Solution

1. Preparation

Gather tools: Socket set, OBD-II scanner, coolant, thermometer, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Coolant

Remove the coolant reservoir cap.
If low, add the appropriate coolant type as per the manufacturer's specifications.
Check for leaks and repair any damaged hoses or connections.

3. Replace Thermostat (if faulty)

Drain the coolant from the radiator.
Remove the thermostat housing using a socket set.
Replace the thermostat with a new one, ensuring the gasket is also replaced.
Reinstall the thermostat housing and tighten to the specified torque.

4. Check and Repair Cooling Fans

Inspect the electric cooling fans for proper functionality.
If faulty, disconnect the electrical connector and remove the fan assembly.
Replace with a new fan assembly and reconnect the electrical connector.

5. Flush and Refill Radiator

Flush the radiator using a radiator flush solution to remove any blockages.
Refill with recommended coolant type and ensure there are no air pockets by running the engine with the radiator cap off until the thermostat opens.
