Tools Required: Socket set, torque wrench, wrench set, power steering pump pulley puller
Disconnect the negative battery terminal.
Remove any components obstructing access to the power steering pump (e.g., air intake hoses).
Remove the serpentine belt from the power steering pump pulley.
Unbolt and remove the power steering pump from its mounting.
Install the new power steering pump and torque bolts to manufacturer's specifications.
Reinstall the serpentine belt and any removed components.

4. Check and Replace Power Steering Belt (if necessary)

Tools Required: Socket set, torque wrench
Inspect the power steering belt for cracks or excessive wear.
If damaged, remove the belt by loosening the tensioner.
Install the new power steering belt, ensuring proper alignment on the pulleys.
Adjust the tensioner according to specifications.

5. Bleed the Power Steering System

Tools Required: Clean container
With the engine running, turn the steering wheel all the way to the left and then to the right several times.
Check fluid level and add more if necessary.
Ensure there are no air bubbles in the reservoir.
