I was some-what hoping that the waterpump hadn't gone, anyway top it up and spent about 2 hours topping up and bleeding the system, so far everything has gone OK but will not know untill tomorrow, if the pump has gone, that would explain way there has been presure build up causing the steam, the water has been super heated and escaped as steam. Will see tomorrow if the rad and tank is empty. If so, exspensive :flaming: :flaming: :flaming:
