Do all new diesels need this test every 15,000? What about new gas engine trucks? The radiator fluid in our 2003 Dodge needs to be changed every 100,000 miles.
I don't think so, gas not sure and yes 100k miles or 5 years is Cummins PM rate.
"Why the big difference?" Google Ford radiators. They've had a few problems to put it lightly. That is exactly why I stated to have it documented by Ford dealer.
The Cummins have always been easy with coolant, the reason is the block is solid one piece cast iron. Ford and Dmax use separate cylinder liners. You can have issues with cavitation, which is when small bubbles form on the liners and erode them.
