Gates 12384 HVAC Heater Hose - Heater

Gates Molded Heater Hose for Tight Engine Bays

The Gates Molded Heater Hose, part number 12384, is a factory-molded coolant hose built for compact engine compartments where a straight hose will not route correctly. It is made from EPDM and is approved for coolant, water, air, and marine applications.

Compatible with 2009-2010 Dodge Journey heater applications with rear heater routing, this molded hose follows the OE-style shape needed for proper fitment in confined spaces. The Gates 12384 is also cross-referenced to BBB Industries 12384 and 13384, as well as F10604 for the same application.

Product Details

Gates Molded Heater Hose 12384 is shaped to match the routing demands of modern vehicles with limited clearance around the engine. The molded profile helps maintain a clean hose path for heater and coolant circulation, while the EPDM material is suited for thermal and fluid exposure in HVAC and cooling system service. For 2009-2010 Dodge Journey heater repairs, this hose supports rear heater configurations where correct bend geometry matters. If you are replacing a worn or leaking molded heater hose on a Dodge Journey, part number 12384 provides the OE-style form needed for a direct routing match.

• Fixing routing issues caused by a straight hose in a tight bay
• Addressing hose collapse or deformation from age and heat

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. Match the molded shape to the original path on the vehicle and inspect adjoining clamps, fittings, and heater connections for wear or corrosion. For 2009-2010 Dodge Journey heater service, confirm rear heater configuration and compare the removed hose to Gates 12384 before final assembly.
