Hello again,
Thank you for your answers and suggestions.
I've already heard and read about the Mulfab radiators.
But I wanted to know whether it is possible to repair this angle piece or if someone has an idea how it can be repaired.
My local dealer already told me to that I would have to change the radiator. But thats the expensive solution.
So if the repair can't be done, I will have to change the radiator but I wanted first to try perhaps another solution.
