I was referring to my 15 RAM/CUMMINS. My coolant interval is 150k same with valve adjust.
I also understand being able to easily work on my engine compared to others.
Sorry, when I say "newer" diesels I mean the CP4 diesels, don't know much about Cummins. The official coolant interval per Ford manual is 105K miles I think but people are doing it at 30-50K all in the hope that the engines will last what the old 7.3Ls did. It's become stupid at this point, over maintenance and all but apparently the consensus is that either they work all day every day or if you are a casual pavement princess or low-milage tower, then excess maintenance is in order.... what do I know....
