Cooling System

What Is a Car Cooling System? | Engine Cooling System Overview

The car cooling system is a critical part of your vehicle’s engine performance and reliability. Its main function is to regulate engine temperature, prevent engine overheating, and protect components from heat damage. Without a properly working engine cooling system, your car could suffer serious issues like a blown head gasket, warped engine block, or radiator failure.

​

 

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.
