Solution

1. Preparation

Tools Required:
- Socket set
- Fluid extraction pump or turkey baster
- Funnel
- Drain pan
- Clean rags
Safety Warnings:
- Ensure the engine is off and cool before starting.
- Wear gloves to protect hands from fluid.

2. Drain Old Power Steering Fluid

Locate the Power Steering Reservoir:
- Open the hood and identify the power steering reservoir.
Remove Old Fluid:
- Use a fluid extraction pump or turkey baster to siphon out the old fluid from the reservoir.
- Dispose of the old fluid properly in accordance with local regulations.
Drain Remaining Fluid:
- If necessary, detach the return hose (usually the lower hose) from the power steering pump, placing a drain pan underneath to catch fluid. Allow remaining fluid to drain completely.

3. Flush the System (Optional but Recommended)

Reconnect the Return Hose:
- Reattach the return hose securely to the power steering pump.
Add New Power Steering Fluid:
- Using a funnel, fill the reservoir with new power steering fluid, making sure to use the manufacturer-recommended fluid type.
Cycle the Steering:
- Start the engine and turn the steering wheel from lock to lock several times to help flush out any remaining old fluid and mix with the new fluid.
- Check the fluid level and add more fluid if necessary.

4. Final Check

Inspect for Leaks:
- With the engine running, visually inspect all hoses and connections for leaks.
Top Off Fluid:
- Ensure the fluid level is at the correct mark on the reservoir.
