& you should invest some money in a smaller pulley to reduce the fan speed. The original 175mm is way too big for 5000 revs.
usually for more than 4000 you need a smaller one, I would go at least to a 146mm.
and don't worry about the cooling this will not be affected or even better because the stock fan can't handle the high revs anyway.
And check the alternator before you reassemble, usualy after a fan crash it's not in line anymore and ready for the trashcan
I just can say it again also if nobody replied to my post.
with more than 5000 rpms a smaller pulley for the engine builder here in germany is absolut standard to prevent such fan crashes.
