What is the coolant system?

The coolant system in your vehicle consists of the radiator, hoses, a heater core, water pump, cooling fan, a thermostat, coolant reservoir, and engine coolant fluid or more commonly known as antifreeze.

The engine cooling system affects your vehicles overall dependability and engine longevity. If you suspect a problem with your cooling system, you should have it checked immediately.

What does the coolant system do?

The coolant system dissipates heat from the engine and transmission. The water pump cycles the coolant through the engine to absorb heat then returns the heated fluid to the radiator where the heat is then dissipated.

Some factors that affect the replacement of cooling system parts include:

  • Driving habits
  • Operating conditions
  • Type of vehicle
  • Type of coolant
  • Frequency of regular maintenance such as coolant changes
What to look for to identify potential problems with your coolant system.
