So, The cooling system is composed of various parts: the radiator, pressure cap, fan, pump, thermostat, hoses and overflow tank.
So, The primary job of the cooling system is to prevent the engine; from overheating by transferring engine heat to the air. But that’s not all. As a result, Engines are designed to operate within a specific temperature range for optimum efficiency.
When the engine is cold, components wear out faster, and the engine is less efficient and emits more pollution. So another important job of the cooling system is to; make sure the optimum engine operating temperature is obtained as rapidly as possible and is then kept constant.
All the parts that make up the cooling system serve both purposes and ensure the system properly absorbs; transports and dissipates heat.
The best way is to take a holistic approach and to examine the entire cooling system; for wear as well as for any irregularities.

So, For a cooling system to function properly it needs several things; proper coolant mixture and level; sufficient pressure; adequate coolant flow and sufficient airflow. When and where a vehicle overheats provides a tech with valuable diagnostic clues; as to which of these may be missing. Driving at highway speed, for example; can offset a cooling fan or fan clutch failure that prevents sufficient airflow at slower speeds. A failure to overheat at highway speeds may also confirm adequate coolant flow; including proper thermostat operation.
