Gates 19606 HVAC Heater Hose

Gates 19606 Molded Heater Hose Overview

The Gates 19606 is a factory-molded heater hose built for tight engine bays where a straight hose will not route correctly. Made from EPDM and formed to OEM-style dimensions, it serves coolant, water, and air transfer needs and is approved for marine applications.

For Ford Mustang, Ford Thunderbird, Mercury Cougar, and Lincoln Continental applications, this molded hose helps restore proper routing in heater and HVAC circuits. The Gates Molded Heater Hose line is engineered for vehicles with compact underhood packaging and original-style hose paths.

Key Features

• OEM-style molded hose for precise routing in smaller engine compartments
• EPDM construction for heater, coolant, water, and air service
• 19 mm (0.75 in) inside diameter at both ends
• 11.6 in (295 mm) centerline length
• Compatible with marine applications
• Part number: 19606

Detailed Description

Gates 19606 is a molded HVAC heater hose designed to match factory hose geometry and maintain proper flow path in crowded engine bays. Its EPDM material supports coolant and heater service, while the molded shape helps it follow the original routing used on select Ford, Mercury, Lincoln, Buick, Oldsmobile, and Pontiac vehicles. This part number 19606 is a direct-fit style solution for applications such as 1987-1993 Ford Mustang, 1984-1989 Lincoln Continental, and 1987-1988 Mercury Cougar heater hose routing.

This part cross-references Monroe Shocks & Struts (e.g., 71499) for the same application.

What It Helps Address

• Leaking or cracked heater hose sections
• Improper hose routing in tight engine compartments
• Restricted coolant flow through a damaged molded hose
• HVAC heater circuit service on select Ford, Mercury, and Lincoln models
• Replacement of aged OEM-style coolant hose bends

Installation Notes and Tips

• Verify end diameters and centerline length before installation.
• Match the hose routing to the vehicle’s original heater hose path.
• Check nearby clamps, pipes, and fittings for wear before reassembly.
• Some listed applications note cut-to-fit use or protective sleeve requirements; confirm the exact vehicle configuration before installation.
• Use the vehicle’s service information to confirm heater-to-pipe, heater-to-water-pump, or heater-to-intake-manifold routing.

Quality Assurance

Gates manufactures this molded heater hose as an OEM-style replacement for select factory applications. The EPDM construction and molded profile support consistent fitment for vehicles requiring a 19 mm heater hose with an 11.6 in centerline length.
