norbury.brook Posted February 6, 2025 Share Posted February 6, 2025 I have just completed the front bearing installation. I started the vehicle with the hood up, and when shutting it off, I noticed the fan emitting a growling noise while decelerating. There is considerable play in the fan. Is it sufficiently clear for replacement? Would an Andante chance for a 320d constitute a straight exchange? I own one already. Your guidance is once again valued!

SD1too Posted February 6, 2025 Share Posted February 6, 2025 Typically, BMW fans may be easily replaced by simply detaching a few clips or fasteners and removing them. The fans for petrol and diesel engines are distinct on realoem.com; thus, I conclude that it is not a straight replacement. Quote Link to comment Share on other sites More sharing options...
norbury.brook Posted February 6, 2025 Author Share Posted February 6, 2025 Thank you for that information. I will attempt to locate a tutorial video. Both vehicles are diesel; the 320d from which I removed several components, and my current vehicle, the 330d. I will be able to compare after the old one is removed. Thank you one again.

SD1too Posted February 6, 2025 Share Posted February 6, 2025 You may ascertain the appropriate component number by entering your VIN on realoem.com. Quote Link to comment Share on other sites More sharing options...
norbury.brook Posted February 6, 2025 Author Share Posted February 6, 2025 I seem to own the variant that is affixed to the water pump. I will do more investigation. Thank you, I will. Quote Link to comment Share on other sites More sharing options...
norbury.brook Posted February 6, 2025 Author Share Posted February 6, 2025 I own a viscous clutch-driven fan connected to the water pump. I am uncertain if the issue is inside the plastic fan or the clutch component. Removal is necessary for observation. Any insights about these kind of fans would be welcomed! I have ordered a locking tool and a spanner, and I understand that it is undone by turning clockwise; that is the extent of my knowledge.

Ken_Lion Posted February 6, 2025 Share Posted February 6, 2025 In this instance, it is necessary to replace the water pump. Quote Link to comment Share on other sites More sharing options...
norbury.brook Posted February 6, 2025 Author Share Posted February 6, 2025 Thank you for that. Could you elaborate? Is it not feasible to detach the fan from the water pump for whatever reason? Quote Link to comment Share on other sites More sharing options...
Flexfer Posted February 6, 2025 Share Posted February 6, 2025 I would remove the fan and juxtapose it with the one from the 2-liter diesel you own. Quote Link to comment Share on other sites More sharing options...
norbury.brook Posted February 6, 2025 Author Share Posted February 6, 2025 Regrettably, I own just the housing, not the fan. The clutch seems to be sold separately from the fan upon purchase.I must remove the old component to see if the issue is with the clutch or the fan itself.
