I would suggest doing these as 2 separate jobs. Reason being you want the oil hot to change, BUT you want that engine STONE COLD to change the plugs. The aluminum cylinder threads strip/gall very easily. Also, break the plugs loose, then try to remove by hand. If the plug gets tight then reverse and screw in and work back and forth. Carbon on the plug end can also damage the threads. When installing be sure to use a good type anti seize (copper) on plug threads, and torque carefully. Take your time, do not rush this job. Good Luck

edit: just saw the question on safety. The oil is Hot, but is not going to scar immediately. Just have a rag to wipe off. To keep from burning fingers on the hot drain plug I recommend using the allen wrench to unscrew the plug. This way you keep upward pressure up against the case and when you feel the threads jump as it is completely loose just tilt and pull the wrench toward you. You control the drain and don't lose the plug in the drain pan, that can plug the drain holes. Thanks CoBeertoad.
