F250 Powerstroke 6.0 I made a mistake trying to replace the oil cooler.

Hi guys. I am new to this site. Today i was trying to replace the oil cooler and i wanted to flush the coolant system. Stupid me , i flushed the system before i mounted the the oil cooler housing and about two or three gallons of water/ coolant went thorough the hole under the screen in the reservoir where the hole is for the HPOP. ( not the turbo drain valve or ipr screen)
Now my question is what should I do next? Do i have any coolant left where it is not supposed to be?
I drained the oil from the oil pan, and blew air with shop vac through the little hole, and through the oil drain valve for the turbo.
Any suggestions highly appreciated.

P/S : I used the picture as a reference to show the hole where i got the water through. Yellow circles where the water went in. The picture i used is not my truck.

Thanks a million.

I would pull the hpop to make sure any water in that passage is out. Once you pull it off, it will leak the oil cooler resevoir out, back down to the oil pan. Maybe run some brake cleaner thru it too.
