Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
- Remove the power steering fluid reservoir cap.
- Use a turkey baster or siphon to extract old fluid.
- Refill with the recommended power steering fluid (consult owner’s manual for specifications).
- Start the engine and turn the steering wheel from lock to lock to circulate the new fluid.
- Check the fluid level again and top off if necessary.

3. Inspect and Replace Power Steering Pump (if needed)

Sub-steps:
- Remove the serpentine belt by releasing the tensioner.
- Disconnect the power steering fluid lines from the pump (be cautious of fluid spillage).
- Unbolt the power steering pump from its mounting bracket.
- Install the new pump in reverse order, ensuring all bolts are torqued to specifications (typically around 18-20 ft-lbs).
- Reconnect the fluid lines and install the serpentine belt.

4. Final Check

Sub-steps:
- Reconnect the battery.
- Start the engine and check for leaks.
- Turn the steering wheel from lock to lock while monitoring the pump operation.
