Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal to ensure safety.
2. Check and Refill Power Steering Fluid
  • Locate the power steering fluid reservoir.
  • Remove the cap and check the fluid level; if low, top off with the manufacturer-recommended fluid.
  • Inspect the fluid condition; if it's dark or contaminated, proceed to flush the system.
3. Inspect and Replace Power Steering Pump (if defective)
  • Remove the serpentine belt by loosening the tensioner with a socket wrench.
  • Disconnect the power steering pump from the hoses; use a wrench to loosen the fittings.
  • Remove the mounting bolts securing the pump and take it out.
  • Install the new power steering pump by reversing the removal steps.
  • Torque the mounting bolts to the manufacturer's specified value (usually 25-30 Nm).
4. Inspect and Replace Power Steering Hoses (if leaking)
  • Identify and remove any damaged hoses by loosening the clamps.
  • Replace with new hoses, ensuring proper fit and secure the clamps tightly.
5. Reinstall and Test
  • Reconnect the negative battery terminal.
  • Start the vehicle and turn the steering wheel from lock to lock to bleed air from the system.
  • Check for leaks around the pump and hoses.
