Gates 20661 Radiator Coolant Hose

Gates 20661 Molded Coolant Hose

Gates 20661 is a molded radiator coolant hose built to OEM-quality specifications for upper, lower, bypass, and heater-style coolant routing. Made from EPDM, it provides a formed replacement for vehicles that need a precise hose shape instead of a universal cut-to-fit part.

The Gates Molded Coolant Hose line covers a wide range of radiator and HVAC coolant applications, helping simplify radiator hose replacement on vehicles such as the Suzuki XL-7, Suzuki Grand Vitara, and Chevrolet Tracker.

Key Features

• EPDM construction for coolant-system service
• Molded shape for direct routing and proper fit
• 1.25 in. inside diameter at both ends
• 11.4 in. centerline length
• No spring and no quick-connect fittings
• Built for radiator and HVAC compatible coolant and heater hose applications

Detailed Description

This Gates molded coolant hose, part number 20661, is formed to match specific coolant routing needs across a broad range of vehicles. It is listed for upper, lower, thermostat, water pump, and heater-related positions, including applications on the Suzuki XL-7, Suzuki Grand Vitara, Chevrolet Tracker, Ford Taurus, Mazda Miata, and Nissan Altima. The molded design helps maintain the intended hose path where a straight hose would not provide the correct bend or clearance.

Gates Molded Coolant Hose products are engineered as OE-style replacements for radiator hose service, giving technicians a direct-fit option for many older and late-model vehicles. This part cross-references Four Seasons 20661 for the same application.

What It Helps Address

• Cracked or swollen radiator coolant hose
• Collapsed hose routing at formed bends
• Coolant leaks at upper or lower hose connections
• Heat-related hose deterioration in the cooling system
• Incorrect fit from a universal hose replacement

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. This hose is molded and should be matched to the listed position, such as upper, lower, thermostat to pipe, or water pump to pipe applications. Check clamps, mating tubes, and thermostat housing surfaces for wear or corrosion before installing the replacement hose.

Fitment examples include 2002-2006 Suzuki XL-7 upper, 1999-2005 Suzuki Grand Vitara upper, 2001-2004 Chevrolet Tracker upper, 1993-2001 Nissan Altima thermostat to pipe, and 1996-2000 Ford Taurus water pump to pipe-4.

Quality Assurance

Gates manufactures this molded coolant hose to OEM-quality specifications for cooling-system service. The EPDM construction and formed profile support consistent replacement fitment across the listed applications, including vehicles that require a shaped hose for proper radiator and HVAC coolant routing.
