Description
Product overview
The CSF 3406 is an application-specific replacement radiator. Its construction pairs a aluminum core with plastic tanks. Application: 2006-2010 Kia Optima 2.4L.
The radiator transfers heat from circulating engine coolant to the air passing through its core. Tube and fin condition, fan operation, and the airflow path all affect the cooling system’s ability to reject heat.
