I have an Astra J 1.4 turbo which the other week I knocked a hose off which is held on with a little plastic clip and radiator coolant was pumping out like a fountain (as car engine was running). It is the hose that T off another hose and leads to the expansion tank (smaller pipe), as I said the T hose is held on with a little plastic clip. [Image:
