  • Cool/Heat: faulty temp sensor

    I believe I have a faulty brand new temp sensor on my 289 the temp gauge starts to climb then It pegs to 240.
    anyone else have this problem?

    Maybe you got a sender for a warning light instead of a gauge.

      I ordered it from SI I have it underlined in the catalog 1957-64 V8 all models.
      I know the work on resistance similar to a gas gauge.
      I just threw away a gauge because it was rusty and crusty, I parted out a rusty 64gt, and recently went from 1380 sq ft of garage to under 500. a lot of things got trashed I posted that I was parting out the car, the only takers I got were two friends her in NC

        Jerry, hey it's too Late to be without your morning Coffee, I think you forgot we are talking about a Temp. Gauge Sender, not an Oil Pressure Sender.
        Because I know you know, that ALL Studebakers have Temp. Gauges, no idiot lights for Temp.

        Mark, could the Orange? Wire to the Sender be bare and grounded somewhere?

        Which Year and Model Stude. is it?

          Check sender voltage, with a thermometer in the manifold my 259 runs at 160-165 however the Gage is pegged, I am fairly sure my sender voltage is incorrect but I haven't changed it. I bought it from a reputable Packard dealer who assured me it was 6 volts. The Studebaker temperature senders are 6 or 12 volts but are different size fittings

            Well, I have seen this problem before with ‘65 - ‘66 Studebaker owners trying to figure out which GM application sender to use. If you check Chevrolet applications you will see different senders listed for gauges vs. warning lights.

              It's a 63 hawk, it starts to rise normally up to about 140 the the next time I look it's pegged. I'll try and wiggle the wire and see if its changes. the seder works with resistance changes, correct? I just put the engine back in this car, the thing that has changed is the sender.

                David (altair) So I guess you are working on a different Car than Mark? Possibly a '54 or older Packard 6 Volt?

                The size of the Stude. Larger senders (12 Volt '56 & early '57) is probably the SAME SIZE as Packard 6 Volt.

                Studebaker changed the 12 Volt Senders to the smaller ones in the middle of '57, so Small & Large 12 Volt DO exist, and the larger ones can be confused with 6 Volt.

                The Voltage change, caused the OHM rating of each to be different. You COULD check it's OHM reading.

                  Thank you Rich good stuff. I am working on a 63 259, I have installed the engine my 54 Champion Sedan. I have kept everything 6 volts. I would therefore be looking for a smaller size 6 volt sender. Question... Would a 12 volt sender cause a 6 volt gage to peg?

                  The engine runs right on 160-162 on my accessory temperature gage and the dash temp gage is pegged. I may see you when I am at the steam gas fair at Berthusen Park

                    Install a Large 6 Volt Temp. Sender on a Late Model Engine

                    I know of NO small size 6 volt Temp. Senders.

                    What you need to do is, install the cylinder Head rear cover plate from a '51 to early 1957 V8 to use the LARGE Size 6 volt Sender.

                      I have a spare 6 volt sender and cover and I will drill and tap it for the larger 6 volt unit, hope it works, thanks.

                          I am going to guess that is with a sensor that is correct to operate on 12 volts being used for a 6 volt system.

                            I don't understand how you got this backwards. Read Post #8 and 10 again.
                            Also, I think Gary may be correct.

                              I was assured from the Packard vendor that the unit was 6 volts, however it had no stampings on it. What is the issue with using a 6 volt sender from a 6 volt system off a 6 cylinder engine and re-tapping the cover plate to suit?
