Solution

1. Preparation

Gather tools: socket set, screwdriver, coolant, OBD-II scanner.
Ensure the engine is cool before beginning work.
Disconnect the battery to avoid electrical hazards.

2. Coolant Check and Refill

Sub-steps:
1. Remove the radiator cap carefully to avoid steam burns.
2. Check the coolant level in the radiator and reservoir; refill with the appropriate coolant if low.
3. Inspect for any visible signs of contamination in the coolant (like oil or rust).

3. Inspect and Repair Leaks

Sub-steps:
1. Visually inspect all hoses and connections for signs of wear or leaks.
2. Tighten any loose clamps or replace damaged hoses.
3. If leaks are found, replace the affected components (hoses or gaskets).

4. Thermostat Replacement (if faulty)

Sub-steps:
1. Locate the thermostat housing (usually near the engine block).
2. Remove the bolts securing the housing using a socket set.
3. Carefully remove the old thermostat and clean the mating surfaces.
4. Install the new thermostat, ensuring it is oriented correctly.
5. Reattach the housing and torque the bolts to manufacturer specifications.

5. Radiator Fan Check

Sub-steps:
1. Disconnect the electrical connector from the radiator fan.
2. Test the fan with a direct power source to ensure functionality.
3. If the fan does not operate, replace the fan motor.
