just follow the serpentine belt, by necessity, it has to rotate the pump. Serpentine hits water pump, a/c compressor, alternator and steering pump. Steering pump is the smallest of them all, and the only one that has a filler cap on top.

What does a diagnostic tool mean when saying "bank 1"...

It usually means the catalytic converter is not getting hot enough to function, but could be another issue. The sensor readings between the sensor before and the sensor after the cat are not within spec.
Bank one is the side with cylinder one, or the side with the catalytic converter.

The error that I'm showing for error code P1133 is 
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank).  I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done.  Hope this helps.  Thanks for an honest rating and for using FixYa.
