Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Wrench set
- Power steering fluid (type specified by manufacturer)
- Clean funnel
- Clean rags
Safety Warnings:
- Ensure the vehicle is on a level surface and securely supported by jack stands.
- Disconnect the negative battery terminal to prevent accidental electrical issues.

2. Raise the Vehicle

Use the jack to lift the front of the vehicle.
Secure with jack stands to ensure safety while working underneath.

3. Locate the Power Steering Reservoir

Identify and access the power steering fluid reservoir, usually located near the engine on the driver’s side.
Clean around the reservoir cap to prevent contamination when opening.

4. Drain Old Fluid

Using a clean funnel, draw out old fluid from the reservoir using a turkey baster or siphon.
Dispose of the old fluid properly according to local regulations.

5. Refill with New Fluid

Fill the reservoir with new power steering fluid to the recommended level.
Ensure that the correct type of fluid is used as specified in the owner’s manual.

6. Bleed the System

Start the engine and allow it to idle.
Turn the steering wheel from lock to lock several times (approximately 10-15 times) to push air out of the system.
Monitor the fluid level in the reservoir and add more fluid as necessary to maintain the proper level.
After the steering feels smooth, turn the wheel to lock and hold for a few seconds to help expel any remaining air.

7. Check for Leaks

Inspect the power steering hoses and connections for any signs of fluid leaks.
Recheck fluid level in the reservoir and add more fluid if necessary.

8. Lower the Vehicle

Carefully lower the vehicle and remove jack stands.
Reconnect the negative battery terminal.
