3rd Gen Cummins requires the HOAT coolant. Yes, use distilled water.
True. Isn't a bigger concern with a flush/refill, especially with HOAT or OAT anti-freeze is making sure the refill introduces as little air into the cooling system as possible? Was reading that even the "overflow" bottle on the new Rams was part of the pressurized coolant system now.
The first time I had a coolant flush/refill done on my Ram, the tech. hooked it up to something that looked like a kidney dialysis machine.
