Gates 19310 HVAC Heater Hose - Engine To Heater or Heater Inlet

Gates Molded Heater Hose for Hyundai Cooling Systems

The Gates 19310 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. It is formed to match factory-style bends and is made from EPDM for use in coolant, water, and air applications.

Compatible with select Hyundai Elantra and Hyundai Tiburon applications, this molded heater hose supports heater circuit routing in engine-to-heater and heater inlet locations. The Gates Molded Heater Hose line is focused on factory-shaped replacement hoses for modern vehicles with compact packaging.

Detailed Description

Gates 19310 is a molded HVAC heater hose designed to replace factory-formed coolant hose routing in vehicles that require a shaped hose rather than a universal straight section. The 0.66-inch inside diameter at both ends and 18.6-inch centerline length help match the original path through the engine bay. This hose is built from EPDM, a common material for cooling-system service, and is suitable for coolant, water, and air transfer. The Gates 19310 is a direct-fit style solution for Hyundai Elantra and Hyundai Tiburon heater hose routing where the original hose follows a molded path.

This part cross-references BBB Industries 11310 for the same application.

• Need for an OE-style molded replacement on Hyundai cooling systems

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length against the original part before installation. Because this is a molded hose, correct orientation matters for proper fit in the engine bay. Inspect adjoining clamps, fittings, and heater connections for wear or corrosion before reassembly.

Quality Assurance

Gates manufactures molded coolant hoses to OE-style dimensions and material standards for service replacement use. The 19310 is built for factory-style fitment in supported Hyundai applications and marine-approved service environments.
