    My 1993 240 had a new water pump 4 years and 20,000 miles ago. I'm
    losing coolant fluid.

    I though water pump would last easily 5+ years.

    Your opinion is greatly appreciated. Should I look elsewhere? The
    lost of coolant is very slow. Should I go for a pump change or ???

    is the leak from the pump shaft seal, or from the rubber gasket(s) that mate
    with the engine block? About a year ago, I replaced the pump and gaskets on
    my '89 240, not knowing that the rubber gaskets are known to fail, and can
    be replaced without replacing the pump itself. I kept the old pump as a
    spare, just in case, and could have saved myself a little money had I known!
    on the other hand, if the leak is from where the shaft enters the pump body,
    it's the pump seal itself, and you need to replace it all....

    If your water pump is leaking it needs to be replaced. It doen't matter
    how old it is. If you can see a trail of greenish dripping from behind
    the fan, running down the front of the motor, it could be from the pump.
    If there is no dripping, you need to look elsewhere, like all the hose
    connections, or maybe the radiator.

    It could be leaking out of the round rubber dounut seal on the top of
    the pump, where it seals the head inlet.
    I have had that seal leak from time to time, for years.
    I have replaced many good water pumps only to need the one top seal.
    Not part of the pump, while, kinda, part.

    What I do, now, is just let it leak.
    When the engine heats up the leak stops.

    I may add a pint of coolant a month and I watch it carefully.

    I know that many of you guys would never have a B230FT with a water
    pump that leaked,
    after you put it in.
    I check the bearing weep hole, If it leaks there, I replace the pump.

    Changing the water pump is a good time to do other maintenance thingy.

    Not hard to do, just takes time.
    Nice Spring thing to do.

    Thanks all for the info. I had "forgotten" to look for the
    bueish-greenish liquid. Will sure do.
