If you do the latter, you will need to take out the engine fan.
Just FYI in case it hasn't been mentioned earlier. You can also turn over the engine by turning the alternator pulley. Removing the cap in the center of the alternator pulley exposes a bolt that is easy to turn. I found that out on this site and used it when I cleaned my intake (manually). Much simpler than removing the fan or using the starter.
