Gates 19111 HVAC Heater Hose

Gates Molded Heater Hose 19111

The Gates 19111 molded heater hose is a factory-shaped coolant hose built for tight engine bays and OE-style routing. It is made from EPDM and uses a small 0.63 in. inside diameter at both ends with a 34.5 in. centerline length for a precise replacement path.

Compatible with select Toyota Hilux, Toyota Tacoma, Toyota 4Runner, Chevrolet Equinox, and Pontiac Torrent applications, this molded heater hose is also suitable for coolant, water, and air service. The Gates Molded Heater Hose line focuses on factory-molded routing for vehicles where straight hose sections do not follow the original path cleanly.

Detailed Description

Gates 19111 is a molded HVAC heater hose engineered for vehicles that require a formed hose to maintain proper routing around compact components. Its molded profile helps match original hose geometry in smaller, tighter-fitting engine compartments, reducing the need to force a straight hose into a curved path. This part number 19111 is a direct-fit style solution for applications such as Toyota Tacoma heater-to-tee routing, Toyota 4Runner pipe-to-heater routing, and select Chevrolet Equinox and Pontiac Torrent reservoir connections.

This hose is built from EPDM, a common material used in cooling-system service for its resistance to heat and coolant exposure. The 16 mm end size and 876 mm centerline length make it important to verify the original hose shape and routing before installation. This part cross-references Carlson 19111 for the same application.

What It Helps Solve

• Cracked or leaking heater hose sections
• Incorrect hose routing in tight engine compartments
• Loss of heater flow caused by deteriorated coolant hose material
• Replacement needs for molded coolant or heater hose paths
• Service issues on Toyota Tacoma, Toyota 4Runner, and Toyota Hilux heater circuits

Installation Notes and Tips

• Confirm the original hose shape, end size, and centerline length before installation.
• Use the vehicle routing shown in the fitment data for Toyota Hilux, Toyota Tacoma, Toyota 4Runner, Chevrolet Equinox, and Pontiac Torrent applications.
• Check for auxiliary heater equipment, since some listed applications use different routing notes.
• Inspect adjoining pipes, tees, and clamps for wear before installing the new hose.
• Verify coolant level and bleed the system after service.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement built to factory-molded dimensions for the listed applications. The design supports consistent fitment in compact engine layouts and is approved for marine applications.
