Solution

1. Preparation

Tools Required: Socket set, screwdriver set, OBD-II scanner, coolant.
Ensure the engine is cool before beginning any repairs to avoid burns.

2. Check Coolant Level

Open the hood and locate the coolant reservoir and radiator cap.
Remove the cap from the coolant reservoir; if low, add the appropriate coolant mixture.
Check the radiator cap for damage; replace if necessary.

3. Inspect Cooling System Components

Radiator:
- Inspect for cracks or corrosion.
- If damaged, replace the radiator.
Hoses:
- Look for any signs of wear, cracks, or leaks in the hoses.
- Replace any damaged hoses.

4. Thermostat Replacement

Disconnect the negative terminal of the battery.
Drain the coolant from the radiator.
Remove the thermostat housing and the old thermostat.
Install the new thermostat, ensuring it is oriented correctly.
Reattach the thermostat housing and refill the coolant.

5. Water Pump Inspection

Check for any coolant leaks around the water pump.
If needed, remove the water pump (may require removal of timing belt).
Replace the water pump if it shows signs of failure.

6. Radiator Fan Check

Start the engine and allow it to reach normal operating temperature.
Monitor the radiator fan; it should activate as the engine heats up.
If the fan does not operate, check the fan fuse and relay; replace if faulty.
