Detailed Description

Gates 51341 is a molded HVAC heater hose engineered for select 2011-2014 Ford F-150 and 2012-2014 Lincoln Mark LT models in the reservoir-to-pipe position. The hose follows the factory routing and incorporates a female quick connector, matching the style used in the original coolant hose assembly. If you are replacing a worn or damaged Ford F-150 heater hose or a Lincoln Mark LT molded coolant hose, this part number provides a direct-fit service solution for the specified applications.

This part cross-references Monroe Shocks & Struts (e.g., 22958M, BL3Z 8C350 A) for the same application.

What It Helps Address

• Coolant leaks from a cracked or deteriorated hose
• Loose or damaged quick-connect hose attachment
• Incorrect hose routing after prior repair work
• Heat-related hose hardening or swelling
• Loss of proper coolant flow through the reservoir-to-pipe line

Installation Notes and Tips

Verify the vehicle year, make, model, and reservoir-to-pipe routing before installation. Inspect the mating pipe, connector, and surrounding cooling system components for wear, contamination, or damage before transferring the hose into service. Confirm the quick connector seats fully and that the hose follows the original molded path without twist or tension.
