- 1.750-inch inside diameter at both ends
- 18.700-inch overall length
Product Details
Continental Molded 66839 is a radiator coolant hose designed to transfer glycol-based coolant throughout the cooling system. The molded shape follows the original equipment layout, helping maintain correct hose routing on the lower side of the radiator circuit. This part cross-references Gates 23689 for the same application.
Compatible With 2011-2020 Jeep Grand Cherokee, lower; 2011-2012 Dodge Durango, lower; and 2013-2020 Dodge Durango, lower without oil cooler. The fitment coverage makes this hose a direct replacement option for common lower hose service on these vehicles.
Common Replacement Reasons
- Cracked or split lower radiator hose
- Coolant seepage at the hose body or ends
- Softening, swelling, or collapse from heat cycling
- Incorrect hose shape after prior repair
- Loss of proper coolant flow in the lower cooling circuit
Installation Notes
Verify hose routing, end diameter, and vehicle configuration before installation. This application is molded and must match the original lower hose path, especially on 2013-2020 Dodge Durango models without oil cooler. Inspect adjoining clamps, radiator necks, and coolant connections for wear or corrosion before installing the new hose.
Quality Assurance
Continental designs this molded hose to OE configuration and material standards for dependable cooling-system service. The EPDM construction and synthetic reinforcement are specified to meet or exceed SAE 20R4EC Class D1 requirements.
