Bleeding Hydraulic System

WARNING: This page is about a different car, the 2002 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

Raise the front end of vehicle until the wheels are clear of the ground.
Add Genuine NISSAN PSF II or equivalent, into the steering fluid reservoir tank to the specified level. Then quickly turn the steering wheel fully to right and left and lightly touch steering stoppers. Repeat steering wheel operation until the fluid level no longer decreases.

Start the engine then repeat step 2 above. Incomplete air bleeding will cause the following symptoms:
- Air bubbles in reservoir tank
- Clicking noise in oil pump
- Excessive buzzing in oil pump
  If this happens, bleed out the air repeating step 2 above. Fluid noise may occur in the valve or oil pump. This is common when the vehicle is stationary or while turning the steering wheel slowly. This does not affect the performance or durability of the system.
