I use the Motorcraft link above at least once a month to check for updates to the manuals I've already downloaded. Haven't seen any updates in a while so I think they have gotten them all worked out finally.
Still, great resource to have is the PDF version of the manual. I try to download the PDF manuals for everything I own whether it's dirt bike, bass boat, dishwasher or sprinkler system. Never know when a quick search can turn something up where as a paper manual would require actual reading if necessary.
