Continental 66172 Radiator Coolant Hose - Lower

Continental Lower Radiator Coolant Hose

Continental 66172 is a molded radiator coolant hose built for lower cooling-system routing on select Ford and Lincoln trucks and SUVs. It uses an EPDM tube and cover with synthetic reinforcement to meet or exceed SAE 20R4EC Class D1 requirements, and its exact OEM-style configuration supports a precise replacement fit.

The Continental Molded line focuses on OE-shaped coolant hoses for direct replacement service. This hose follows the original routing and dimensions needed for lower radiator applications on vehicles such as the Ford Expedition, Lincoln Navigator, and Ford F-150.

What It Helps Repair

• Coolant leaks from a cracked or aged lower radiator hose
• Softening, swelling, or collapse in the coolant line
• Restricted coolant flow caused by hose deterioration
• Overheating concerns tied to a damaged radiator hose
• Improper fit from a non-molded replacement hose

Installation Notes

Verify hose routing, inside diameter, and molded shape against the original part before installation. Inspect adjoining clamps, radiator necks, and engine fittings for wear or corrosion so the new hose seals correctly. Confirm the lower hose path matches the vehicle application before filling and bleeding the cooling system.

Quality Assurance

Built to meet or exceed SAE 20R4EC Class D1 specifications, this hose is engineered for coolant transfer in the vehicle’s cooling system and follows an exact OEM configuration for fitment accuracy.
