Solution

1. Preparation

Gather tools and parts: Ensure you have an OBD-II scanner, socket set, multimeter, coolant pressure tester, and safety glasses.
Disconnect the battery: Always disconnect the negative terminal to ensure safety while working on electrical components.

2. Inspect and Replace Damaged Components

Inspect wiring and connectors:
- Remove any damaged or melted wiring.
- Use electrical tape or heat-shrink tubing to repair minor damage, or replace damaged wires entirely.
Check and replace belts:
- If belts are frayed or worn, remove the serpentine belt using a wrench to release tension.
- Replace with a new belt of the same specifications and ensure proper tensioning.

3. Check and Refill Fluids

Inspect and refill engine oil:
- Remove the oil dipstick, check the level and condition.
- If low, add manufacturer-recommended oil until the proper level is reached.
Inspect and refill coolant:
- Open the coolant reservoir cap carefully (ensure the engine is cool).
- Check the coolant level and top up with a 50/50 mixture of antifreeze and water if low.

4. Test Cooling System

Pressure test the cooling system:
- Attach the coolant pressure tester to the coolant reservoir.
- Pump to the recommended pressure and check for leaks. Replace any faulty hoses or components if necessary.
