Installation is the reverse of the removal procedure. Tighten the pump mounting bolts to 18 ft. lbs. (25 Nm).
Bleed the power steering system to remove trapped air. Air in the system could cause noise and or damage to the pump.
BLEEDING
This procedure requires the help of an assistant.
With the engine OFF, the wheels off the ground and turned all the
way to the left, fill the fluid reservoir to the FULL COLD mark on the
fluid level indicator.
With an assistant checking the fluid level and condition, bleed
the system by turning the wheels from side to side without hitting the
stops. You should repeat this at least 20 times, making sure to keep the
fluid level at the FULL COLD mark.
Fluid with air in it has a light tan appearance. This air must be
eliminated from the fluid before normal steering action can be obtained.

Start the engine, and while it is idling, recheck the fluid level and add as necessary to reach the FULL COLD mark.
Return the wheels to the center position. Lower the front wheels
to the ground and continue running the engine for 2 or 3 minutes.
Road test the vehicle to make sure the steering functions properly and is free of noises.
