    Can you post another pic or two maybe a little further out away from that? It might help someone who is looking and trying to help you with determining what it is called.

    as soon as i get stopped ill get under there if there is enough light with a flash light to look, its the round piece in between the two hoses where you see a drop of coolant leaking from, the hose runs along the passenger side rail underneath the cab

    It is a new part for 2023 related to the DEF Q sensor failure issues. Let me see what I can dig up for part numbers for you. It will be Paccar dealers only.
