    Just a general note, the OEMs used to say statistically the number one source of electrical gremlins is connector problems. Grounds more than power connections.

    I got a question, Which terminal does your sending unit have, which is correct and for what years? Threaded or the pin type?
    I think the threaded for the 70.

    All this is great info, but, uhmm,

    WHERE is the Temperature Sending Unit located -arrgg!, sorry.

    I switched to guages and the idiot light sending unit has to go. But I don't know where to find it, to replace it. I checked, my Haynes Useless book of no info, and found no info. Thanks for the help.

    OK I know this topic has gone on forever but please hear me out.
    My sending unit also does some wierd things so with all the talk I decided to change it, one problem I can't find one anyplace. The numbers given in the earlier post were a the pin or nail head type, I need the threaded end type. Anyone know where I can find one of these?? I never figured it would be this hard.
    Bob, by the way Ground Up no longer carrys the GAC-460 anymore he sold all the 300 he had and only has one more he has saved for his car.
    Any help would be appriciated!!!

    Jack,

    Sorry to hear that you cannot find the correct sender unit. I know they are out there, somewhere. Wait a while, one will cross your path. Did you try NAPA? OR give James a call at Moementum.

    Just a side note and I know it is not correct but I believe there is an adapter to be able to use the nail head sender unit to the press type like you have. Just a thought and once again I know it is not correct but at least your temp gauge will work.

    Bob

    Thanks Bob, Still no luck James only shows the nail head type same with Napa. I guess GM discountinued them over a year ago, you would think there would still be some around. Hec I don't even know the GM part number for the Threaded end type. will keep looking got all winter. Maybe I'll try the Swap Sec.
    Thanks Again,
    Jack
