Gates 19535 HVAC Heater Hose

Gates Molded Heater Hose for Subaru Cooling Systems

The Gates 19535 molded heater hose is an OEM-style coolant hose built for tight engine bays and factory routing. It is shaped to match the original path in Subaru and Saab applications, helping maintain proper coolant flow through the heater circuit.

Made from EPDM and factory-molded for a precise fit, this Gates Molded Heater Hose is approved for coolant, water, air, and marine applications. The small 0.63 in. inside diameter and 4.9 in. centerline length support direct replacement use where the original hose follows a formed bend.

Key Features

• Gates Molded Heater Hose, part number 19535
• OEM-style molded construction for compact engine compartments
• EPDM material for coolant, water, and air service
• 0.63 in. inside diameter at both ends
• 4.9 in. centerline length for formed routing
• Approved for marine applications
• Direct-fit replacement for select Subaru and Saab heater hose routes

Product Details

This molded heater hose is built for vehicles that use a shaped coolant line between the water pump, pipe, and thermostat connections. It is a strong match for Subaru Forester, Subaru Impreza, Subaru Legacy, Subaru Outback, Subaru Baja, and Saab 9-2X applications where the hose must follow the original factory bend. The Gates 19535 helps restore proper coolant transfer in the heater circuit without forcing a universal hose into a tight routing path.

This part cross-references Dayco 87964 for the same application.

Installation Notes

Verify the hose routing, end diameters, and centerline length against the original part before installation. Because this hose is molded for specific Subaru cooling-system paths, correct orientation matters for a proper seal and smooth routing around nearby components.

Inspect adjoining pipes, clamps, thermostat housing, and water pump connections for wear or corrosion before installing the replacement hose. Confirm the vehicle’s exact year, make, model, and hose position, especially on Subaru Forester, Subaru Impreza, and Subaru Legacy applications.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement built to factory-form specifications. The EPDM construction and molded shape support consistent fitment in the listed cooling-system applications.
