch it with tools.

If your motor is a 1986 model there is no ---S.L.O.W. ----system on it !!----Just an overheat warning.

This will help you decode your model #. And yes, the X is for an extra long length.
