Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and securely parked.
Disconnect the battery to prevent any electrical issues during the process.

2. Locate the Power Steering Reservoir

Open the hood and locate the power steering fluid reservoir. It is typically situated near the engine and labeled.
Remove the cap from the reservoir.

3. Drain Old Power Steering Fluid

Place a drain pan under the vehicle to catch the old fluid.
Locate the power steering return line connected to the reservoir.
Use a wrench to loosen the hose clamp and detach the return line from the reservoir.
Allow the old fluid to drain completely into the pan.

4. Flush the System (Optional)

If necessary, use a power steering fluid flush solution. Follow the manufacturer's instructions.
Reconnect the return line and fill the reservoir with the flush solution.
Start the engine and turn the steering wheel from lock to lock several times to circulate the flush.
Turn off the engine and drain the flush solution as described in the previous step.

5. Add New Power Steering Fluid

Reconnect the return line to the reservoir and secure it with a hose clamp.
Fill the reservoir with new power steering fluid, ensuring it meets Toyota specifications (typically Dexron III or equivalent).
Replace the reservoir cap securely.

6. Check for Leaks

Start the engine and let it idle.
Check for any leaks around the power steering system.
Turn the steering wheel left and right to circulate the new fluid.

7. Finalize and Clean Up

If no leaks are detected, reconnect the battery.
Dispose of the old power steering fluid and any used materials according to local regulations.
