EGR cooler bad????

    Hi everyone!
I'm just driving second week on my recently purchased 2011 Prostar with ISX. Right away after I got it i did EGR tune up, pipes was clean no soot collected. Coolant pressure test system for 30 min and lose no pressure. First week my coolant temp won't go up stay around 140-150 but second week temp normalize and track start consume a lot of coolant. I'm noticed wet spot on rubber pipe(shown on the picture), then I did coolant pressure test again and found leak where EGR cooler pipe meet engine block pipe. That's hard to see from picture but there is misalignment.
Now I don't know what to do. Do I need order new EGR cooler or just alignment properly old one?
