1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Screwdriver set
- Power steering fluid
- OBD-II scanner
Safety Warnings:
- Disconnect the battery before working on electrical systems.
- Allow the engine to cool before working on the power steering system.

2. Check and Refill Power Steering Fluid

Open the hood and locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the recommended type of power steering fluid until it reaches the proper level.
Check fluid condition; if contaminated or dark, proceed to replace fluid.

3. Inspect Power Steering System

Visually inspect all hoses and connections for leaks or damage.
Tighten any loose connections using the socket set as necessary.
Replace any damaged hoses or components if leaks are found.

4. Replace Power Steering Fluid (if necessary)

Place a drain pan under the power steering pump.
Disconnect the return hose from the pump and allow old fluid to drain into the pan.
Reconnect the return hose securely.
Fill the reservoir with new power steering fluid.
Start the engine and turn the steering wheel side to side to bleed air from the system.

5. Check Steering Pump and Motor

Inspect the power steering pump for proper operation, ensuring there are no unusual noises.
If the pump is faulty, remove it using a socket set, and replace it with a new unit following the manufacturer's torque specifications.
For electric power steering systems, test the electric motor for functionality and replace if necessary.
