Solution

1. Preparation

Tools Required: Gloves, rags, funnel
Ensure the vehicle is parked on a level surface and the engine is turned off. Allow the engine to cool if it has been running.

2. Add Power Steering Fluid

2. For hose leaks, replace the damaged hose with a new one, ensuring proper fittings.
3. If the pump is leaking, replace the power steering pump.
4. Tighten any loose fittings and check for proper sealing.

4. Flush and Replace Fluid (if necessary)

Sub-steps:
1. If the fluid is contaminated, perform a power steering fluid flush.
2. Disconnect the return line from the power steering pump.
