Solution

1. Preparation

Tools Required:
- Socket set
- Screwdriver set
- Fluid catch pan
- Funnel
- Rags
Safety Warnings:
- Disconnect the battery before starting work to avoid electrical issues.
- Allow the engine to cool before beginning work.

2. Drain Old Power Steering Fluid

Locate the power steering fluid reservoir (usually near the front of the engine bay).
Using a siphon pump or turkey baster, remove as much old fluid as possible from the reservoir.
Place a fluid catch pan under the power steering pump and disconnect the return hose from the pump. Be prepared for residual fluid to drain.
Allow the old fluid to fully drain into the pan.

3. Flush the Power Steering System (Optional but recommended)

Reconnect the return hose to the pump securely.
Refill the power steering reservoir with new fluid.
Start the engine and turn the steering wheel from lock to lock several times. This will help circulate the new fluid and push out any remaining old fluid.
Turn off the engine and check the fluid level, adding more if necessary.

4. Fill with New Power Steering Fluid

Using a funnel, fill the power steering reservoir with the manufacturer-recommended power steering fluid (check the owner's manual for specifications).
Ensure the fluid level is at the "full" mark on the reservoir.

5. Final Checks

Start the engine and check for any leaks around the power steering pump and hoses.
Turn the steering wheel to ensure smooth operation and listen for any abnormal sounds.
Recheck the fluid level and add more if necessary.
