The human body runs on various systems. We have our circulatory system, skeletal system, respiratory system, and so on. We need each system to work properly to remain healthy. Our vehicles are the same. They contain a series of systems that work together to keep it functioning properly. Each system needs to be properly maintained and taken care of.

This is the fifth in a series of blogs we will be posting about the various vehicle systems and their function. Please also see:


The engine cooling system has an effect on your vehicle’s engine longevity and overall dependability. The basic parts of the cooling system are responsible for moving heat from the engine and automatic transmission and making sure heat dissipates to the air outside.

Parts of the Engine Cooling System:

  • Coolant (Antifreeze)
  • Cooling fan
  • Cooling reservoir
  • Heater core
  • Hoses
  • Radiator
  • Thermostat
  • Water pump

The water pump is responsible for circulating coolant through the engine. The coolant will absorb heat and return it to the radiator where the heat is dissipated. The thermostat is in place to regulate the temperature of the coolant to keep it consistent for optimal engine operation.


Vehicle cooling systems have advanced over the years as far as new radiator designs and materials, and coolant formulations. With proper, regular vehicle maintenance, the major components of the cooling system can last for many years.  Some factors that impact the replacement of cooling system parts include driving habits, operating conditions, the type of vehicle, the type of coolant used, and the frequency of regular maintenance such as coolant changes.

Signs that maintenance is required on the engine cooling system include:

  • Overheating
  • Leaks
  • Repeatedly needing to add fluid
  • Sweet smell

If you suspect a problem with your engine cooling system, you should have your vehicle inspected immediately. One of the easiest, and most important, items of maintenance for the cooling system is maintaining a healthy amount of coolant (antifreeze). You can check the coolant level in the reservoir under the hood easily. If low, add a mixture of 50/50 approved coolant and distilled water. Remember, to prevent serious injury, you should never open a hot radiator cap. Have the coolant changed with the correct fluid (coolant is vehicle specific) and at the proper intervals as specified in your vehicle’s owner’s manual. If you are consistently losing fluid, you should have the cooling system looked over for leaks.
