I own a 62 ford thunderbird and I took it to a ford dealership. The service manager indicated to me that the radiator fluid wouldnt have to be drained since the intake is high up. From every forum I saw is that the radiator fluid gets drained. Should I call back and indicate to drain the green stuff could I be wrong. What would the possibilites if the fluid would get mixed into the oil. I need a deal explatation on this subject matter. Larry. This is putting in a new gasket on each side and siliconing the front and back.
