Solution
1. Preparation
  • Gather tools and materials.
  • Ensure the engine is cool before starting work.
  • Safety gear: gloves and safety glasses.
2. Coolant Level Check
  • Open the hood and locate the coolant reservoir.
  • Remove the cap and verify the coolant level is within the marked range.
  • If low, add the appropriate coolant mixture (50/50 water and antifreeze).
3. Leak Inspection
  • Visually inspect the radiator, hoses, and water pump for any visible leaks or cracks.
  • Use a coolant dye if necessary to detect leaks.
4. Radiator Fan Test
  • Start the engine and let it idle.
  • Turn on the air conditioning and observe if the radiator fan activates.
  • If it does not, check the fan relay or fan motor for faults.
5. Thermostat Inspection
  • Allow the engine to reach operating temperature.
  • Feel the upper radiator hose; it should become hot once the thermostat opens.
  • If the hose remains cold, replace the thermostat.
6. Radiator Cleaning or Replacement
  • If debris is found on the radiator, clean using a soft brush or compressed air.
  • If clogged, consider replacing the radiator with a new unit.
