Solution

1. Preparation

Tools Required: Gloves, rags, funnel, container for old fluid, safety glasses.
Park the vehicle on a level surface and ensure the engine is off and cool.
Safety Warning: Allow the engine to cool before working on the steering system.

2. Remove Contaminated Fluid

Use a turkey baster or siphon to remove as much old fluid from the reservoir as possible.
Dispose of the old fluid properly according to local regulations.
Clean the reservoir with a rag but avoid introducing any debris.

3. Flush the Steering System

Attach a clear hose to the return line of the power steering pump.
Place the other end of the hose in a clean container.
Fill the reservoir with new power steering fluid.
Start the vehicle and turn the steering wheel from lock to lock to circulate the fluid, allowing old fluid to flow into the container.
Stop the engine and check the reservoir fluid level, adding more fluid as needed.
Repeat this process until the fluid being expelled is clean and free of contaminants.

4. Reconnect Components

Reattach the return line securely to the power steering pump.
Ensure all connections are tight to prevent leaks.

5. Final Check

Fill the reservoir to the appropriate level with new power steering fluid.
Start the engine and again turn the steering wheel from lock to lock, checking for any leaks around the connections.
