The heater core is a small radiator located inside the HVAC unit that uses hot engine coolant to warm the air blown into the cabin. It is essential for passenger comfort and windshield defogging. A leaking core can result in loss of cabin heat, a sweet smell inside the car, and fogged windows. We supply durable heater cores engineered for efficient heat transfer and reliable, leak-free operation. Our cores ensure a consistent and ample supply of warm air to the vehicle's interior, delivering crucial comfort and safety through effective defrosting and heating capabilities.
