Serpentine belt
Hello, I have a 6.7 Cummins in an 08 Freightliner. I carry an extra serpentine belt just in case. How long do they normally last based on your (any) experiences. Thank you.

Mine lasted 500,000 miles. If it gets cracks on the top side, change it. If it has cracks on the grooved side, unless there are chunks out of it, don't worry about it.
