Tools Required: Socket set, wrench set, torque wrench
Sub-steps:
1. Remove the power steering belt by loosening the tensioner pulley.
2. Disconnect the power steering lines (be cautious of any fluid spillage).
3. Unbolt the power steering pump from its mounting bracket.
4. Install the new power steering pump and torque bolts to manufacturer specifications.
5. Reconnect power steering lines and ensure they are secured.
6. Reinstall the power steering belt and adjust tension as needed.

4. Bleed the Power Steering System

Tools Required: Helper (if available)
Sub-steps:
1. Fill the power steering reservoir to the full mark.
2. Start the engine and turn the steering wheel from lock to lock several times to circulate fluid.
3. Check and refill fluid as necessary, keeping an eye on the level.
4. Repeat until no air bubbles are present in the reservoir.
