Detailed Product Description

Gates 18526 is a molded heater hose engineered for vehicles that require a compact, pre-formed hose path rather than a universal straight hose. Its 0.63-inch inside diameter at both ends and 19.7-inch centerline length support factory-style routing in confined engine compartments. For drivers and technicians servicing a 2007-2009 Kia Spectra or 2007-2009 Kia Spectra5, this hose provides a direct-fit solution for the heater inlet connection.

This part cross-references CSF 10526 for the same application.

Common Problems This Hose Can Address

• Cracked or hardened heater hose material
• Coolant seepage at a worn hose section
• Poor hose routing in tight engine compartments
• Heat-related hose deformation
• Replacement needs for heater inlet service on Kia Spectra and Kia Spectra5 models

Installation Notes and Tips

Verify hose routing, end diameter, and centerline length against the original part before installation. Inspect adjoining clamps, fittings, and nearby coolant passages for wear or corrosion, and confirm the hose is seated correctly at the heater inlet connection. Proper routing helps prevent kinks and contact with hot or moving components.

Quality Assurance

Gates Molded Heater Hose products are built to OE-style dimensions and formed for factory-like fitment in modern compact engine bays. Part number 18526 is intended for direct replacement service on the listed Kia applications.
