Product Details

CSF manufactures a wide range of radiator applications and validates cooling performance through laboratory wind tunnel testing. For Jeep Renegade and Fiat 500X owners, this radiator follows the original layout with plastic end tanks and an aluminum core to match factory-style fitment and cooling path design.

Installation Notes and Tips

Verify inlet and outlet orientation before installation: 1 1/2 in. left inlet and 1 1/2 in. right outlet. Confirm the vehicle uses the listed cross-flow, quick-connect configuration and compare core dimensions to the original radiator before removal. Transfer any required vehicle-specific components from the original assembly if applicable, since cap included is not specified.
