Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Fluid pump
- OBD-II scanner
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean

Remove any debris or dirt around the steering rack area.
Clean the power steering fluid reservoir cap and surrounding area to prevent contamination.

3. Check Power Steering Fluid

Remove the power steering fluid reservoir cap and check the fluid level.
If the fluid is low, refill it with the manufacturer's recommended type.
If the fluid is contaminated (dark or has debris), proceed to replace it.

4. Replace Power Steering Fluid

Use a fluid pump to drain the old power steering fluid into a suitable container.
Refill the reservoir with new power steering fluid until it reaches the recommended level.
Start the vehicle and turn the steering wheel from lock to lock to circulate the new fluid.
