Yes, but, before you do that, how are you going to dispose of the toxic waste? Used coolant is toxic waste afterall. And do you have Cummins approved coolant and not some cheap junk found at the local auto parts store? Cummins is very specific about their coolant so be careful not to use the wrong stuff.
Well two things, Cummins ISB 5.9's use standard Prestone or Zerex anti-freeze. Cummins is a non sleeved engine the block and cylinders are all one piece. Ford and GM both are sleeved engines and require special anti-freeze to prevent cavitation of the cylinders.
I run a 60%/40% mix anti-freeze/water, if you look at the charts this mix gives best corrosion, freezing, and overheating protection.
