Disconnect the battery to avoid electrical shorts.
Remove the serpentine belt from the power steering pump.
Unbolt the pump from the mounting bracket using a socket set.
Disconnect the high-pressure and return lines from the pump.
Install the new power steering pump by reversing the removal process. Ensure all connections are tight.
Reinstall the serpentine belt, ensuring it is properly aligned on all pulleys.

4. Bleed the Power Steering System

Reconnect the battery.
Fill the power steering reservoir to the full line with new fluid.
Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
Check the fluid level again and add more fluid if necessary.
