Solution

1. Preparation

Tools Required: Socket set, wrench set, fluid catch pan, power steering fluid, UV dye (if applicable).
Park the vehicle on a level surface and turn off the engine.
Allow the engine to cool before starting work.

2. Locate the Leak

Sub-steps:
- Clean the area around the power steering components with a degreaser.
- Use a UV dye if initial visual inspection does not reveal the leak and check under UV light after running the engine briefly.

3. Replace Damaged Components

Sub-steps:
- If the leak is from a hose, use the appropriate size socket or wrench to disconnect the hose from the power steering pump or steering rack.
- Replace the damaged hose with a new one, ensuring it matches the original specifications.
- If the leak is from the power steering pump, remove the mounting bolts and disconnect the pump from the system. Replace with a new pump and ensure all seals are properly seated.
- If the steering rack is leaking, it may require replacement or resealing which can be more complex.
