I have a 2011 Z4 Sdrive 35IS and the tension bearings failed causing the plastic belt guide to snap and caused the belt to fall off.

Replacing the tensioner seem pretty straight forward as long as I have the correct bits, but I'm not sure how to access the all the pulleys to install the belt. Can anyone provide a diagram and possibly provide the steps? It seems it might be easier to pull the fan and take the bottom cover off in order to install the belts, but I'm not sure if that is the correct approach. Any input would b e greatly appreciated.

Thanks!

I think you’ll get a much better response if you repost this in the E89 forum. This forum is focused on the G29.

On my 2002 M Roadster I take off under body panels to chance the belts, but I don't need to remove the fan.

There should be a diagram of how the belt goes on somewhere under the hood. But you may want to check with the E89 forum as Kwajtrader suggests just to be sure.
