2. Check the fluid level against the dipstick markings.
3. If low, top off with the recommended power steering fluid.
4. Replace the cap securely after refilling.

4. Inspect Alternator and Accessories

Tools Required: Visual inspection tools, socket set.
Instructions:
1. Disconnect the electrical connector from the alternator.
2. Remove the alternator belt for direct inspection.
