Installation Notes and Tips
Verify inlet and outlet orientation before installation: inlet is on the right and outlet is on the left. Confirm radiator dimensions, hose routing, and oil cooler connections against the original unit before assembly. The cap is not included, so reuse or replace the correct cap separately if needed. For best results, inspect hoses, clamps, and coolant condition during radiator replacement on the Kia Sedona.
