Detailed Description

This radiator coolant hose is engineered for 2011-2015 Dodge Durango, lower, and 2011-2015 Jeep Grand Cherokee, lower. The molded profile helps match the original hose routing, while the EPDM material is commonly used in cooling system service for resistance to heat and coolant exposure. If you are replacing a worn lower hose on a Dodge Durango or Jeep Grand Cherokee, Gates 23690 provides a vehicle-specific solution that follows the original application layout.

This part cross-references Bosch 16378 and Continental 66838 for the same application.

Common Problems This Hose Can Address

• Cracked or split lower radiator hose
• Coolant leaks at the hose body
• Softening or swelling from age and heat
• Incorrect hose routing after prior repairs
• Restricted coolant flow caused by a deteriorated hose

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length against the original part before installation. Inspect hose clamps, mating tubes, and nearby cooling system components for wear or corrosion, and replace any damaged sealing surfaces during service. Confirm the hose is positioned correctly on the lower coolant path for the listed vehicle application.
