Description
Product overview
The CSF 3947 is an application-specific replacement radiator. Its construction pairs a aluminum core with plastic tanks. Application: 2017-2019 Ford F-250 Super Duty 6.2L.
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.
