Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the negative battery terminal to avoid electrical issues.
2. Inspect and Replace Power Steering Fluid
  • Tools Required: Funnel, clean rags
  • Remove the power steering fluid reservoir cap.
  • Check fluid condition; if it's dark or contaminated, replace it.
  • Use a funnel to add the appropriate power steering fluid, ensuring it reaches the recommended level.
3. Replace Power Steering Pump (if necessary)
  • Tools Required: Socket set, wrench set, power steering fluid, new power steering pump
  • Remove the serpentine belt by loosening the tensioner.
  • Disconnect the power steering pump hoses and remove the pump mounting bolts.
  • Install the new power steering pump in reverse order of removal, ensuring proper torque on the bolts (typically 15-20 ft-lbs).
  • Reconnect the hoses and ensure they are secure.
4. Replace Serpentine Belt (if necessary)
  • Tools Required: Socket set, wrench set, serpentine belt tensioner tool
  • Check the condition of the serpentine belt; replace if worn.
  • Remove the old belt by relieving tension on the tensioner.
  • Install the new belt according to the routing diagram usually found on the engine bay or in the owner's manual.
5. Final Checks
  • Reconnect the negative battery terminal.
  • Start the engine and turn the steering wheel from lock to lock several times to bleed any air from the system.
  • Check the power steering fluid level again and top off as necessary.
