    1980 Volvo 240 Radiator, connectors and fluid capacity

    I want to remove/replace the radiator of my 1980 Volvo DL. I found
    that it is relatively easy to take out the radiator, except for the
    two thin metal lines connecting to it (see images
    http://www.alexandria.ucsb.edu/~rnott/tmp/Volvo240_radiatorLinesDetail.JPG
    and
    http://www.alexandria.ucsb.edu/~rnott/tmp/Volvo240_radiatorLines.JPG
    ).

    My questions are:

    1)
    I have trouble loosening the connections of the two metal (aluminum?)
    lines going to the radiator, the ones above and below the thick rubber
    hose. Is it just a matter of applying brute force or more WD40? (I
    don't want to break off or damage the lines, though). What is the
    function of those metal lines, anyway?

    2) What is the colling fluid (antifreeze) capacity of the radiator?
    And does that include the air conditioner fluid (the air conditioner
    sits in front of the radiator). I don't want to drain the radiator
    before I buy enough fluid to refill it.

    Thanks for any information.

    P.S.: I've the Haynes "Volvo 240 Series Owners Workshop Manual 1984
    edition", and I find in nearly useless. Any recommendations for what
    better manual I could buy (Or links on the net)?

  2. These lines are the cooling circuit for the gearbox. Inside the
    radiator is a copper vessel that these two pipes connect to, and the
    transmission fluid runs through. This is in turn immersed in the water
    of the radiator, so it all tends to run at the same temperature.

    The connectors are collar nuts, so the pipe doesn't turn when the nut
    is turned. Grip the brass part (that is attached to the radiator) with
    a close fitting spanner, or if it is very tight, vice grips, and then
    use another spanner to apply force to the collar nut to undo it. You
    may lose a little oil from the lower one; make sure you replace it
    with new into the gearbox dipstick hole.
    IIRC the capacity is about 2 gallons (UK measure - 20 fl oz = 1 pint);
    the mix of antifreeze with water will vary depending upon your local
    climate - it should tell you on the can. The AC is a separate system.
