Gates Molded Heater Hose for Honda Civic

• EPDM construction for coolant, water, and air service
• Small inside diameters: 16 mm (.62 in) and 19 mm (.75 in)

Product Details

This Gates Molded Heater Hose, part number 12229, is built for the heater outlet position on 2006-2011 Honda Civic models. The molded shape helps match the original hose path in compact engine compartments, where straight hose sections can be difficult to route cleanly. Gates 12229 is also suitable for coolant, water, and air applications, and the EPDM material is selected for common underhood fluid transfer use.

The Molded Heater Hose product line focuses on factory-formed replacement hoses that follow OE-style contours. For Honda Civic heater hose service, that means a hose shaped to support the original routing rather than forcing a universal bend. This helps maintain proper fitment in tighter engine layouts while keeping the installation close to the factory configuration.

This part cross-references BBB Industries 13229 for the same application.

Common Problems It Can Help Address

• Cracked or deteriorated heater hose at the outlet connection
• Coolant seepage from an aged molded hose
• Poor hose routing in a tight engine compartment
• Heat-related hose hardening or softening over time
• Replacement needs during Honda Civic cooling system service

Installation Notes and Tips

Verify the hose routing and end diameters before installation. This Gates 12229 hose is listed for the heater outlet position on 2006-2011 Honda Civic models, so confirm the original hose shape matches the molded profile before removal. Inspect adjoining clamps, fittings, and nearby cooling system components for wear or corrosion during service.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement part for precise fitment in compact engine compartments. The EPDM construction and factory-molded profile support consistent service in coolant, water, air, and marine applications.
