    Default 504 water pump

    Hi, the water pump on recently acquired 504 wagon is now leaking at a good rate, have located a replacement. looks fairly straightforward to remove and swap in the new one, but does anyone have any tips/tricks/things to watch out for etc.

    Getting the old one off will be the challenge.
    The inset into the head tends to coorode itself in, also the studs tend to coorode inside the pump body. With these two adhesion problems the pump can be VERY DIFFICULT TO REMOVE. Give yourself plenty of time and make sure you have plenty of cold ones on hand to cool the frustration.
    Good luck

    I recommend that before you fit the new pump that you file out the hole in the head slightly (say 0.5mm) where this inset fits, to give a little more clearance. In my experience there is no downside to this and it makes it much easier to remove the pump next time.

    last time i did a water pump i took the ten minutes to remove the radiator, its so easy and it makes the pump easy to get to. you can almost throw the pump on to the engine from across the shed...lol...other then that, easy job. yes, it can be a pain getting the old one off, but a gentle pump with a block of wood normal gets it going.

    Thanks guys, am due to pick up a replacement pump tomorrow to do the job over the weekend. Just as well I've picked up a couple dozen Macs to ensure everything gets well lubricated...
