This is a DIY on how to replace a power steering pump on a 2000 Infiniti I30 
This photo above will show you how to loosen the serpentine belt for the power steering because there are two belt tensioner one is on the power steering pump the other is for the A/C and alternator - There is a top bolt that you have to loosen first that is holding the power steering pump - Then underneath it will be the adjuster 
The first thing to do is to remove the power steering hose pressure and non pressure hose 
This bolt can be a pain in the butt to break loose but its up towards the top the diagram will help you locate it - But this must be loosen before you can take the belt off 
Then to take off the pulley 
For the new pump to fit you have to push back that slider pin 
Power steering pump Auto Zone part number AAE5233
This is the power steering belt 
This is the adjuster bolt for the power steering pump
Adjusting the tension on the belt 
Put everything back the way you took it off - This is a difficult job and you must have patients cause it is tight in that area - Bolts can be on tight and you have to make sure before you can adjust it you have to have the top of the pump bolt loose and the adjuster sleeve loose you might need to bang on it to free the pump to swivel
