Anyone replace a pusher fan? I removed the
 

front bumper, disconnected PDC, fog lamps and washer hose but couldn't figure out what to remove next. Is there a DIY somewhere or a useful thread? I tried searching for pusher, aux, auxiliary fan but didn't find anything. My pusher fan stopped working, so I bought a new one to replace the old that was diagnosed as needing replacement.

2001 X5 4.4i

Are you sure it was the aux fan which failed? It could also be the aux fan control switch. By the way there was a recall on the aux fan issue. See below:
Good luck

Here is what I found for testing/replacing the aux fan for the e38 with the same engine as your X5 4.4. The process will be very similar.

Thanks everyone; I'll check on the recall issue and go
 

from there. I'll ask a BMW technician and speak to BMWNA.
