Radiator hose
Want to eliminate this “mod” from the previous owner. Coolant has been leaking from it. I’m replacing the radiator this weekend and wanted to take that brass fitting out. Pretty sure someone here has a better option that what was done.

See attached, but take off the clamp that is circled in red and use the new cap with a clamp at that location. Since you have leaks occurring, I would not re-use those clamps, but rather use a new clamp. Good luck and welcome to he forum.
