The OSC 98459 heater core circulates hot engine coolant through its aluminum fins, allowing the blower motor to push warm air into the cabin for heating and defrost functions. OSC's rigorous cycle and burst testing programs ensure this core is built to withstand real-world driving conditions including potholes, vibration, and high-mileage use. This is a brand-new unit — not remanufactured.
