    • If low, add the appropriate type of power steering fluid (consult the owner's manual for specifications).
  • Tools Required: None
  • Safety Warnings: Avoid overfilling the reservoir.
3. Check for Leaks
  • Sub-steps:
    • Visually inspect all power steering hoses and connections for signs of fluid leaks.

  • Tools Required: None
  • Safety Warnings: Ensure the engine is off to prevent accidental movement.
4. Inspect Power Steering Pump
  • Sub-steps:
    • Locate the power steering pump and check for signs of wear or damage.
