How to Fix It
It's time to fix that overheating issue so that you can enjoy the chilled air without any worries. Follow these simple fixes:

- Clean the Radiator: Cleaning the radiator will remove any blockages restricting the airflow passage. Also, use a radiator testing kit to inspect the leakages.
- Replace Coolant Mixture: You need to replace the coolant mixture every two years or 40,000 km. Ensure that you pick a coolant mixture with the right concentration.
