Hi, I was just torn by the wedge ribs…. Normal road trip, battery light went on, sevo set off (as I already knew^^). Still about 1km drove until finally a stop was possible. The engine temp. went very quickly into the red area… turned off and I heard the cool water splashing… ran out at the front right behind the wheel, so directly under the cool water tank. Think that it is still open over an overpressure valve is still pressure on the cooling circuit. Does the water pump run from 3.2v6 also over the wedge ribs? Think it was on the tension roll (marked red on the photo).
