Do you change belts only or also tensionsers and pulleys?

W12x · 06-09-2021, 11:41 AM

Time to replaces the belts on my car, first M3 but never really did anything more than just belts on my other cars before, but then again none of my previous cars needed rod bearing replacement either.

Not sure if its worth it to change the tensionsers and pulleys at the same time, car is a MY11 with about 63K.

Any thoughts on this? or anything that I should take care of while I'm doing the belts?

Planning on doing the AC and accessories belts, PS fluid and coolant flush, and BBK/SS lines/rear pads for now. Maybe spark plugs too.
Then suspensions and bushings later this year.

Replace the pulleys and tensioner at the same time. Parts are not expensive and you don't want to do this job twice if you don't need to.

Here's a shopping list for the pulleys:
