Solution
1. Preparation
  • Gather tools: OBD-II scanner, coolant tester, multimeter, and basic hand tools.
  • Ensure the vehicle is parked on a flat surface and turned off. Allow the engine to cool before starting work.
2. Check Coolant Level
  • Locate the coolant reservoir under the hood.
  • Remove the cap and visually inspect the coolant level.
    • If low, add the recommended coolant type (usually a 50/50 mix of distilled water and coolant).
  • Replace the cap securely.
3. Inspect Cooling Fans
  • Turn on the vehicle and allow it to go into ready mode.
  • Listen for the cooling fans; they should activate when the vehicle temperature rises.
  • If not, check the fan wiring and fuses for continuity using a multimeter. Replace any faulty components.
4. Test Coolant System
  • Use a coolant tester to check for leaks in the system.
  • Conduct a pressure test if necessary to identify hidden leaks in hoses or the radiator.
  • Replace any leaking hoses or faulty components as needed.
5. Clean Cabin Air Filter
  • Locate the cabin air filter housing, typically behind the glove compartment.
  • Remove the filter and inspect it for dirt and debris.
  • Clean or replace the filter if it is clogged.
