What This Radiator Helps Address

  • Overheating caused by a leaking or restricted radiator
  • Coolant loss from cracked tanks or damaged core seams
  • Reduced heat transfer from an aging radiator core
  • Cooling system service needs on a Kia Sportage with OE-style fitment
  • Oil cooler replacement needs when the original unit is no longer performing properly

Installation Notes and Tips

Verify core dimensions, inlet and outlet orientation, and oil cooler configuration before installation. Confirm the vehicle is a 2017-2021 Kia Sportage or 2022 Kia Sportage, since the 2022 application is listed separately with upgraded higher-performance and stronger B-tube design notes. Transfer any required components from the original cooling system as needed, and inspect hoses, clamps, and coolant condition during radiator replacement.

Quality Assurance

CSF supplies OE-style cooling components, and this radiator follows an aluminum-core, plastic-tank construction intended to match the original application layout for the Kia Sportage.
