Hello, Since I did not find anything suitable about the SuFu, I open a new topic: It is a S70 T5, EZ. 1997, 166tkm Today I discovered a small puddle on the cooling water holder, it has not yet dripped down. The coolant comes from the hose connection front. The hose leads from the container to the large cooling water hose. Under the part number this was called “Bleeding pants”. I am already aware that here no one can provide remote diagnostics Maybe someone had the same problem and knows what that might be. It will be either a clamp, hose or the container. I would start with the clamp, are they suitable here? https://amzn.eu/d/cVI2eeN I would get the cooler hose via Skandix. Thanks in advance!
