Heater Core

A car Heater Core is a component of a vehicle’s heater system.
The common signs of a faulty car Heater Core include lack of heat, foggy windows, a sweet smell inside the vehicle, and coolant leaking inside the vehicle.
The main function of a car Heater Core is to provide heat to the passenger compartment of the vehicle by using hot coolant from the engine.
Hot engine coolant from the engine flows through the Heater Core, which is located in the dashboard. Air from the blower motor passes through the Heater Core, and the heat from the hot coolant is transferred to the air, which is then blown into the passenger compartment.
