What is a heater core?

Posted on 12/27/2019


Your heater core is part of your cooling and heating system. The coolant/antifreeze that flows through your engine to keep it cooled properly also flows through your heater core. The heater core provides heat to the interior of your car through the antifreeze that flows through your engine. Have you ever noticed that your heater doesn't blow hot until your engine is warm - that is why. 



Give us a call and let us take care of you.
