Gates 12157 HVAC Heater Hose - Transmission Oil Cooler Outlet

Gates 12157 Molded Heater Hose Overview

The Gates 12157 Molded Heater Hose is a factory-molded, OEM-style coolant hose built for tighter engine compartments where a straight hose will not route correctly. It is made from EPDM and is suitable for coolant, water, and air service, with marine application approval.

For 2013-2016 Honda Accord models with CVT transmission, this molded hose serves the transmission oil cooler outlet/radiator coolant hose position and follows the original routing for a cleaner, more accurate replacement. Gates 12157 is a practical choice when you need a formed hose that matches the vehicle’s factory layout.

Key Features

• OEM-style molded heater hose for precise routing
• EPDM construction for coolant, water, and air applications
• Small I.D. design for compact engine bay fitment
• Centerline length: 13.67 in. (347 mm)

Detailed Description

Gates Molded Heater Hose 12157 is formed to follow the original hose path in vehicles with limited clearance, helping maintain proper hose alignment and connection geometry. The EPDM material is commonly used in cooling-system service because it handles heat and fluid exposure associated with coolant circuits. In the 2013-2016 Honda Accord, this hose is listed for the transmission oil cooler outlet and radiator coolant hose application on CVT-equipped vehicles.

This part cross-references Carlson 13157 for the same application. If you are sourcing a Gates 12157 replacement for a Honda Accord coolant hose repair, verify the hose shape, end diameters, and routing against the removed part before installation.

What It Helps Address

• Coolant hose leaks at a molded section
• Cracked or hardened hose material from heat cycling
• Poor routing in tight engine compartments
• Incorrect hose fitment after prior repairs
• Transmission oil cooler outlet hose replacement on CVT-equipped Honda Accord models

Installation Notes and Tips

Confirm the hose path, end sizes, and centerline length before installation. Compare the old hose to Gates 12157 to ensure the molded bends and connection points match the vehicle routing. Inspect adjoining clamps, fittings, and mating surfaces for wear or corrosion before reassembly.

For fitment, this part is listed for 2013-2016 Honda Accord, transmission oil cooler outlet. It is also referenced as a radiator coolant hose for vehicles with CVT transmission. Gates 12157 should be installed only where the molded shape and 13 mm end I.D. match the original hose layout.
