Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the vehicle's 12V battery to prevent electrical hazards.

2. Locate the Leak

Sub-steps:
- Remove the engine cover (if applicable) to access the power steering components.
- Use a flashlight to inspect the power steering pump, hoses, and steering rack for any visible leaks.
- If using UV dye, add it to the power steering fluid and run the vehicle for a short time, then check for fluorescence with a UV light.

3. Repair the Leak

Sub-steps:
- If the leak is from a hose, replace the damaged hose with a new one. Use a hose clamp to secure it.
- If the power steering pump is leaking, remove the pump by disconnecting the power steering lines and electrical connections. Replace it with a new pump and ensure all connections are tight.
- For leaks at the steering rack, if it's a minor seal issue, replace the O-rings or seals. If major damage is found, consider replacing the steering rack.

4. Refill Power Steering Fluid

Sub-steps:
- Use the recommended power steering fluid type specified in the owner’s manual.
- Fill the power steering reservoir to the proper level and check for leaks during the filling process.

5. Reassemble and Test

Sub-steps:
- Reconnect the battery and any components that were removed during the repair.
- Start the vehicle and turn the steering wheel from lock to lock several times to bleed the system.
- Check the power steering fluid level again and top off if necessary.
