Detailed Description

Gates 19104 is a molded coolant and heater hose formed to match the routing demands of modern, compact engine compartments. Its EPDM material and molded profile help it follow the original hose path on vehicles that use a tight HVAC heater hose layout. This part number is listed for 2001 Ford Ranger and 2001 Mazda B2500 valve-to-thermostat applications, 2000 Ford F-100 Ranger and 2000 Ford Ranger valve-to-intake-manifold applications, 1999-2000 Mazda B2500 valve-to-intake-manifold applications, and 1995-1997 Lincoln Continental heater-to-pipe-1 applications. The Gates 19104 hose is a practical OE-style replacement when the original molded hose has aged, softened, or lost its formed shape.

This part cross-references Carlson 19104 and Remy 11104 for the same application.

What It Helps Address

• Coolant leaks from a cracked or deteriorated heater hose
• Improper hose routing in a tight engine bay
• Softening, swelling, or collapse of an aging EPDM hose
• Loss of factory-shaped fit on molded HVAC hose runs
• Service replacement for select Ford Ranger, Mazda B2500, and Lincoln Continental heater circuits

Installation Notes and Tips

Verify the vehicle’s hose routing, connection points, and position before installation. Confirm the application by year, make, model, and hose location, especially on Ford Ranger and Mazda B2500 vehicles with A/C and serpentine belt configurations. Inspect mating tubes and clamps for wear or corrosion before installing the new hose. Because this is a molded hose, correct orientation matters for proper fit.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement part for HVAC coolant routing. The EPDM construction and factory-molded shape are selected to match the demands of compact engine compartments and the listed vehicle applications.
