Locate the power steering fluid reservoir.
Remove the cap and check the fluid level.
If low, add the recommended type of power steering fluid (consult the owner’s manual for specifications).

Use a socket set to remove any clamps securing the hoses.
Inspect hoses for cracks, damage, or leaks.
If damaged, replace with new hoses and secure with clamps.

4. Replace Power Steering Pump (if necessary)

Disconnect the power steering pump from the steering system.
Remove the serpentine belt from the pump pulley.
Use a socket set to unscrew the pump mounting bolts and carefully remove the pump.
Install the new power steering pump in reverse order of removal.
Reattach the serpentine belt, ensuring proper tension and alignment.

5. Bleed the Power Steering System

Refill the power steering fluid reservoir to the proper level.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid level again and add as necessary.
