Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engine is off.
Disconnect the negative battery terminal to prevent electrical hazards.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the reservoir cap and check the fluid level.
3. If low, add manufacturer-recommended power steering fluid (check owner's manual for specifications).
4. If fluid is contaminated, proceed to flush the system (see next step).

3. Flush Power Steering System

Sub-steps:
1. Disconnect the return line from the power steering pump.
2. Use a container to catch old fluid as it drains.
3. Reconnect the return line temporarily and fill the reservoir with new fluid.
4. Start the engine and allow it to run until old fluid is expelled into the container.
5. Reconnect the return line securely and top off the fluid level.

4. Inspect and Replace Power Steering Pump (if necessary)

Sub-steps:
1. Remove the serpentine belt by releasing the tensioner.
2. Disconnect the power steering pump from its mounting bracket.
3. Remove the power steering pump hoses carefully to avoid spilling fluid.
4. Install the new power steering pump, ensuring all connections are secure.
5. Reinstall the serpentine belt following the correct routing diagram.

5. Check for Leaks and Test Steering

Sub-steps:
1. Refill the power steering reservoir to the recommended level.
2. Start the engine and turn the steering wheel from lock to lock to purge air from the system.
3. Inspect all connections for leaks.
4. Test drive the vehicle to ensure proper power steering function.
