Do a search, once you see how its done its incredibly easy. there is a hole in the back of the pulley hub and a groove in the housing. line them up, put a strong pin in there to hold position, put a cheater on your front Allen wrench and its off. My special tool was an allen wrench with the short arm ground down shorter, long arm taped to a long screwdriver. Now it takes longer to R&R the fan shroud than the clutch
