Gates 18598 HVAC Heater Hose - Heater Outlet

Gates 18598 Molded Heater Hose Overview

The Gates 18598 molded heater hose is an OEM-style coolant hose built for tight engine bays and heater outlet routing. Its factory-molded shape helps maintain proper hose routing in compact applications, including select Hyundai Accent, Kia Rio, Kia Rio5, and Dodge Attitude models.

Made from EPDM, this Gates Molded Heater Hose is suitable for coolant, water, and air service, and it is also approved for marine applications. The 13.5-inch centerline length and 19 mm inside diameter at both ends support a direct-fit style replacement where the original hose follows a formed path.

Detailed Description

Gates Molded Heater Hose 18598 is built for vehicles that use a formed heater hose path rather than a straight universal hose. The molded profile helps match the original routing in compact HVAC and cooling system layouts, which is important in applications such as the 2012-2017 Hyundai Accent heater outlet, the 2010-2017 Kia Rio heater outlet, the 2012-2014 Dodge Attitude heater outlet, and the 2010-2011 Kia Rio5 heater outlet. If you are replacing a worn or damaged hose on a Hyundai Accent, Kia Rio, or Kia Rio5, this formed hose provides the correct shape for the intended connection point.

This Gates 18598 hose cross-references ACI 88523 and SKF 10598 for the same application.

Common Uses

• Replacing a cracked or leaking heater outlet hose
• Restoring coolant flow through the heater circuit
• Correcting hose routing in tight engine compartments
• Addressing soft, swollen, or heat-aged EPDM hose material
• Repairing a formed hose that no longer holds its original shape

Installation Notes and Tips

Verify end diameter, centerline length, and molded routing against the original hose before installation. Confirm the heater outlet connection point and inspect adjoining clamps, fittings, and nearby hoses for wear. For best results, transfer the hose only after the cooling system has been safely drained and the engine has cooled.

Quality Assurance

Gates manufactures this molded heater hose as an OEM-style replacement part for formed coolant routing in compact engine compartments. The EPDM construction and molded design support consistent fitment for the listed Hyundai Accent, Kia Rio, Kia Rio5, and Dodge Attitude applications.
