[s-cars] fan clutch replacement

[Mark Strangways]

The clutch on mine is seized like a wife on a wallet, (can't wait to hear 
about that crack)... and at high rpm the whole fans grows due to 
centrifugals to a scary level.
It looks like it's gonna take off already. So it must go. If I am gonna 
break a motor it will not be because of a grenading fan ;-)
