I have a customer traveling a substantial distance for me to work on his truck, which he suspects is needing an EGR cooler and possibly head gaskets at this point. His local dealer has been feeding him poop for quite some time now and he is getting rather upset with it. They have repeatedly attempted to address his degas bottle blowing coolant out of it under load, and failed every time, he tells me.
I pull a warranty history on this truck, and see this as the last warranty repair.
