    Anyone know where I can get the O-rings or size for the ATF connector that goes into the radiator of my C Class kompressor W203?

    I have bought the replacement green and blue ones from Mercedes in the past and found they still leak
    on W211 and W203 probably due to wear/corrosion on the pipes or radiator sealing surfaces. .

    Feel free to make the repair using OEM you may be ok. 2 x A0289976248

    Mercedes response (and probably MB Independents) was replace the radiator and transmission pipes if the OEM part don't work.

    I use a generic 7x2 O ring from a mixed box slightly thicker than the blue OEM one.

    Please do not bodge this using silicone sealant when reassembling,
    just a light smear of LM grease on the O rings

    The camera perspective makes it look the opposite in the picture though :)

    Thanks. I will also order a mixed box as the price is not much more than ordering just two.

    Five 7x2 o-rings will cost you £2 (via a very good Ebay shop).

    A big box is handy to have, though.
