EGR Cooler or head gaskets. My old 6.7 Cummins would blow coolant from the rad cap only under boost. Had a cracked gasket letting combustion gases enter the cooling system.
Pros: coolant blow under boost
Cons: cracked gasket
My old man bought a '22 Limited 2500 with the Cummins and it was the biggest piece of shit ever. We've been a lifelong Dodge family and it was a massive disappointment. The turbo was replaced once at 32,000 miles and then again at 89,000 miles and he traded it in after that.
Cons: repeated failures, poor quality
Mileage: 89000 km
I literally had my cummins thermostat fail and overheat like 6 months ago on a long trip. Popped the housing off. Pulled the core. And drove home without issue.
Cons: failed, overheated
The piston was given to me by a friend who got it from a Dodge dealership. The defect has something to do with the wrist pin, it seems to be stuck partly-pressed in, further in one side than out the other.
Cons: wrist pin stuck
Part number: 3067474
