BMW Engine Fans & Parts for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Older BMWs utilize a mechanical clutch fan from the factory. If your vehicle still has a clutch fan, you can validate its functionality with the 'newspaper test,' but we recommend our customers do a clutch fan delete, adding in an electronic fan to avoid sending a plastic fan blade through your hood. Alternatively, we do offer factory replacement parts for your clutch fan if you would like to keep your vehicle as BMW intended it.

The auxiliary fan in your vehicle serves an extremely important role. When your car reaches temperatures that may be hazardous to your engine, the auxiliary fan moves air through the radiator to provide better cooling. Usually activated during times of stationary vehicle operation, it supplements the air usually driven through the radiator by driving down the road.

If your vehicle is getting too hot during traffic or at stop lights, your auxiliary fans are probably faulty. Replace yours with this piece from Bremmen Parts to restore the factory cooling in your vehicle and prevent catastrophic damage to your engine. Even if your fans are still operational but the blades are damaged or cracked, replacement is the only solution.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF has created a light-weight fan shroud for your E46 race car. Equipped with 7 flaps to let as much air through as possible at speed and fits a 14' fan. Seamlessly attaches to the AAF Radiator Mounts. The shroud creates a vacuum to expand the fan’s ability to pull from the entire surface area of the radiator. This creates cooler temps under the hood with the benefit of 7 flaps that allow the most air to pass through. **AAF states fitment has only been thoroughly tested with their radiator mounts. No fitment info for the stock plastic mounts is available at this time. AAF has created a light-weight fan shroud for your E46 race car.

This fan is driven by the serpentine belt, engaged by the fan clutch. If you have bad motor mounts, it's quite common for the blades of this fan to make contact with the radiator or radiator shroud, essentially self-destructing the fan into many pieces. Be sure to get a new fan clutch, while you are replacing this.
