It seems that you really know your stuff. I will need to replace the fluid lost while replacing the radiator and I want to just put the right amount in and drive the car before I do a fluid and filter change. What fluid should I use? Should I just go with the valvoline max life or will it not mix with what is in there already? I also need to put the lines back on the radiator, but I can't seem to find the copper washer size or where they need to go. I seem to recall one of the lines had one and the other did not.
