CSF OEM Plastic Radiator - 1985-1988 Toyota 4Runner 2.4L

Product overview

The CSF 2306 is an application-specific replacement radiator. Its construction pairs a copper core with brass tanks.

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.
