Too Afraid to Ask

The heater core is like a tiny radiator inside your car that takes hot liquid from the engine and uses it to warm the air you breathe in the cabin. If it leaks, your car can get cold and wet.

Technical Definition

The heater core is a small radiator-like component that transfers heat from the engine coolant to the air blown into the passenger compartment. It is essential for cabin heating and can be a common source of leaks.
