Solution

1. Preparation

Gather tools and materials: funnel, new power steering fluid (consult owner's manual for specifications), rags, and safety glasses.
Park the vehicle on a level surface and turn off the engine.
Put on safety glasses to protect eyes from fluid.

2. Drain Old Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Use a turkey baster or siphon to remove as much old fluid as possible from the reservoir.
Dispose of the old fluid in accordance with local regulations.

3. Refill with New Power Steering Fluid

Using a funnel, fill the reservoir with the recommended power steering fluid until it reaches the "FULL" mark.
Avoid overfilling, as this can cause foaming and poor steering performance.

4. Bleed the Power Steering System

Start the engine and turn the steering wheel fully left and right several times to circulate the new fluid and remove air bubbles.
Check the fluid level again and add more fluid if necessary to maintain the correct level.

5. Final Inspection

Inspect hoses and connections for any signs of leaks.
Ensure the power steering fluid reservoir cap is securely fastened.
