Should I flush and switch the Coolent

Newbie Here
After reading posts on coolant issues I can not decide if I should do coolant flushes on a 50,000 mile 6.0
Is it worth the risk of dislodging junk and causing a oil cooler plug up.

Or would it be safer to get a bypass filter and just change the fluid and filter.

The most important thing to do is to get that crappy old coolant out of your engine as soon as you possibly can. It may only have 50K on it, but it is at least 7 years old...
If you want to use just plain distilled water to flush it until that flush water comes out clean, do so.
I strongly suggest replacing it with a CAT EC-1 rated ELC coolant.
If you have an International Truck Dealership nearby, you can use their Fleetrite ELC.
If you don't have an International dealer close, you can use this coolant available at O'reillys autoparts.
You can use any ELC coolant that meets the CAT EC-1 rating.
Absolutely get a coolant filtration on there also.
