I'll also point out that this is why we run coolant instead of water in the cooling system. It's got all sorts of corrosion inhibitors in it to prevent even mild steel or cast iron from corroding/rusting.
And, while on a 6.9 you don't generally need to worry about cavitation, I'd still recommend a good HOAT coolant that works fine with old seals like my go-to Zerex HD ELC coolant.
