Hi all. Newbie here looking for help. I'm going nuts over this..,and wondering if anyone might be able to shed some light. I am trying to drain the coolant from my 2010 300c,and I can't find ANYWHERE if there is an engine block drain plug. I've opened the radiator drain and disconnected the bottom hose,but I'm not 100% sure it's all draining. Any help please? Olly
