Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues during repair.

2. Locate the Leak

Inspect the power steering hoses for any visible damage or loose connections.
If the hoses are leaking, mark the locations for replacement.

3. Remove and Replace Damaged Hoses

Tools Required: Socket set, wrench set, fluid catch pan.
Sub-steps:
1. Place a fluid catch pan under the power steering system to catch any residual fluid.
2. Using the socket set, remove the clamps securing the affected power steering hose(s).
3. Detach the hose from both ends and remove it from the vehicle.
4. Install the new power steering hose by reversing the removal process, ensuring all clamps are securely tightened to manufacturer specifications.

4. Replace Power Steering Fluid

Tools Required: Funnel, fluid catch pan.
Sub-steps:
1. Refill the power steering reservoir with the appropriate type of fluid as specified in the owner’s manual (typically CHF 202 or equivalent).
2. Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
3. Check the fluid level and add more as needed.

5. Final Inspection

Inspect all connections and hoses to ensure there are no leaks.
Reconnect the negative battery terminal.
