Cold Weather Is Coming - How's Your Heater Core?

The heater core is a vital part of your car's cooling system. It's essentially a counterpart to a radiator, and it circulates coolant and radiates heat into the cabin to keep you warm. Besides heating, it is also responsible for the functionality of your defrosters. Now that it is finally Fall, you're going to need those two things (heat and defroster) to work well in Auburn, MA.

How Does the Heater Core Work?

Your vehicle's engine warms up while it's running. The coolant absorbs the excess heat and circulates the air away from the engine and through the radiator. But when you turn on the heat, the air gets blown to the heater core to be warmed up. And it makes its way out through the cabin. 

The coolant you add to your car contains anti-corrosive properties that coat the surfaces inside your cooling system, including the heater core. Over time, the coolant becomes less effective and can make your system corroded. If it is left for too long, it can cause a leak within the system. 

What Are the Symptoms of a Heater Core Leak?

  • Your car smells syrupy sweet
  • Your windows get foggy easily
  • Your car is blowing cold air when the heat is on
  • Your vehicle is devouring coolant
  • The engine is hot or the temperature gauge reads hot

The heater core is, most of the time, a maintenance-free part of the car. However, it would be best if you checked the hoses that carry the coolant seasonally. Changing your coolant as directed by your vehicle manufacturer will help ensure your cooling system works properly. Also, spotting leaks early on can help prevent a catastrophic breakdown. If you require any automotive cooling system services, please do not hesitate to call or visit Fuller Automotive today.
