    Can´t seem to find where it´s coming from. Left side of the motor is covered in white residue and it loses water when it gets hot. Not coming from the filler cap as it´s on the right hand side, and no obvious source of leakage. Has anyone come across this ... and found an answer?

    My 610 had a similar problem three times. Until the guarantee was valid, I brought it to dealers. The first times they replaced a hose and the second time the leak disappeared when they removed and reinstalled the hoses.
    The third time the leak was this:

    I understood that the coolant came from here:

    It was almost invisible:

    I smoothed this surface using sandpaper:

    and since then it hasn't happened anymore.

    HOSES! Now why didn´t I concentrate on them? Thanks for the info, the hoses are all I´ve got left to inspect.
