Product Details

Dayco’s Curved Radiator Hose line focuses on replacement coolant hoses shaped for specific vehicle routing and connection points. This Dayco 72938 hose is formed for lower radiator service and uses EPDM material to handle coolant exposure in the engine cooling circuit.

Drain the cooling system as needed, then confirm the hose seats fully at both ends and follows the original curved path without twisting.

For fitment reference, this hose fits 2014-2020 Kia Sorento, lower, and 2013-2016 Hyundai Santa Fe Sport, lower. Confirm the vehicle’s cooling-system layout against the listed application before service.
