If low, add the appropriate type of power steering fluid as specified in the owner’s manual.
Start the engine and turn the steering wheel from lock to lock to help circulate the fluid, then recheck the fluid level.

3. Inspect and Replace Power Steering Hoses

Use a socket set to remove any clamps securing the power steering hoses.
Check for cracks or leaks in the hoses. Replace any damaged hoses with new ones.
Reattach the hoses and secure them with the clamps.

4. Replace the Power Steering Pump (if necessary)

Remove the serpentine belt by loosening the tensioner pulley with a wrench.
Disconnect the power steering pump from its mounting bracket using a socket set.
Remove the inlet and outlet hoses from the pump.
Install the new pump by reversing the removal steps.
Torque the mounting bolts to the manufacturer's specifications.

5. Bleed the Power Steering System

Fill the power steering reservoir with fluid.
Start the engine and turn the steering wheel slowly from lock to lock several times to remove air from the system.
Recheck the fluid level and top off as necessary.
