Just bought great car but it pushes water out when stopped hot :thumbsdown:, radiator and engine hold water normally and when running. When I go to fill the expansion tank coolant runs out on ground, I guess that's why it loses water. Any clues?
Expansion tank info >>> If overfull/overfilled it will leak from the neck to bottle joint. Check dipstick has coolant up the mark. If not holding coolant at all, maybe damaged as Tekky stated. Is the rad always FULL, when checked cold?
