What would be recommended to fill water antifreeze reservoir when low? Water,50/50, or straight antifreeze? If straight what kind/brand ?

If it is your plastic overflow reservoir, I would simply add distilled water if you are confident that your coolant is in good shape.

Otherwise a 50/50 mix of distilled water and low silicate coolant that is meets the Cummins specifications.

As I think you have the 5.9 liter Cummins, you do not have to worry about SCA's.

X2 what Dave said..Mine has a strong enough mix of anti-freeze so I just add distilled water...but..I don't have to add very often.

I use the 50/50 mix also. I keep a gallon container of it in the tool bay (the last bay on the co-pilot side)of my 97 Discovery.
