Solution

1. Preparation

Tools Required: Safety goggles, gloves, flashlight, OBD-II scanner, basic socket set
Ensure the vehicle is parked on a flat surface and the engine is cool before starting repairs.

2. Addressing Engine Oil Leaks

Inspect Oil Lines: Check oil lines and the oil filter for leaks.
Tighten Loose Fittings: If any fittings are loose, tighten them to prevent leaks.
Replace Damaged Seals: If any seals are damaged, replace them with new ones. Ensure proper torque specifications are followed.

3. Electrical Component Inspection

Disconnect Battery: Disconnect the negative terminal of the battery to prevent electrical shorts.
Inspect Wiring: Check all wiring harnesses for fraying or damage, especially near hot engine components.
Repair or Replace: Repair any damaged wiring or connectors. If components are burnt, replace them as necessary.

4. Brake Component Check

Inspect Brake Pads: Remove the wheels and inspect brake pads for excessive wear or glazing.
Replace Brake Pads: If the pads are worn down, replace them with new ones. Use a torque wrench to ensure proper torque on caliper bolts.
Check Brake Fluid: Ensure there is adequate brake fluid in the reservoir. If low, fill with the appropriate fluid type.
