Product Details

Gates part number 12440 is a molded heater hose engineered for the throttle body inlet on the 2014-2018 Nissan Rogue. Its factory-shaped profile helps match the original hose routing in tighter engine compartments, while the EPDM material supports coolant, water, and air transfer in HVAC and engine cooling applications. If you are replacing a worn Nissan Rogue heater hose or restoring the original hose path, this molded hose provides the correct shape and size for the listed application. This part cross-references 13440 and F10617 for the same application.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged molded hose
• Softening, swelling, or collapse in the original hose
• Poor hose routing after a previous repair
• Loss of heater or coolant flow at the throttle body inlet
• Fitment issues caused by using a straight hose in a molded application

Installation Notes and Tips

Verify the hose routing against the original part before installation. Confirm the 8 mm inside diameter at both ends and the 279 mm centerline length match the vehicle’s throttle body inlet layout. Inspect adjoining clamps, fittings, and connection points for wear or corrosion before installing the new hose on your Nissan Rogue.
