Question about 2004 Scion xB
Bottom bolt on the alternator is a 14. Top two are 12. You will most likely need a breaker bar to get the bottom bold lose. Be careful. I stripped my bottom bolt trying to replace my alternator.

There is a bolt on the bottom of the alt that holds it.
You should be able to use a 3/8" or 1/2" ratchet with a 12mm socket. (I only felt it, so I am guessing)
But 12mm seems to be a very common size for Scion and Toyota in general.
The bolt goes through two ears (or lobes) that are part of the engine block. The lobes are on either side of a "tunnel" that is part of the alt's housing. If it is too difficult, try shooting some penetrating oil into the back, where the threads are set into the lobe on the block.
Careful not to spray any into the alt itself.
