I have to consisit put water in my radiatior,the water won't stay in it,but in my reserve it's fine. I have change the sensors,the belts and hoses,the water pump,I have put something in my raditor to help seal up a head gasket,the only reason why I put that in is because I was told it was a blown head gasket.If I drive for a long time it will start running really hot and the water in the reserve will start boiling. I dont' have water in my oil so that has me thinking that it's not a head gasket blown. I really don't know what to think. I need help.
