Might be a dumb question but couldn’t find much on it so I’ll ask. (2013 6.2) My upper radiator hose needs replaced. Lower still looks fine. Very tutorial I’ve seen recommends draining the coolant before you do this, but most are replacing both hoses. In my case I’m just doing the upper, and I can’t imagine I’ll lose too much fluid swapping the hose, so is draining the radiator necessary? Also if I do need to top off, is any parts store orange 50/50 coolant ok or does it have to be motorcraft?
