Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery to prevent electrical shock.

2. Address Overheating Issue

Inspect Coolant System:
- Check for coolant leaks around the radiator, hoses, and water pump.
- If leaks are found, replace damaged hoses or the radiator as necessary.
Replace Thermostat:
- Drain the coolant.
- Remove the thermostat housing and replace the thermostat.
- Refill the cooling system with the appropriate coolant mixture.

3. Check and Replace Damaged Components

Inspect and Replace Belts:
- Remove the serpentine belt using a socket wrench.
- Inspect for cracks or wear; replace if necessary.
- Reinstall the new belt and ensure proper tension.
Check Wiring:
- Inspect wiring harnesses for damaged insulation.
- Repair any damaged wires using electrical tape or heat shrink tubing as needed.

4. Address Oil Leaks

Inspect Oil Pan and Gasket:
- Clean the area around the oil pan.
- If leaks are present, replace the oil pan gasket or the pan itself.
Change Engine Oil:
- Drain the old oil and replace it with the manufacturer-recommended oil.
