Many components from your BMW's cooling system are prone to failure - including the stock fan blade. If you've had the unfortunate experience of dealing with a broken BMW fan blade, we have you covered for replacements.
This fan is driven by the 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 peices. Be sure to get a new fan clutch, while you are replacing this.
