Description
Product overview
The CSF 3953 is an application-specific replacement radiator. Its construction pairs a aluminum core with plastic tanks. Application: Jeep Wrangler JL / Gladiator JT (2.0 / 3.0 / 3.6L).
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.
