How Does an Auto Cooling System Work?

Jacobson Repair • July 20, 2023

An auto cooling system keeps your engine at a safe operating temperature. But how does an auto cooling system work? Here’s a breakdown:

Coolant

The auto cooling system circulates a mixture of water and coolant throughout the engine to absorb heat. The coolant is usually a mixture of ethylene glycol and water.

Radiator

The coolant is pumped through the engine and then flows through the radiator located in the front of the car. The radiator has a series of small tubes and fins that help dissipate the heat from the coolant.

Fan

The radiator is usually equipped with an electric or mechanical fan that helps pull air through the radiator to dissipate the heat from the coolant. The fan is controlled by a thermostat that turns on when the engine reaches a specific temperature.

Water Pump

The water pump circulates the coolant through the engine and the radiator. The water pump is typically driven by a belt or chain connected to the engine.

Thermostat

The thermostat is a valve that regulates the coolant flow through the engine and the radiator. The thermostat is usually located at the engine end of the upper radiator hose and opens and closes depending on the engine’s temperature.

In conclusion, an auto cooling system circulates a mixture of water and coolant throughout the engine to absorb heat. The coolant flows through the radiator with small tubes and fins that help dissipate heat. A fan pulls air through the radiator, and the water pump circulates the coolant through the engine and radiator. The thermostat regulates the flow of coolant through the engine and radiator.
