    Default Normal frequency of top-off for cooling system

    How often do you guys top-off the cooling system with water. I add about 1 quart of water every 2-4 weeks.

    Thanks

    I add about a quart every month or month and a half.

    Before my waterpump went I'd top up every 10000km. Now it's holding.

    By the way there was a recall on the resevoir cap of some e34's due to it leaking or something - still stands so if you take it to the dealer they can check if yours needed it and whether it has been changed. If not its a new one for free. Worth a check.

    leaky heater core, leaky expansion tank ~1qt / month
    now my radiator is seeping at the seams. So I'll fix the expansion leak in a few days, pop on new hoses but the heater core will have to wait until next year when the weather warms up.

    Been looking at the hoses and it appears there has been some weeping of coolant at some time (currently?) where they clamp to the various spots.
    Were hoses 1 and 8 difficult? They both pass under the intake manfold. There is a clamp (16) that looks like a pain.
    Also loos like some weeping past the thermostat housing and gasket. That looks preety straight forword.

    TIA

    Jim

    And I will check out the expansion tank cap.

    Actually, it was for pretty much every car produced during the era. I've always been told that its sole purpose was to mine data on owners -- nothing particularly wrong with the original caps.

    Never needs top up since I replaced heater valves, aux water pump, radiator and most heater hoses. Also good quality new hose clamps of course
