Product Details

Gates 12158 is a molded coolant hose made to follow OEM-style routing where a straight hose will not fit cleanly. The molded profile helps maintain the correct path in tighter spaces, which is especially relevant for 2013-2016 Honda Accord models with CVT transmission notes at the transmission oil cooler inlet. This Gates molded heater hose is also identified for radiator coolant hose service in that application, making it a practical replacement when the original hose has aged, softened, or developed leaks.

The Gates Molded Heater Hose product line focuses on factory-shaped hoses for modern vehicles with limited clearance. For Honda Accord owners searching for a molded heater hose, coolant hose, or transmission oil cooler inlet hose, part number 12158 provides the specified 0.5-inch ends and 11.87-inch centerline length needed for the listed fitment.

This part cross-references Carlson 13158 for the same application.

Used For

• Coolant seepage at a molded hose section
• Cracking, hardening, or swelling in the original hose
• Incorrect hose routing in a tight engine compartment
• Replacement of a worn radiator coolant hose on select Honda Accord models
• Service at the transmission oil cooler inlet on listed vehicles

Installation Notes

Verify hose routing, end size, and centerline length before installation. This hose is molded, so align it to the factory path rather than forcing a straight installation. Inspect adjoining clamps, fittings, and mating surfaces for wear or corrosion before reassembly. Confirm the vehicle is a 2013-2016 Honda Accord with the listed CVT-related application before ordering or installing Gates 12158.

Quality Assurance

Gates manufactures this hose as an OEM-style molded replacement for coolant-system service. The EPDM material and factory-molded construction support consistent fitment in the specified Honda Accord application.
