Gates 18969 HVAC Heater Hose - Heater To Intake, Heater To Valve or Pipe-2 To Heater

Gates 18969 Molded Heater Hose Overview

The Gates 18969 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. Its factory-molded shape supports clean routing for coolant, water, and air applications, and it is approved for marine use.

Made from EPDM, this Gates Molded Heater Hose is sized with a 0.62 in. inside diameter at both ends and a 20.8 in. centerline length. It is a direct-fit style hose for vehicles such as the Chrysler Pacifica, Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Sierra 2500 HD, GMC Sierra 3500, and Nissan 280ZX in the listed heater hose positions.

Detailed Description

Gates 18969 is part of the Molded Heater Hose line, a product line focused on formed coolant hose routing for modern and older vehicles with limited clearance. The molded shape helps match the original hose path, which is important when replacing a heater hose that must bend around intake components, pipes, or valve connections without kinking. This makes it a practical choice for Chrysler Pacifica heater to intake service, Chevrolet Silverado 2500 HD and Silverado 3500 pipe-2-to-heater applications, GMC Sierra 2500 HD and Sierra 3500 heater hose routing, and Nissan 280ZX heater to valve replacement.

This Gates 18969 hose cross-references 10969 and 18083L for the same application.

What This Hose Helps Address

• Coolant leaks from a cracked or aged heater hose
• Kinking caused by a hose that no longer holds its formed shape
• Poor routing in tight engine compartments
• Heat-related hose deterioration in heater circuit service
• Replacement needs for molded coolant hose routing on listed vehicles

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. Match the molded shape to the original routing so the hose clears nearby intake, pipe, and valve components. Inspect adjoining clamps, fittings, and connection points for wear or corrosion before installing the new hose.
