Heater Core

The heater core takes hot coolant from the vehicle's engine and uses it to generate warmth for your car's interior.

Common symptoms of a bad heater core include the odor of antifreeze when the heater is running, windshield fogging or a lack of warm air.

Over time corrosion and clogging can make heat exchange less effective, meaning a cold car on a cold day.

Replace your heater core before it leaves you out in the cold
