Connect a pressure gauge to the power steering pump.
Start the engine and turn the steering wheel to check for proper pressure.
If the pump is faulty, disconnect the battery and remove the serpentine belt.
Unbolt the power steering pump from its mounting and replace it with a new unit, ensuring proper alignment of the belt.
