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.

I'd go ahead and replace it for the reason Ivylog stated, especially if you can do it yourself. I just replaced the belt on my daily driver at 7 years 160k miles. The old belt showed no signs of wear or cracking.
