It looks like the radiator outlet hose. Look for 'Mopar #68104977AC' or equivalent. Maybe not normally stocked at auto parts stores due to its complexity. Google it. Call some dealer parts depts. Dorman might make one?
Are you sure that's not leaking from the plastic connector piece, at the end of the right side of that hose in your picture? Mine completely cracked and blew off. Turns out they completely eliminated that plastic connector piece, and changed to a solid metal pipe from that point on to the thermostat. Just used a band clamp to connect to that rubber upper radiator hose and it's been fine since. Dealer only part as well.So I found out where my coolant is leaking on my 2015 Chrysler 200s 3.6l but I’m having trouble finding this hose. Can anyone tell me what this hose is called View attachment 59104
