Hot engine coolant circulates through the heater core. When the driver turns on the heat, the blower motor blows air across the heater core and into the cabin.

How often do heater cores need to be replaced?

Most vehicles will never have a problem with the heater core. But if you don't have your cooling system maintained and flushed as part of the car's regular maintenance, the odds of a heater core problem go way up.

How are heater core issues diagnosed?

Heater core diagnosis is as easy as smelling inside the vehicle, and feeling the carpet under the dashboard. The heater core may leak enough coolant onto the carpet to saturate it. If the heater core has not leaked onto the carpet, but the strong smell of coolant is in the vehicle, the heater core is still suspected.
