  • Radiator pipe

    When it rains it pours

    went out this morning to find a leak dripping from bottom of radiator.

    doesnt seem to be coolant it seem to be 2 extra pipes coming from the bottom of radiator.

    it was dripping what appeared to be water.
    the elbow fitting appears to be loose which I was able to just pull out, looks
    like thread may have gone and has been bodged up at some point.

    when I removed it I got a red looking oil coming out but not much.

    im a bit baffled

    cant find any pics in book showing this pipe on radiator.

    any ideas

    thanks for your time

    Auto transmission oil perchance?
    You could bypass it with a double ended barb joiner temporarily, but in the end the rad will need replacing.

      The heat exchanger in the bottom tank is a pretty crude affair.
      I’d try to tighten the fitting (gently) to ensure it isn’t just leaking on the flare.

        So I can just join the 2 pipes together and it will be ok??

        just while I sus out a new radiator??

        should there be much oil coming out??
        it appeared to be dripping water and oil.

          We can’t advise on that one Tony, transmission oil temp will get very high without the cooler. You might sit in traffic and cook the poor thing.

            Been raining so I chopped up my old 90 radiator for you.
            This is a Toyota radiator so the oil cooler pipes are silver soldered to the cooler fitting.
            If yours is like this and the pipe pulled out...... she's buggered.
            Aftermarket radiator will have a flare fitting to the cooler.
            So you'll see that large hex nut which holds the cooler to the bottom tank, and then in front of it you'll see a smaller hex nut which is the flare nut for the pipe.
            The flare nut can be loosened and then the fitting orientated in any direction.
            A loose flare nut will leak transmission oil.

              Thanks for the help and info.

              i had to do the joining the hoses together as a temp fix. The wife needs the car for work at night so at least it’s a bit cooler then.

              yes it is as your pics and yes it is buggered.
              even looks like it was glued in possibly by previous owner.

              i ordered a new radiator so hope it arrives soon.

              thanks for your time

              very helpful
