Solution

1. Preparation

Tools Required: Socket set, screwdrivers, OBD-II scanner, multimeter
Allow the engine to cool down before beginning any work to prevent burns.

2. Address Fluid Leaks

Step 1: Locate and identify any leaking fluids (oil, coolant).
Step 2: Clean the affected area to make future leaks more visible.
Step 3: If oil is leaking, replace the faulty gasket or seal. If coolant is leaking, replace the hose or radiator as necessary.
Step 4: Top off any fluids that were low after repairs are made.

3. Check and Adjust Engine Components

Step 1: Check the engine oil level; add oil if low.
Step 2: Replace oil if it appears burnt or contaminated.
Step 3: Inspect the air filter and replace it if dirty, which could cause overheating.
Step 4: Ensure the belts are in good condition and replace any that are worn or frayed.

4. Brake Inspection

Step 1: Remove the wheel to access the brake components.
Step 2: Inspect brake pads for wear; replace if they are below the minimum thickness.
Step 3: Check for any signs of overheating on the brake rotors; replace if warped or excessively worn.

5. Electrical Inspection

Step 1: Check all wiring and connectors in the engine bay for signs of melting or damage.
Step 2: Repair any damaged wiring with electrical tape or by replacing the wiring harness as needed.
Step 3: Ensure all grounds are secure and free from corrosion.
