Gates 18080 HVAC Heater Hose

Gates Molded Heater Hose 18080

The Gates 18080 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a formed routing path matters. Made from EPDM, it serves coolant, water, and air applications and is also approved for marine use.

For vehicles that need a small I.D. molded hose, this Gates Molded Heater Hose line focuses on factory-style fit and routing. It is a practical choice for heater circuit service on applications such as Chevrolet Malibu, Pontiac G6, and Saturn Aura, as well as older Ford and Volkswagen models listed below.

Product Details

Gates 18080 is a molded heater hose with a 6-inch centerline length, 16 mm (0.62 in.) end 1 inside diameter, and 19 mm (0.75 in.) end 2 inside diameter. The molded EPDM construction helps maintain the formed shape needed for heater-to-tee, valve-to-pipe, pipe-to-water-pump, and similar routing points found across HVAC and cooling systems. This part cross-references Continental 63030 for the same application.

Fits 2007-2010 Chevrolet Malibu, heater to tee. Fits 2007-2010 Pontiac G6, heater to tee. Fits 2007-2008 Saturn Aura, heater to tee. It also covers select Volkswagen Cabrio, Cabriolet, Jetta, Rabbit Convertible, and Ford Taurus, Aerostar, and LTD applications listed in the fitment data.

What It Helps Fix

• Coolant leaks from a cracked or softened heater hose
• Restricted heater flow caused by hose collapse or internal wear
• Poor routing in tight engine compartments
• Heat-related hose deformation near the heater circuit
• Service issues on molded hose runs in HVAC and cooling systems

Installation Notes

Verify the hose path, end diameters, and centerline length before installation. Match the molded shape to the original routing so the hose clears nearby components and maintains proper flow. Confirm the vehicle’s heater circuit connection points, especially on Chevrolet Malibu, Pontiac G6, and Saturn Aura applications, before final assembly.

Quality Assurance

Gates supplies OEM-style molded hoses engineered for formed routing in modern and older engine bays. The 18080 follows the Gates Molded Heater Hose product line approach for accurate shape, material selection, and application-specific fitment.
