Remove the serpentine belt from the power steering pump by releasing the tensioner.
Disconnect the power steering lines from the pump.
Remove the mounting bolts securing the pump and replace with a new power steering pump.
Reconnect the lines and install the serpentine belt, ensuring proper tension.
