2. Locate and Repair Leaks

Inspect Power Steering Hoses:
- Check all hoses connected to the power steering system for frays or cracks.
- If leaks are found, replace the damaged hoses with new ones.
Examine Power Steering Pump:
- Remove the belt from the power steering pump using a socket set.
- Unbolt the power steering pump and inspect for leaks from the pump body or seals.
- Replace the pump if leaks are present.
Check Steering Rack:
- Inspect the steering rack and pinion for any visible leaks.
- If leaks are found, the steering rack may need to be rebuilt or replaced.

3. Refill Power Steering Fluid

After repairs, refill the power steering reservoir with the manufacturer-recommended fluid type (typically Honda Power Steering Fluid).
Bleed the power steering system to remove air bubbles by turning the steering wheel from lock to lock several times.

4. Testing

Reconnect the negative battery terminal.
Start the vehicle and check for leaks around repaired areas.
Test the steering operation to ensure it is smooth and responsive.
