This is what I did with my '11:
Purchased 20 gallons of deionized water from the local Dollar General @ $1/ea.
Purchased 8 gallons of FLEETGUARD ES COMPLEAT EG (Smurf Pee because of the deep blue color) from my local Cummins Central Power shop @ $9/ea
Purchased 2 gallons of FLEETGUARD ES COMPLEAT EG concentrate from the same place @ $15/ea (yes, I could have made 2 premixed gallons for the price of 1 concentrate)
I drained the entire system via lower hose and pulled the thermostat. Filled, ran, drained with water 2 times. Filled, ran and drained a 3rd time but with a gallon of premix included. I did this simply to ensure that IF I didn't get all the old coolant out, at least I had a good base of new coolant. Then I refilled with 1 gallon concentrate and then the 50/50 Fleetguard. Replaced thermostat and "burped" system via coolant vent and filled reservoir with premix.
I over purchased coolant simply for having some extra on hand. I talked to the Cummins tech people and the Cummins Filtration people and everyone was in agreement that switching to an EG coolant wouldn't hurt anything as long as I didn't use it to "top off" my Chrysler OAT coolant. Something about the reaction between the 2 kinds? When my Cummins is involved, I go to the maker of it, not the dealership that simply 'drops' it in the truck. Maybe I'm just crazy.
I have run the 'Smurf Pee' in my system for a year now, no issues. I like the low maintenance intervals, additive acceptance, various inhibitors, etc.
