Solution

1. Preparation

Tools Required: Wrench set, fluid catch pan, OBD-II scanner, flashlight, rags.
Safety Warnings: Ensure the engine is off and cool before working on the power steering system.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the markings.
If low, add the recommended power steering fluid until it reaches the appropriate level.
Replace the cap securely.

3. Repair or Replace Leaking Components

If leaks are found:
- Hoses: Loosen the clamps and remove the affected hose. Replace with a new hose and tighten clamps securely.
- Pump: Disconnect the power steering pump by removing the bolts. Install a new pump by reversing the removal process and ensure all connections are tight.
- Steering Rack: For leaks at the rack, follow the manufacturer's instructions for replacement, which typically involves disconnecting the steering linkage and fluid lines.

4. Inspect and Replace the Drive Belt

Check the drive belt for wear, cracks, or looseness.
If worn, use a wrench to relieve tension on the tensioner pulley and remove the belt.
Install a new belt by following the routing diagram usually found on a sticker in the engine bay.

5. Test the Power Steering System

After completing repairs, start the engine and turn the steering wheel from lock to lock several times to bleed any air from the system.
Check for leaks again after running the engine.
