[urq] Alternator Whine and Airflow Direction

[Ingo Rautenberg]

Oh Boy!  Too much coffee or not enough, Ed?  ;-)

Since the alternator is facing the same direction (forward) and the engine
is turning the same way (I think the AAN / 3B motors turn the same as the
regular I-5 motors), location of the alternator will make no difference on
rotation of the cooling blades.  However, I'm not sure if the 4kq blades
serve to suck out the air like the urq one does.  Maybe the 4kq one pushes
the air instead?
