Hi All, This is my first post, so big hi to everyone. I have an OBD1, 95N VR6, 95K Highline that I have had for a number of years. Problem is that the coolant level is going down rather quickly. I haven't measured the amount exactly but it is quite considerable, say 250ml every 20 miles. I have replaced the Aux water pump, thermostat housing, radiator and a number of hose clips (to jubilees). I have now noticed some steaming up inside which I presume is the Heater Matrix. Problem is that I think that I am fixing the symptoms and not the cause. I have pressure tested the coolant overflow to 1 B
