Product Details

The Gates Molded Coolant Hose line is built for replacement service where a formed hose is required to follow the original coolant path. Part number 20605 is a molded hose with equal 15 mm end diameters and a 6.5-inch centerline length, making it a practical choice for restoring coolant flow in vehicles that use a shaped hose rather than a straight section. This Gates 20605 hose is listed for applications including 1994-1996 Toyota Camry, 1996-1997 Toyota RAV4, 1987-1989 Toyota Celica, and 1988 Toyota Tercel, along with select Buick models such as LeSabre, Riviera, Century, Regal, and Skylark.

This part cross-references Dayco 70620 and Continental 63681 for the same application.

Common Repair Uses

• Replacing a cracked or heat-aged radiator coolant hose
• Restoring heater circuit coolant flow
• Correcting coolant leaks at a molded hose section
• Replacing a hose that no longer holds its original shape
• Servicing cooling-system routing on Toyota Camry, Toyota RAV4, and Toyota Celica applications

Installation Notes

Verify end diameter, centerline length, and hose routing against the original part before installation. Inspect adjoining necks, clamps, and coolant passages for wear or corrosion, and confirm the hose follows the factory path without twisting. For fitment-specific service, use the vehicle listing for your exact year and model, such as 1994-1996 Toyota Camry, 1996-1997 Toyota RAV4, or 1987-1989 Toyota Celica.
