Gates Molded Heater Hose 19171

Key Features
- Factory-molded design follows the original hose path for a precise fit.
- EPDM construction resists heat and coolant exposure in HVAC and cooling-system service.
- Small inside diameter suits compact hose routing in modern engine compartments.
- Suitable for coolant, water, and air applications.
- Approved for marine applications.
Detailed Description
Gates 19171 is a molded heater hose designed as an OEM-style replacement for applications that require a formed hose with a small inside diameter. The 18.4-inch centerline length and 0.63-inch ends support the original routing used in the Toyota Sienna heater circuit, including the valve to intake manifold path with auxiliary heater equipment. Gates 19171 is also identified as a molded coolant hose for use in compact engine compartments where a straight hose would not follow the intended route.
This part cross-references Four Seasons 64165 and Remy 11171 for the same application.
What It Is Used For
- Replacing a cracked or softened heater hose.
- Restoring coolant flow through the heater circuit.
- Correcting hose routing in a tight engine compartment.
- Addressing leaks at a molded hose section.
- Replacing a hose that no longer holds its formed shape.
Installation Notes and Tips
Verify the hose path, end diameters, and centerline length before installation. Match the molded shape to the original routing and confirm the valve to intake manifold application on the Toyota Sienna. Inspect adjoining clamps, fittings, and nearby hoses for wear before reassembly.
Quality Assurance
Gates manufactures this hose as an OEM-style molded replacement for service applications that require a formed coolant hose profile.
