Also remove your fan clutch and use a cherry picker on the hook over the water pump so the front of the engine doesn't come down and puts unnesscessary strain on your motor mounts.

If you go to a forum like DTM power or Pelican or BimmerForums or UnitedBimmerCommunity and search, you will find the instructions. I would rather not tell you how because I would feel guilty if you made a mistake and flame-broiled some very expensive electronics on your car.
