Detailed Description

Built as an engine coolant bypass hose, Gates 12514 is formed to match the routing needs of vehicles that use a molded heater hose rather than a straight universal hose. The EPDM construction supports coolant transfer and helps maintain a proper seal at the connection points, while the molded profile helps the hose follow the intended path in confined engine compartments. This part cross-references Bosch 13514 for the same application.

Installation Notes and Tips

Verify end diameters and centerline length against the removed hose before installation. Inspect adjoining fittings, clamps, and nearby coolant passages for wear or corrosion, and confirm the hose follows the original routing without twist or kinking. After installation, refill and bleed the cooling system according to the vehicle service procedure.
