There are three 5mm hex head bolts that hold the fan to the clutch. Easy enough to get off but unless you have small hands and some patientce, difficult to get threaded again. Just very small. I did this and found that for me, that it was better to take off the whole fan with clutch intact. If this is your first, it can be hard until you go ahead and make or buy a fan tool which reaches in behind the pulley to hold it stationary, while you remove the 8mm center bolt.
