Moin, as briefly described herehttps://www.motor-talk.de/…/…at-or-was-others-t5075597.html?… I have ruined the cooling water connection of the DSG oil cooler at Passat B7 due to stupidity. They are unround and I prefer to buy a new one. Soo exactly I get the only with patience round again or not at all. “Previously” I have fixed/- sticky cooling water hoses (here diameter approx. 2cm, sit almost 8 years firmly) either round-side running down with a screwdriver If or when it was possible, a screwdriver carefully extended something. Both did not work here, so, like “formerly” also , I carefully tried to rotate the hose at the circumference on the stun. In doing so, the stun moved at really only medium scraping effort itself and I left it immediately . Only at this time I had pressed the stun in diameter already slightly oval and at overpressure one to five thin coolant jets out 🙁 With solc I didn’t count for the trumpet sheet: So there used to be no such thing!!! 🙂 How do you correctly remove such hoses from the sockets nowadays?
