Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while working.

2. Identify and Repair Leaks

Inspect Hoses and Fittings:
- Use a flashlight to check all hoses, clamps, and fittings for signs of leaks.
- Tighten any loose connections.
- Replace any damaged hoses with new ones.
Examine the Power Steering Pump:
- Remove the pump from its mounting by loosening the bolts using a socket set.
- Inspect the pump for leaks around the seals and casing.
- If leaking, replace the pump with a new unit and torque bolts to manufacturer specifications (consult service manual for exact torque values).
Check the Steering Rack:
- If the steering rack is leaking, it may need to be replaced. Follow the manufacturer's instructions for removal and installation.

3. Refill Power Steering Fluid

Choose Appropriate Fluid:
- Consult the owner’s manual to select the correct type of power steering fluid.
Refill the Reservoir:
- Use a funnel to carefully add fluid to the reservoir until it reaches the full mark.
- Start the engine and turn the steering wheel from lock to lock several times to circulate the fluid and remove air bubbles.

4. Finalize and Clean Up

Inspect for any remaining leaks after refilling.
Reconnect the battery and ensure all tools are removed from the engine bay.
Dispose of old fluid and any replaced parts according to local regulations.
