2002 BMW 330 How to change the alternator?

I could instruct you on the replacement procedure for a donation. The battery will need to be removed from the circuit, remove the air filter assembly. Remove the motor driven fan (it takes special tools and is a left hand thread) remove the fan shroud, pop the caps off the tensioner and deflection pulleys, take the tension off the belt and remove it, remove the bolts that secure the alternator and remove it. Install in reverse of this procedure.
