The cooling system in a car circulates coolant (a mix of water and antifreeze) through the engine block, cylinder head, and radiator to absorb and dissipate excess heat.

 

Key components of the system include:

​

• Radiator – Disperses heat from coolant

• Water Pump – Circulates coolant throughout the system

• Thermostat – Regulates coolant flow based on engine temperature

• Radiator Fan – Helps cool the radiator when the vehicle is idling or moving slowly

• Coolant Reservoir – Stores excess coolant for future circulation

• Hoses and Clamps – Carry coolant to and from the radiator and engine

​

Together, these components work to maintain an optimal engine temperature range—usually between 195°F and 220°F—for maximum fuel efficiency and performance.
