My Ride: '02 330i 6MT
DIY: Aux/mechanical fan to electric fan swap

All you need is is this:

floor jack and one jack stand
philips screwdriver
I think Torx 20 head
8" extension
ratchet
8mm socket or 8mm wrench
9mm socket
13mm socket
fan clutch tools
OEM electric fan: 17117561757
Expanding rivets: 51718229003 (4)
51118174185 (as many as your break)
51471919209 (as many as your break)


- Jack up one side of car (I did the drivers side) and put one jack on the metal plate
- Remove the 8mm bolts holding bumper to the fender liners
- Take out the reinforcement bolts with 9mm socket/ratchet/extension
- Slide bumper out (unclip wiring for fogs and horn)
- Take out the top air intake
- The center duct is held by four pop in screws
- Aux fan is held by four 13mm nuts, take them out
- Disconnect the aux fan by the fan shroud in the engine bay
- Slide the fan out
- Put the center duct back in and top air intake
- Put the front bumper back on in reverse order (slide in, put in the two reinforcement bar bolts and the assorted bolts to the liners.
- Next you have to take the mechanical fan out
- Pop out the fan control unit on the shroud and the other wiring and put them to the side
- Take out the 1 torx screw on the passenger side top and loosen up the fan shroud
- Use the fan clutch tool to loosen the bolt and take out the assembly
- Take your electric fan and slide it against the radiator and screw in the torx screw
- Plug the electric fan to the connector where the aux fan was plugged into
- Place back the control unit and the other wiring to the electric fan shroud

Viola, you're done.
