Blown EGR cooler usually puts water in the cylinders and causes the engine to hydrolock if it sits for a while. There's generally not enough pressure in the exhaust system to pressurize the cooling system, and certainly not at idle.
I've seen 3 fail on tractors that did none of that, just pressurized the cooling system and pushed coolant out.
Being it's an ISX I would think liner and head gasket, but I was trying not to be a Debbie Downer and going to worst case first. Cummins are pretty throwaway these days.
