Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: Wrench set, OBD-II scanner, fluid catch pan.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, add the appropriate type of power steering fluid (refer to the owner's manual for specifications).
Replace the cap securely after filling.

3. Repair or Replace Leaky Components

If leaks are found, identify the source (hoses, seals, or the steering rack).
For hose replacements, use a wrench to disconnect the leaky hose and replace it with a new one, ensuring clamps are secure.
If the steering rack is leaking, it may require replacement. Follow the manufacturer's guidelines for removal and installation.

4. Inspect and Replace Serpentine Belt

If the serpentine belt is worn or loose, remove it by releasing tension using a wrench on the tensioner pulley.
Replace with a new belt, ensuring proper routing according to the belt diagram usually found on the engine cover.

5. Clear Error Codes

After repairs, use the OBD-II scanner to clear any error codes that were logged during diagnostics.
Ensure all systems are functioning correctly.
