1998 BMW 750iL Base 12 Cyl 5.40L
Radiator fan blades are all broken. Fan had plenty of clearance.
Radiator Fan suddenly broke all the blades off while I was excelorating.. Why did this happen? What can I do to stop this from happening again?
Replace the broken / faulty engine mounts. The worn / faulty engine mounts will allow the engine to shift position - especially under load / accelerating to cause the cooling fan blades to make contact. Since the radiator and fan shroud is fixed (bolted) to the body - the engine movement due to the worn mounts has caused the radiator fan to break.
