Solution

1. Preparation

Gather tools: coolant, funnel, socket set, OBD-II scanner, and safety gear (gloves, goggles).
Allow the engine to cool down completely before proceeding to avoid burns.

2. Coolant Level Check

Open the hood and locate the coolant reservoir.
Remove the cap slowly to release any pressure.
Check the coolant level and refill with the appropriate coolant mixture if it's low.

3. Inspect for Leaks

Visually inspect hoses, the water pump, and the radiator for any signs of leaks or damage.
If leaks are identified, replace the damaged hoses or components.

4. Radiator Fan Operation

Start the engine and let it idle until it reaches operating temperature.
Monitor the radiator fan; it should engage when the engine temperature rises.
If the fan does not turn on, replace the fan motor or check the fuses and relays.

5. Thermostat Replacement (if faulty)

Drain the coolant from the system.
Remove the thermostat housing bolts and take out the thermostat.
Install a new thermostat, ensuring it is oriented correctly.
Reassemble the housing and refill the coolant system.

6. Radiator Inspection

If the radiator is blocked or damaged, remove it from the vehicle.
Clean or replace the radiator as necessary.
Reinstall the radiator, ensuring all connections are secure.
