That junction you claim is mis-aligned has an intermediate bushing with seals. Those seals can go bad, and if someone did a poor job of replacing the EGR cooler, and didn't replace the bushings, then that could cause it to leak.

If your coolant is not getting to 185 degrees and consistently staying there then you likely have a bad thermostat. This can cause a LOT of engine problems including head gasket issues.

Lastly, Condensation likes to build up in the intake pipe you say coolant is coming from. Don't mistake condensation with coolant. Find out for sure what it is, and if it is coolant, then the insides of the pipe will be soaked with it. - As well, you should NOT have any kind of leak there at all, coolant, air or otherwise. A leak in the EGR mixing pipe will lower fuel mileage just as bad as a charge air cooler leak, but only worse.

I've removed clamps from that rubber pipe and black liquid come out
Tomorrow have to deliver load and after that I will try to remove cooler and check it for leaks
