2. Drain Old Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Carefully remove the cap from the reservoir.
Use a siphon pump or turkey baster to remove old fluid from the reservoir into the fluid catch pan.
Disconnect the return hose from the power steering pump using pliers, and direct it into the catch pan.
Start the engine briefly (a few seconds) to expel any remaining fluid from the system, then shut off the engine.

3. Flush the System (Optional)

If necessary, fill the reservoir with new power steering fluid and turn the steering wheel from lock to lock several times to circulate the fluid.
Drain the fluid again as described in the previous step.
Repeat this process until the fluid runs clear from the return line.

4. Refilling with New Power Steering Fluid

Reconnect the return hose to the power steering pump securely.
Using a funnel, add new power steering fluid to the reservoir until it reaches the full mark.
Replace the reservoir cap securely.

5. Bleed the Power Steering System

Start the engine and allow it to idle.
Turn the steering wheel from lock to lock several times to remove air from the system.
Check the fluid level in the reservoir and add more fluid if necessary.
