    I just noticed a coolant leak around the radiator connection to upper hose.
    2012
    5.7 V8
    160K with original radiator and hoses.

    Failed radiator cap?
    Worn out clamp?
    time for all new hoses?
    Cracked radiator?

    Its been about a month and I haven't had to add any coolant.

    Probably a tired clamp. But since you’re due - I’d order some mishimoto hoses. They come with new clamps.

    I would disconnect the hose from the radiator and inspect the hose and radiator connection for any damage and if no damage clean the dried coolant and reattach the hose and monitor and see if the issue comes back
