Solution

1. Preparation

Tools Required: Socket set, screwdriver set, OBD-II scanner, coolant.
Safely park the vehicle on a level surface and allow the engine to cool down completely.
Disconnect the battery to prevent electrical shocks while working.

2. Coolant Inspection

Open the hood and locate the coolant reservoir and radiator cap.
Sub-steps:
- Remove the radiator cap carefully to avoid hot steam.
- Check for the coolant level; if low, refill with the appropriate coolant mixture (50/50 water and coolant).
- Inspect for any signs of coolant contamination or discoloration.

3. Leak Check

Tools Required: Clean cloth or paper towel.
Inspect under the vehicle for any coolant leaks.
Sub-steps:
- Wipe around hoses and connections to identify leaks.
- Replace any damaged hoses or clamps as necessary.

4. Radiator Fan Test

Locate the radiator fan and check its operation.
Sub-steps:
- Start the engine and allow it to reach operating temperature.
- Observe if the radiator fan activates when the engine gets hot.
- If it does not, check the fan relay and fuses, replacing any faulty components.

5. Thermostat Replacement (if necessary)

Tools Required: Socket set, gasket scraper, new thermostat, thermostat gasket.
If the thermostat is suspected to be stuck closed:
- Drain the coolant from the radiator.
- Remove the thermostat housing by unscrewing the bolts.
- Replace the old thermostat with a new one, ensuring proper alignment with the gasket.
- Refill the cooling system with the appropriate coolant.

6. Radiator Inspection

Check for blockages or damage to the radiator.
Sub-steps:
- Remove any debris or obstructions from the radiator fins.
- If damaged, consider replacing the radiator entirely.
