Thousands of automobiles are stranded on the side of the road each year due to cooling system problems. Precautions can be taken to avoid this, including paying attention to the temperature gauge. Engine coolant carries away excess heat from the engine. Too much heat can destroy an engine, while an engine that is not at the proper operating temperature will run inefficiently. This course will help you identify the purpose of the cooling system, describe the cooling system’s components, define coolant properties, explain how coolant flows in an engine, describe how charge-air coolers work, identify how active warm-up works, test and service the cooling system, and change a passenger cabin filter.
