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.

Replaced mine after 7+ years, just cause. Still looked new and was fine as per my wear gauge. Kept it as a spare.
That's the way I done it and now have a spare that I know will fit.
For the OP, most quality belts will deteriorate from age before they wear out with mileage.
