Gates 20700 Radiator Coolant Hose - Lower or Upper

Gates 20700 Molded Coolant Hose Overview

Gates 20700 is a molded radiator coolant hose built to OEM-quality specifications for upper, lower, bypass, heater, and other coolant routing applications. It uses EPDM construction and a molded shape to match the original hose path on select BMW, Mercedes-Benz, Isuzu, Toyota, Ford, and Mercury vehicles.

The Gates Molded Coolant Hose line is engineered as a direct replacement option for common cooling-system service needs, helping restore proper coolant flow on vehicles such as the BMW 528e, Mercedes-Benz 300D, and Toyota Cressida. Part number 20700 is also listed across multiple aftermarket cross-references for the same application.

Product Details

Gates Molded Coolant Hose 20700 is part of a broad replacement hose line intended to match original coolant hose geometry and specifications. The molded profile helps the hose follow factory routing on vehicles that require a shaped radiator coolant hose rather than a straight universal hose. This makes it a practical replacement for cooling-system service on the BMW 528e upper hose application, Mercedes-Benz 300D lower hose application, and other listed fitments.

This part cross-references Dayco 70705 and Continental 66483 for the same application.

Common Uses

• Replacing a cracked or softened radiator coolant hose
• Restoring coolant circulation after hose swelling or collapse
• Addressing coolant seepage at the hose body or ends
• Correcting fitment issues caused by a non-molded replacement hose
• Servicing cooling and heater hose routing on listed BMW, Mercedes-Benz, Isuzu, Toyota, Ford, and Mercury models

Installation Notes

Verify hose position, end diameters, and centerline length before installation. Confirm the routing matches the original molded hose on the vehicle, especially on applications such as the 1982-1988 BMW 528e, 1979-1985 Mercedes-Benz 300D, and 1978 Toyota Cressida. Inspect clamps, necks, and adjoining cooling-system components for wear before installing the new hose.

Quality Assurance

Gates manufactures this molded coolant hose to OEM-quality specifications for replacement use in radiator and heater hose applications. The molded EPDM construction and application-specific dimensions support accurate fitment on the listed vehicles, including the 1971-1973 Ford Pinto and 1970-1972 Mercury Capri lower hose applications.
