Product Details

Dayco’s Curved Radiator Hose line is engineered for formed cooling-system routing where a straight hose will not match the vehicle layout. Part Number 73079 is shaped as a branched hose with a 33 1/2-inch trunk height and connection sizes that match the listed application. For Dodge Journey upper radiator hose replacement needs, this hose provides the correct formed profile for the 2009-2019 model years without an oil cooler.

The EPDM material is selected for coolant exposure, while the protective sleeve adds an extra layer where routing or nearby components create abrasion concerns. If you are searching for a 2009 Dodge Journey upper radiator hose, a 2014 Dodge Journey curved coolant hose, or a 2019 Dodge Journey radiator hose replacement, this part number is the direct application match.

Common Problems This Hose Can Address

• Cracked or split upper radiator hose
• Coolant leaks at formed hose bends or branch points
• Softening or swelling from age and heat cycling
• Incorrect hose routing after prior cooling-system repair
• Restricted fitment on vehicles requiring a branched upper hose

Installation Notes and Tips

Verify the vehicle is a 2009-2019 Dodge Journey with no oil cooler before ordering. Match the upper hose routing, branch layout, and connection diameters to the original part before installation. Inspect clamps, mating necks, and nearby components for wear or corrosion so the new hose seals properly once installed.

Quality Assurance

Dayco manufactures this hose to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and dimensional standards for cooling-system service. Part Number 73079 is a direct-fit replacement for the listed Dodge Journey upper radiator hose application.
