Serpentine (Drive) Belt Replacement

pmsteinm · 03-09-2024, 11:06 AM

Does anyone know what the expected service life of the drive belts are these days? ISTA didn't have any interval information and changing it looks like a royal PITA so not worth it unless you are in there for something else.

I remember on the E90 w/N54 that the belt would start making noise like clockwork around 50k miles.

My 2018 has 53k and the belt looks great. I was just looking at it while installing the Dinan intake and wondering about the replacement interval. Maybe I’ll change it at 60k.
