Product Line Details

Gates Molded Heater Hose products are shaped to follow OEM-style hose paths, which helps maintain proper fit in compact engine compartments. This line is built for applications where a straight hose would not match the original routing, including heater and coolant connections on vehicles like the Ford F-150.

Detailed Description

This Gates 12538 molded heater hose is a direct-fit style replacement for the 2015 Ford F-150 valve to heater connection. The molded profile supports the original hose path, while the 0.625-inch inside diameter at both ends and 17.75-inch centerline length provide the dimensions needed for the specified application. Gates 12538 is also listed for coolant, water, and air use, making it a practical service hose for the correct routing and size requirements.

This part cross-references BBB Industries 13538 for the same application.
