I would only do it if you have the Natural Aluminum finish version. I would remove the Blastic Parts. You want to use an old Crock Pot, and "KEEP IT AWAY FROM CHILDREN AND ANIMALS." Fill it with undilluted straight antifreeze, put in the engine and turn on the crock pot. You want to make sure that you have a cover on it, with some good ventalation. The next day you can rinse the engine with water, dry it, and relube it.
