    Usually a coolant leak there is the coolant control solenoid leaking. There is a o-ring kit for it. As for removal, it depends on how munch flailing you have in front of it. And how much crap you have on top of it. All the connections you have to undo are on top of the tank on the sending unit. And they will all have to be undone before you can slide the tank out away from the frame.
