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.

We had ours replaced on our previous coach at 6 yrs. old and 50,000 miles (8.9 Cummins 425 ISL). The belt was showing cracks on the underside (top looked good).
