Gates 28475 HVAC Heater Hose

Gates 90 Degree Molded Heater Hose 28475

The Gates 90 Degree Molded Heater Hose 28475 is built for heater and coolant routing where a sharp bend is required. With a 90-degree molded shape and 3/4 in. inside diameter at both ends, it provides a direct replacement for many HVAC heater hose and coolant hose applications across a wide range of vehicles.

Made from EPDM, this molded heater hose is intended for radiator and HVAC coolant routing in vehicles that need a formed hose to clear nearby components. Gates offers this line in multiple sizes to cover many replacement needs, and part number 28475 is one of the common OE-style solutions for formed hose applications.

Key Features

• 90-degree molded heater hose for sharp-bend routing
• EPDM construction for coolant and heater hose service
• 3/4 in. inside diameter on both ends
• 16 in. centerline length with 4 in. and 12 in. arm lengths
• Formed replacement for HVAC heater hose and coolant hose layouts
• Direct-fit style for many reservoir, thermostat, pipe, and engine connections

Product Details

Gates 28475 is a molded HVAC heater hose built to replace hoses that must turn tightly without kinking or collapsing. The 90-degree shape helps maintain proper coolant flow in formed routing paths, including reservoir-to-thermostat, pipe-to-engine, and heater-to-pipe applications. This makes it a practical choice for service work on vehicles such as Buick Regal, Cadillac CTS, and Chevrolet Malibu, where formed hose routing is part of the original system layout.

This part cross-references Dayco 70023 and Continental 63912 for the same application.

Common Problems This Hose Can Address

• Cracked or leaking molded heater hose
• Kinked hose caused by a tight bend in the cooling system
• Restricted coolant flow through a collapsed rubber hose
• Improper routing after heater hose replacement
• Fitment issues when a straight hose cannot follow the original path

Installation Notes and Tips

• Verify inside diameter, centerline length, and arm lengths before installation.
• Match the original hose routing and connection points exactly.
• Inspect adjoining pipes, clamps, and fittings for wear or corrosion before reuse.
• Confirm clearance around the hose so the 90-degree bend does not rub against nearby components.
• Use the vehicle-specific fitment list to confirm the correct application for your year, make, model, and position.

Quality Assurance

Gates manufactures this molded heater hose as part of its 90 Degree Molded Heater Hose line, which is built to cover thousands of formed-hose applications. The EPDM construction and molded shape support reliable coolant and HVAC hose replacement where the original routing requires a sharp bend.
