This Continental molded radiator coolant hose is engineered for the lower cooling circuit on 2009-2014 Hyundai Genesis vehicles. The 1.380-inch inside diameter at both ends and 18.500-inch length support a precise OE-style route, while the EPDM construction and synthetic reinforcement are specified for coolant transfer in demanding engine bay conditions. If you are replacing a worn Hyundai Genesis lower radiator hose, Continental 66690 provides the correct molded shape and dimensions for the application.

This part cross-references Gates 24833 for the same application.

Common Problems It Can Address

• Coolant leaks from a cracked or aged lower hose
• Softening, swelling, or collapse of the hose under heat
• Poor hose routing caused by a misshaped replacement part
• Loss of coolant circulation through the lower radiator circuit
• Service replacement for a damaged Hyundai Genesis lower radiator hose

Installation Notes

Verify hose routing against the original part before installation on the Hyundai Genesis. Inspect adjoining clamps, radiator necks, and coolant connections for wear or corrosion, and confirm the hose seats fully at both ends. After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.
