Temp Sender Unit???

[Deleted User]

I can not find the tempurature sending unit in the Service Manual or the Parts Manual (I know it is in the Part Manual somewhere, Electrical Section, I think).



A search of this forum would indicate it is on the back of the block.



That being the case, what is the item in the picture below? It is located driver's side and in the head at cylinder 2. I am the one who covered the bar wire with electrical tape.

Hi Pace,

Thats it in your photo.

You might want to focus on replacing the frayed wiring first.

The tempurature sending unit is found in the Parts Manual in the Engine section (H) page 73 under H3-17. The gauge test is found in the Body Service Manual page 51.

Thank you. I looked there as well buy obviously missed it. I am guessing since the plates on show the passenger side of the engine, it will not show the unit.



.......OK, found them......However, the Proceudre manual states it in the read (firewall end). Why no note to mention the 232 is up front?

Funny!! I was thinking that might be the brake light switch or reverse gear sensor.:)



I find it interesting that the 232 has it up front and other engines have it in back (per the Cooling Issue threads here and Procedures Manual).



I wonder why the design change?

The wiring actually seemed good. The old covering was bare at the end but no strands were broken. So I just taped it up. A complete re-wire will come next year (I think).



One thing I do not like about the Master Parts list is that they do not show every thing and they do not show the drivers side of the engine. I am a visual learner. I look at the engine (or what ever I am working on), then I look at the book to see how it is put together and what that parts are that make the assembly.

I liked the muffler bearing.....



ever ask an autoparts store for a waterpump for a 68 volkswagen?



as for the wiring, do yourself or any possible passengers a favor, either replace the entire harness, or rewire anything that looks that bad, and that one looked bad. You can easily buy the proper guage wire, in the correct colors, and doing a neat job and correctly is pretty straightforward.

I was thinking was too small to be the differential housing......:)



I will get the wiring done. I traced this back to the firewall gommet and the only issues was the two spots where the laquered cloth had become brittle. One other spot broke as I moved the wire, so it is taped. I do have a new battery to starter cable that will go on once the starter and generator come back from service and cleaning. The OEM that is in there now does have some frayed strands at the battery terminal.

Hudson kid is right, safety first. Don't risk short-circuiting, fire or component damage due to bad wiring. If what you can see (jacket/insulator) is bad, the old wiring within it is probably corroded. Since corrosion increases resistance and, in doing so, creates heat, the old insulation (rubber and cotton) can ignite. Not to forget that an increase in resistance will impede how things are supposed to work. Installing new components on a car with an expended wiring system is like installing a new furnace in a home which has rotten ducts. Smokey says: "Only you can prevent Hudson fires."

The reason for the confusion is that the '48 to '50 engines had the temperature sender located in the front, while '51 and later engines had it located in the rear. Why the change? The earlier engines had it located in the front to clear the Drive-Master installation. In '51 Hudson went to the Hydramatic and moved the temperature sender to the rear to simplify the wiring. Note. In '51 Hudson also changed the gauge type and sender.
