Solution

1. Preparation

Gather necessary tools and parts before starting.
Tools Required: Socket set, OBD-II scanner, fluid catch container, funnel, rags.
Ensure the vehicle is parked on a level surface with the engine off.

2. Fluid Replacement

Locate the power steering reservoir and remove the cap.
Using a fluid catch container, siphon out old fluid from the reservoir.
Fill the reservoir with new power steering fluid as per the manufacturer's specifications.
Reattach the cap securely.

3. Inspect and Replace Components

Inspect Power Steering Pump:
- Disconnect the battery to ensure safety.
- Remove mounting bolts using a socket set and carefully take out the pump.
- Inspect the pump for any visible damage or wear.
- If damaged, replace with a new pump.
Inspect Hoses:
- Check hoses for cracks or leaks.
- Replace any damaged hoses with new ones, ensuring proper fitment and securing with clamps.

4. System Bleeding

After replacing fluid and any components, start the engine.
Turn the steering wheel fully to the left and then to the right several times to help bleed air from the system.
Monitor fluid level and add more if necessary to maintain proper levels.

5. Final Checks

Reconnect the battery.
Start the engine and check for leaks around the pump and hoses.
Test drive the vehicle to ensure proper operation of the power steering system.
