I'm sure there is a flush for the system, But if it clean ? I would just drain it and refill with the same, If it's original and your over the life of the coolant, which it sounds like you are.
You can also test it to see if it's up to snuff, with a test strip of paper that changes color depending on the condition of the coolant.
If it was me, I would just change it out so I knew where I was at.
They hold alot of coolant (10gal ? ) so for my money it's worth having it done so you don't have to deal with the old coolant.
I consider the cooling system on diesel trucks as important, if not more so, as keeping good oil in the engine.
And yes it looks kind of pink in color.
Just to add, I'm not sure if the ELC coolant comes pre-mixed or not with water ?
So if you have it change by a shop, find out the system capacity and the right amount of distilled water you will need if it's not pre-mixed.
Then you can pick up the distilled water at a market or ? so the shop doesn't ad regular water like many will. The cost of the D water is so cheap but way better than tap water for the system.
