Solution
1. Preparation
  • Tools Required: Wrench set, fluid catch pan, power steering fluid, rags
  • Park the vehicle on a level surface and engage the parking brake.
  • Allow the engine to cool if it has been running.
2. Check and Refill Power Steering Fluid
  • Remove the power steering fluid reservoir cap and check the fluid level.
  • If low, add the appropriate type of power steering fluid as specified in the owner’s manual.
  • Replace the cap securely.
3. Inspect and Replace Leaky Components
  • Tools Required: Socket set, torque wrench, new power steering hoses or pump as necessary
  • If any leaks are found, determine if the power steering pump, hoses, or rack needs replacement.
  • For component replacement:
    • Disconnect the battery to avoid electrical issues.
    • Remove any obstructing components (if necessary).
    • Use wrenches to disconnect the power steering hoses from the pump and rack.
    • Replace with new hoses or pump as required.
    • Reattach all connections and ensure they are secure.
4. Check and Replace Serpentine Belt
