Accessing the drive belts

[WestEast]

A 2003 320i Auto. Using the Bentley manual, I attempted to change the 2 drive belts, thinking it would be a non-complicated procedure. But never got to the belts. Just couldn't get access to the belts and tensioners, crammed behind the fan. I loosened the fan shroud, but I read that I would have to remove the fan to remove the shroud. I stopped here, as this was rapidly shifting from non-complicated to complicated - for a do-it-yourselfer like me. Any advice on the process ?

It is of great help to remove the airbox to gain access to the tensioner. Also, the tensioners are not behind the fan. YOu may be looking in the worng place. Furthermore, I know for a fact that the Bentley manual points out the WRONG bolt. The tensioner is the one shown in this attached picture with a dust cover on it. You release tension by turning counterclockwise.
Good luck,

Daniel
