Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical issues while working on the power steering system.

2. Identify and Repair Leaks

Inspect hoses:
- Use a socket set to loosen the hose clamps.
- Remove any damaged hoses and replace them with new ones.
- Tighten new hose clamps to manufacturer specifications (usually about 7-10 Nm).
Replace power steering pump (if leaking):
- Remove the serpentine belt using a belt tensioner tool.
- Unbolt the power steering pump from its mounting bracket (typically 3-4 bolts).
- Disconnect the fluid lines from the pump (use a wrench to avoid stripping).
- Install the new pump and reconnect fluid lines and the serpentine belt.
- Torque bolts to manufacturer specifications (consult service manual for exact values).

3. Refill Power Steering Fluid

Use the recommended power steering fluid (check owner's manual).
Fill the reservoir to the appropriate level and turn the steering wheel to work the fluid into the system.

4. Final Checks

Reconnect the battery.
Start the engine and check for leaks again while the power steering system is operating.
Test the steering feel to ensure proper function.
