Replace the radiator fan clutch on a 2001-2005 BMW 325Xi.

Steps

1. Disconnect the battery

   Loosen the 10mm nut on the negative terminal and disconnect it.

2. Remove the air intake duct

   Pry its retaining clips up and lift the duct out.

3. Remove the fan and shroud

   Unplug the electrical connectors, remove the fan's T25 bolt, pry the shroud's push clip free, then use a 32mm fan clutch wrench with an impact gun to break the clutch loose from the engine, spin it off by hand without letting it drop, and lift the fan and shroud out together.

4. Separate the clutch from the fan

   Remove the three 5mm hex bolts joining them and lift the clutch off.

5. Install the new clutch

   Bolt it to the fan with the three 5mm hex bolts, torquing them to about 89 inch-pounds.

6. Reinstall the fan and shroud

   Fit them back in together, thread the fan onto the engine with the 32mm wrench and impact gun, torquing it to about 22-29 ft-lb, then snap the shroud's push clip in and refit the T25 bolt.

7. Reconnect everything

   Plug the two electrical connectors back in, refit the air intake duct and its clips, then reconnect the negative battery terminal.
