    I was told to flash the coolant first to see if that solves the issue I was going to try that before I spent $1300-$1600 For a metal hose issue where the EGR actuator is not a problem to see if that fixes the back pressure problem if not definitely will take that Under advisement thanks just trying to see if anybody else has the same issue

    are you sure metal hose is leaking and not the adapter that goes between metal hose and actuator body ? there is a o ring that goes between actuator body and connector adapter.

    Add a radiator stop leak it will stop. Works good in the summer never leaks until winter. It leaking inside your egr. There's like a small heater coil inside that's leaks when it goes bad.

    there is no heater coil inside. I have opened them. if you will open upper or lower covers you will see the coolant flows through body..
