Gates 12394 HVAC Heater Hose - Reservoir To Radiator

Gates 12394 Molded Heater Hose

Gates 12394 is a factory-molded heater hose built for tight engine bays where a straight hose will not follow the original routing. Made from EPDM, it is specified for coolant, water, and air service, and it is also approved for marine applications.

This molded coolant hose is shaped for reservoir-to-radiator routing on select Ford and Lincoln applications, including Ford F-150, Ford Expedition, Lincoln Navigator, and Lincoln Mark LT coverage.

Detailed Description

Gates 12394 is part of the Molded Heater Hose line, a product line focused on OE-style hose shapes for modern vehicles with compact engine packaging. The molded form helps the hose follow the original path without forcing bends that can stress the cooling system. For buyers searching for a Ford F-150 reservoir to radiator molded heater hose or a Lincoln Navigator molded coolant hose, this part number provides a direct replacement-style solution.

This part cross-references Bosch 13394 for the same application. It also aligns with OE reference numbers BL3Z 8075 A and BL34 8W005 AA.

What It Helps Address

• Cracked or deteriorated heater hose material
• Incorrect hose routing in tight engine compartments
• Coolant leaks at a molded hose section
• Heat-related hose collapse or deformation
• Replacement needs for reservoir-to-radiator hose routing on Ford and Lincoln trucks and SUVs

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Match the molded shape to the original path so the hose does not twist or rub against nearby components. Confirm vehicle application by year, make, model, and reservoir-to-radiator position before ordering Gates 12394.
