Solution

1. Preparation

Tools Required: Socket set, screwdrivers, coolant pressure tester, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Check Coolant Levels

Sub-steps:
1. Open the hood and locate the coolant reservoir.
2. Remove the cap and inspect the coolant level; it should be between the "MIN" and "MAX" marks.
3. If low, top off with the appropriate coolant type as specified in the owner’s manual.

3. Inspect for Leaks

Sub-steps:
1. Visually inspect the hoses and connections for cracks or wear.
2. Use a coolant pressure tester to check for leaks in the system.
3. Repair or replace any damaged hoses or components as necessary.

4. Test the Thermostat

Sub-steps:
1. Locate the thermostat housing (usually near the engine block).
2. Remove the thermostat for testing (if necessary).
3. Place it in hot water and check if it opens at the specified temperature (usually around 195°F to 220°F).
4. Replace the thermostat if it does not open properly.

5. Inspect the Radiator Fan

Sub-steps:
1. Start the engine and let it reach operating temperature.
2. Observe the radiator fan; it should activate when the engine reaches a certain temperature.
3. If the fan does not engage, inspect the fan relay and electrical connections.
4. Replace the fan motor if it is defective.

6. Clear Airflow Blockages

Sub-steps:
1. Inspect the front grille and radiator for any debris that may obstruct airflow.
2. Clean out any dirt, leaves, or bugs using compressed air or a soft brush.
3. Ensure the air passages are clear for optimal cooling.
