Solution
1. Preparation
  • Tools Required: Safety gloves, safety goggles, funnel, clean rags, OBD-II scanner, torque wrench.
  • Ensure the vehicle is parked on a level surface.
  • Disconnect the battery to avoid electrical shorts.
2. Inspect and Top Up Power Steering Fluid
  • Locate the power steering fluid reservoir.
  • Remove the cap and check the fluid level.
  • If low, top up with the recommended fluid (check owner’s manual for specifications).
  • Inspect fluid for contamination or burnt smell, indicating possible pump failure.
3. Check for Leaks
  • Visually inspect the power steering pump, hoses, and connections for any signs of fluid leakage.
  • Clean any spilled fluid to monitor for fresh leaks after operation.
4. Inspect Power Steering Pump and Belt
  • Check the power steering pump for unusual wear or noise.
  • Inspect the belt for fraying, cracks, or looseness.
  • If the belt is loose, adjust the tension according to manufacturer specifications or replace if damaged.
5. Replace Power Steering Pump (if necessary)
  • Tools Required: Socket set, torque wrench, fluid catch pan.
  • Remove the serpentine belt from the power steering pump pulley.
  • Disconnect the fluid lines from the pump, using a catch pan to collect any fluid.
