Solution

1. Preparation

Tools Required: OBD-II scanner, fluid pump, socket set, multimeter, torque wrench, power steering fluid.
Ensure the vehicle is on a flat surface and the ignition is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replenish Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick or markings.
If low, add the manufacturer-recommended power steering fluid until it reaches the proper level.
Replace the cap securely.

3. Inspect and Repair Leaks

Visually inspect all hoses and connections for signs of leaks or wear.
Replace any damaged hoses or fittings with OEM parts.
Ensure all connections are tight to prevent further leaks.

4. Test Power Steering Pump

Reconnect the battery.
Use the multimeter to check voltage at the power steering pump while the engine is running.
If voltage is absent or fluctuating, the pump may need replacement.
If the pump is noisy or shows signs of failure, replace it with an OEM unit.

5. Inspect Drive Belt

Check the drive belt for wear, cracks, or lack of tension.
If the belt is worn or loose, adjust the tension or replace it as necessary.
Ensure all pulleys are aligned correctly and functioning properly.
