Sub-steps:
1. Remove the serpentine belt by loosening the tensioner pulley.
2. Disconnect the power steering pump from its mounting bracket.
3. Remove the inlet and outlet hoses from the pump, being careful to catch any fluid.
4. Install the new power steering pump and reconnect the hoses, ensuring they are secure and leak-free.
5. Reinstall the serpentine belt, following the correct routing.

4. Bleed the Power Steering System

Sub-steps:
1. Fill the power steering reservoir to the appropriate level.
2. Start the engine and turn the steering wheel from lock to lock several times to remove air bubbles.
3. Check the fluid level again and top off if necessary.
