1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on the electrical components.

2. Check and Refill Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid level; it should be between the minimum and maximum marks.
If low, add the appropriate power steering fluid (refer to the owner's manual for specifications).

3. Inspect and Repair Leaks

Visually inspect power steering hoses and connections for cracks or leaks.
If leaks are found, replace damaged hoses or seals.
Tighten any loose connections to prevent further leaks.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt using a socket set to relieve tension.
Disconnect the power steering pump from its mounting bracket.
Remove the pump from the vehicle, ensuring to catch any remaining fluid.
Install the new power steering pump in reverse order of removal, ensuring proper alignment.
Reconnect the serpentine belt and check for proper tension.

5. Bleed the Power Steering System

Fill the power steering reservoir with fluid.
Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.
Check the fluid level again and top off as necessary.
