Thats a picture of the serpentine belt tensioner pulley, so the antifreeze is dripping onto that from possibly the water pump or radiator hose, Use a cooling system pressure tester attached to the radiator and pump it up to the pressure listed on the cap, usually 16 psi, any leak will become apparent real fast! Autozone has a tool loaner program if you don't have it. Then test the cap as shown below.
