Gates 19734 HVAC Heater Hose

Gates Molded Heater Hose 19734 Overview

Gates 19734 is a molded heater hose built for tight engine bays where a straight hose will not route cleanly. This OEM-style coolant hose uses EPDM construction and a factory-molded shape to support coolant, water, and air transfer in HVAC and cooling system service.

Compatible With select Saturn Vue, Cadillac Eldorado, Volkswagen Golf, Volkswagen Jetta, and other listed applications, this molded heater hose follows the original routing for a direct replacement. The Gates Molded Heater Hose line focuses on OE-style fitment for modern compact engine compartments.

Detailed Description

This molded coolant hose is shaped to match the routing demands of smaller, tighter-fitting engine compartments. It is used in heater and coolant circuits where a formed hose is needed to connect components without kinking or forcing the line out of position. The Gates 19734 hose is listed for heater-to-pipe, heater-to-tee, heater-to-valve, coolant rail-to-heater, and tee-to-reservoir locations across multiple vehicle platforms.

Fitment includes 2004-2007 Saturn Vue, tee to reservoir; 2000-2002 Cadillac Eldorado, heater to pipe-1; 1999-2001 Volkswagen Golf, coolant rail to heater; and 1999-2001 Volkswagen Jetta, coolant rail to heater. It also appears in Cadillac DeVille, Eldorado, Seville, Fleetwood, and Commercial Chassis applications. This part cross-references Dayco 86109 and Continental 64326 for the same application.

What It Helps Solve

• Coolant hose routing problems in tight engine compartments
• Kinking or collapse from using a straight hose in a formed path
• Heater circuit leaks caused by aged or cracked rubber hose
• Improper fit at molded connection points
• Service replacement for worn heater-to-tee, heater-to-valve, or coolant rail connections

Installation Notes and Tips

• Verify end inside diameter, centerline length, and molded shape before installation.
• Match the hose to the exact routing position listed for your vehicle.
• Inspect adjoining pipes, tees, valves, and clamps for wear before reassembly.
• Confirm the hose is seated without twist so the molded shape follows the original path.

Quality Assurance

Gates manufactures this hose as an OEM-style molded replacement for cooling and HVAC service. The EPDM material and factory-formed design support consistent routing in the applications listed above, including Saturn Vue, Cadillac Eldorado, and Volkswagen Golf and Jetta fitments.
