Gates 18769 HVAC Heater Hose

Gates Molded Heater Hose 18769

Gates 18769 is a molded heater hose built for tight engine bays where a factory-shaped coolant line is needed. This OE-style hose uses EPDM construction and a small 0.62 in. inside diameter at both ends to support coolant, water, and air routing in HVAC and engine cooling systems.

Compatible With applications such as Ford E-150 Econoline heater to pipe, Suzuki Grand Vitara heater inlet and heater outlet, and Dodge Nitro heater inlet and heater outlet, this molded hose follows the original routing needed for clean fitment in confined spaces. The Gates Molded Heater Hose line is made for vehicles that require a formed replacement rather than a straight universal hose.

Key Features

• Gates Molded Heater Hose, part number 18769
• EPDM construction for coolant, water, and air service
• Factory-molded shape for tighter engine compartments
• 0.62 in. inside diameter at both ends
• 14.3 in. centerline length for OE-style routing
• Approved for marine applications
• Direct replacement style for HVAC heater hose service

Detailed Description

This molded coolant hose is shaped to match the routing demands of modern and older vehicles with limited clearance around the engine and HVAC plumbing. The 14.3 in. centerline length and molded profile help maintain the original hose path, which is important for heater inlet, heater outlet, heater to pipe, and auxiliary heater connections. Gates 18769 is a practical replacement for vehicles including Ford E-150 Econoline, Mitsubishi Montero, and Suzuki Grand Vitara when the application calls for a formed heater hose with a 16 mm inside diameter.

This part cross-references Dayco 87646 and Continental 63122 for the same application.

What It Helps Solve

• Cracked or aged heater hose sections in the coolant circuit
• Improper hose routing in compact engine compartments
• Leaks at heater inlet or heater outlet connections
• Replacement needs for molded HVAC heater hose layouts
• Service on coolant, water, or air transfer lines

Installation Notes and Tips

• Verify end diameter, centerline length, and molded shape against the removed hose before installation.
• Confirm the vehicle position listed in the fitment data, such as heater inlet, heater outlet, heater to pipe, or heater to tee.
• Inspect adjoining pipes, clamps, and fittings for wear or corrosion before installing the new hose.
• Use the exact routing path to avoid kinks, twist, or contact with hot or moving components.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement for applications that require a formed coolant hose profile. The EPDM material and factory-molded construction support consistent fitment across the listed vehicle applications, including Ford, Dodge, Mitsubishi, Isuzu, Chevrolet, Oldsmobile, Pontiac, Mercury, and Suzuki models.
