Detailed Product Description

Gates 20611 is a molded radiator coolant hose with a 2-inch inside diameter at each end and a 16.9-inch centerline length. The EPDM rubber construction is suited to cooling-system temperatures and coolant exposure, while the internal spring helps maintain hose shape in lower hose applications where collapse resistance matters. This part number is commonly searched for Ford F-100, Ford F-150, Ford F-250, and Ford F-350 lower radiator hose replacement needs, as well as 2003 Dodge Ram 2500 and Ram 3500 lower hose service.

This part cross-references Continental 60408 and Dayco 70212 for the same application.

Common Problems This Hose Can Address

• Cracked or aged lower radiator hose
• Coolant leaks at the hose body
• Softening or swelling from heat and coolant exposure
• Hose collapse under cooling-system vacuum conditions
• Poor fit from a universal hose used in a molded application

Installation Notes and Tips

• Verify the hose routing, end diameters, and centerline length before installation.
• Inspect hose clamps, radiator necks, and adjoining pipes for wear or corrosion.
• Drain coolant safely before removing the existing hose.
