The COOLING SYSTEM keeps our engine from overheating while you are driving around. Its job is to move heat away from the engine.

The RADIATOR is the part most everyone associates with the cooling system. Coolant flows through the radiator which has fine cooling fins that draw the heat out of the coolant and dissipate it into the air. To make sure there's enough airflow over the radiator, a fan pulls air over the cooling fins even when the car is idling. In some vehicles, the fan is powered by the serpentine belt. On others, an electric motor runs the fan. Electric fans
turn on and off as needed. You may have heard the fan kick on shortly after you turn your car off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.

A hose connects the radiator to the water pump. The water pump pushes the water into the engine block. Now the engine block and cylinder heads have passages for the coolant to pass through without getting into the oil or the combustion chamber. These passages are referred to as the "water jacket".

While the coolant is passing through the water jacket, it absorbs heat from the engine on its way to the radiator for cooling. Between the engine and the radiator is a gatekeeper called the thermostat. The thermostat's job is to regulate the temperature of the engine just like your home thermostat regulates the temperature of your house. It gets your engine up to the correct operating temperature and then keeps it from overheating.

When your first start the engine, it's very cold and needs to warm up. So the thermostat blocks the flow of coolant to the radiator. As the engine warms up, the thermostat starts to let coolant flow through the system.
