Gates 19997 Molded Heater Hose Overview

The Gates 19997 molded heater hose is a factory-shaped coolant hose built for tight engine bays and OE-style routing. It uses EPDM construction and a 6-inch centerline length with 15 mm inside diameter ends for a precise fit in select Audi TT, Audi TT Quattro, Volkswagen Golf, and Volkswagen Jetta applications.

Gates Molded Heater Hose is a product line focused on molded coolant hose routing for compact engine compartments. This hose is also approved for coolant, water, air, and marine applications, giving it broad service use where a formed small I.D. hose is required.

Key Features

• EPDM construction for coolant system service
• 15 mm inside diameter at both ends
• 6-inch centerline length for compact routing

Detailed Product Description

Built for smaller, tighter-fitting engine compartments, the Gates 19997 molded heater hose follows the shape needed for direct routing between the housing and pipe or connector and pipe locations listed in the fitment data. Its molded design helps match the original hose path on vehicles such as the 2000-2006 Audi TT, 2000-2006 Audi TT Quattro, 2002-2006 Volkswagen Golf, and 2002-2005 Volkswagen Jetta. If you are replacing a worn molded coolant hose on these platforms, Gates 19997 provides the correct formed profile for the application.

This hose cross-references Fel-Pro 11997 for the same application.

What This Hose Helps Address

• Coolant leaks from cracked or aged molded heater hoses
• Improper hose routing in tight engine compartments
• Heat-related hose deterioration in the cooling system
• Fitment issues when a straight hose will not follow the original path
• Service replacement needs on Audi TT, Audi TT Quattro, Volkswagen Golf, and Volkswagen Jetta models

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. Confirm the vehicle uses a housing-to-pipe or connector-to-pipe layout as listed in the fitment data, and inspect adjoining pipes, clamps, and sealing surfaces for wear before installing the new hose. The molded shape is important for proper routing, so compare the original hose orientation to the replacement part before final assembly.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement built to match the demands of compact cooling-system routing. The EPDM material and molded construction support dependable service in coolant, water, air, and marine applications.
