Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely raised on jack stands if needed.
Disconnect the battery to avoid any electrical issues during repair.

2. Locate the Leak

Inspect the Power Steering Reservoir: Remove the cap and check for cracks or damage. If damaged, replace the reservoir.
Examine Hoses: Visually inspect all hoses connected to the power steering system, looking for cracks or wear. Replace any damaged hoses.

3. Replace Damaged Components

Power Steering Pump Replacement:
- Remove the drive belt from the power steering pump.
- Disconnect the power steering lines (make sure to have a catch pan to collect any fluid).
- Unbolt the pump from its mounting bracket.
- Install the new pump by reversing the removal steps, ensuring all connections are secure.
Repairing Hoses:
- If the hoses are leaking, use a hose clamp to tighten them if they are loose. If they are damaged, cut the damaged section and replace it with the appropriate size hose, securing with clamps.

4. Refill and Bleed the System

Refill the power steering reservoir with the correct type of power steering fluid as specified in the owner's manual.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check for leaks around the newly replaced components.

5. Final Inspection

After a test drive, recheck the fluid level and inspect for any signs of leakage.
