Restore warm, defrosted cabin air with the Agility Auto Parts HVAC Heater Core, MPN 9010615. It installs as a direct-fit replacement for the 2006-2010 Kia Magentis [All] and 2006-2010 Kia Optima [All]. The heater core is the small radiator inside the HVAC module: engine coolant flows through its tubes while the blower pushes cabin air across the fins to warm the interior and help defog the glass. Signs the original may need replacing include weak or no heat, a sweet coolant smell inside the cabin, fogging on the windshield, or coolant residue on the passenger-side floor.
