Detailed Description

Dayco 72937 is a curved radiator coolant hose engineered for upper hose applications where the factory routing requires a formed bend. The EPDM rubber construction is suited for coolant exposure and everyday engine bay temperatures, while the single I.D. design and matched end diameters support a secure connection at both ends. This hose is specified for 2014-2020 Kia Sorento, upper, and 2013-2016 Hyundai Santa Fe Sport, upper. For buyers searching for a 2014-2020 Kia Sorento upper radiator hose or a 2013-2016 Hyundai Santa Fe Sport upper coolant hose, Dayco 72937 provides the correct fitment profile.

The Dayco curved radiator hose line focuses on formed replacement hoses that follow OE-style routing and dimensions. That makes the Dayco 72937 a practical choice when replacing a worn, cracked, or softened upper hose on the Kia Sorento or Hyundai Santa Fe Sport cooling system.

What It Helps Address

• Coolant leaks from a cracked or deteriorated upper radiator hose
• Softening, swelling, or collapse in the factory hose
• Improper hose routing after a previous replacement
• Loss of cooling-system sealing at the hose ends

Installation Notes and Tips

Verify the vehicle year, model, and upper hose routing before installation. Inspect hose clamps, radiator necks, and engine-side fittings for wear or corrosion before transferring the new hose into place. Confirm that the hose follows the original curved path without twisting, and check coolant level and system pressure after installation. Fits 2014-2020 Kia Sorento, upper.
