Product Details

Gates Molded Coolant Hose line is engineered for upper, lower, bypass, heater, and other coolant applications using OEM-style specifications. Part number 21840 is a molded EPDM radiator coolant hose that follows the original routing needed for select Ford Taurus, Lincoln Continental, and Mercury Sable cooling-system layouts. This makes it a practical choice when replacing a worn or leaking hose on vehicles that require a formed hose shape rather than a universal straight hose. This part cross-references Dayco 71414 for the same application.

What It Helps Fix

• Coolant leaks from cracked or aged hose material
• Improper hose routing caused by a collapsed or misshaped hose
• Overheating related to restricted coolant flow
• Soft spots, swelling, or deterioration in the radiator hose
• Fitment issues when replacing a molded hose with the correct formed profile

Installation Notes

Verify the hose shape, end diameters, and centerline length against the original part before installation. Inspect mating necks, clamps, and nearby cooling-system components for wear or corrosion, and replace any damaged parts as needed. Confirm the vehicle application by year, make, model, and position before service. Fits 1990 Ford Taurus, intake manifold to water pump. Fits 1988-1990 Lincoln Continental, front. Fits 1988-1990 Mercury Sable, front. Fits 1988-1989 Ford Taurus, front.
