Detailed Description

Gates 12250 is a molded heater hose engineered for vehicles that use a formed hose path at the heater outlet. The EPDM construction supports heat and coolant exposure, while the molded profile helps match the original routing used in compact engine compartments. This makes it a practical replacement for Kia Forte, Forte5, Forte Koup, and Soul applications listed below.

As part of the Gates Molded Heater Hose line, this hose is built around OE-style geometry rather than universal straight-hose routing. That matters when replacing a heater outlet hose on a 2015-2018 Kia Forte, 2015-2018 Kia Forte5, 2015-2017 Kia Forte Koup, or 2017 Kia Soul. This part cross-references BBB Industries 13250 for the same application.

Installation Notes

Verify end diameters and centerline length before installation to confirm the hose matches the original routing. Inspect adjoining heater pipes, clamps, and connection points for wear or corrosion before installing the new hose. Because this is a molded hose, align it to the factory path during installation to avoid twist or stress at the connections.

The EPDM material and molded construction support dependable service in coolant-system use, including the listed Kia Forte and Kia Soul heater outlet applications.
