If you encounter anyone whose fan clutch came apart (is that better sir ? ) and thinks this is due to the fan clutch's inherent weakness, please ask them to have their engine mounts checked immediately. Fan clutch failure would be a misdiagnosis in this situation. They might change a new fan clutch and have the problem happen again, or install a radiator-mounted electric fan which would not have such issues, but their failed engine mounts may lead to other problems with the car apart from merely increased vibration and noise (feel free to correct me here).

Thank you.


Exacctly my point "Fan Blades" Not the "Fan Clutch"
