I've used the G-05 coolant since purchasing the 95 E300D several years ago. I do add a small bottle of ultraviolet light traceable dye to help find coolant leaks. I check for those about every three months.

This pdf says that G-05 is still ok to use. What is the benefit of changing & what is the latest best?

If your not 100 percent with your hoses might as well change them out to give you some peace of mind. It doesn’t cost much

The best diesel rated coolant is final charge by peak. But G05 works in our small diesels perfectly..

cheap too.
