    EGR valve. Is it one of the quick connect fittings on earlier model?

    EGR valve is pricey. Take a picture of leak.

    You should just need new o-rings on the two coolant tubes.

    Hi, I have 2016 t680 with mx13 epa 13 700k miles. I get warning lights and stop engine lights on with low coolant when on down hill and flat ground. When pulling grades or truck has to work a little then all lights go away. Coolant tank has exceeding pressure in it. Truck runs normal not over heating at all with 80k in box. Any ideas . TIA.
