Mike, don't remove the fan clutch, just the fan blade assy and shroud (optional, if you want really good access). The crank seal will require removing the radiator and the harmonic damper. You will need a special tool to hold the damper whilst loosening the retainer bolt. (check with parts shop here). The rest is metric sockets, allens and wrenches. Good luck.
