Car overheating problems are one of the most common causes of serious engine damage. Issues within the engine cooling system—such as a failing radiator, thermostat, or water pump—can quickly lead to rising temperatures, coolant loss, and costly repairs.
This category focuses on diagnosing and fixing engine cooling system problems and heater performance issues. You’ll learn how to identify coolant leaks, airflow restrictions, and components that fail under heat and pressure.
Common problems covered:
