Changing the Power Steering Pump

Sport Sidekick - 1.8 L DOHC 4WD - 112,000 miles.

I have to change the PS Pump - bearing going out.

Bought a used one for $40. 3 month warantee. Wrecking yard.

The Beloved Chilton Manual says to take out the radiator fluid reservoir and Oil Filter
before removing the PS Pump ! p 8-38 to 8-39 (#66500 Book)

What in God's name for!?

And where is the PS Fluid Bleeder valve the Chilton mentions, but doesn't show
or explain the location of....?
