What Is the Engine Cooling System?

Your engine produces a tremendous amount of heat while running. The cooling system circulates coolant (antifreeze) through the engine and radiator to remove excess heat and maintain a safe operating temperature.

The system includes:

  • Radiator

  • Coolant/antifreeze

  • Thermostat

  • Water pump

  • Radiator hoses

  • Cooling fans

Signs Your Cooling System Needs Attention

If you notice any of these symptoms, it’s time to schedule service:

  • Temperature warning light

  • Engine overheating or running hot

  • Coolant leaks (puddles under your car)

  • Steam from the hood

  • Sweet smell (leaking antifreeze)

  • Cabin heat not working during cold weather
