Gates 19226 HVAC Heater Hose

Gates Molded Heater Hose 19226

Gates 19226 is a molded HVAC heater hose built for tight engine bays where a straight hose will not follow the factory routing. This OE-style coolant hose uses EPDM construction and a factory-molded shape to support coolant, water, and air transfer in the heating and cooling system.

Key Features

• EPDM rubber construction for coolant and heater service
• Factory-molded profile for OEM-style routing in compact engine compartments
• End I.D. of 0.63 in. / 16 mm at both ends
• Centerline length of 20.6 in. / 523 mm
• Suitable for coolant, water, and air applications
• Approved for marine applications
• Gates 19226 molded heater hose for HVAC and radiator hose routing

Product Details

The Gates Molded Heater Hose line is built around factory-shaped hose routing for vehicles with smaller, tighter-fitting engine compartments. Part number 19226 follows the original-style bend pattern to help maintain proper hose alignment in heating and cooling circuits. It is a practical choice for service work on vehicles such as the Chevrolet Uplander, Pontiac Montana, and Buick Terraza where molded routing is required for the heater and auxiliary heater connections.

This hose is listed for multiple HVAC and coolant routing positions, including Tee-3 To Pipe-4, Tee-2 To Auxiliary Heater, Tee To Auxiliary Heater Pipe-2, Tee-2 To Heater, and Heater To Pipe-1. This part cross-references BBB Industries 11226 for the same application.

What It Helps Address

• Cracked or heat-aged heater hose sections
• Incorrect hose routing in tight engine compartments
• Coolant leaks at molded hose runs
• Service replacement for auxiliary heater and HVAC coolant lines
• Fitment issues on molded hose applications in Chevrolet Uplander, Pontiac Montana, and Buick Terraza models

Installation Notes

Verify the hose path, end inside diameter, and centerline length before installation. This molded hose is intended for applications that require the factory bend shape, so routing should match the original layout closely. Confirm the vehicle position listed for your application, especially on models with auxiliary heater plumbing or tee connections. Gates 19226 is also listed for 2000-2001 Acura Integra heater-to-pipe routing and several 2001-2009 GM minivan HVAC coolant applications.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement using EPDM material and factory-molded dimensions for consistent fit and routing. The hose is specified for coolant, water, air, and marine use, supporting a broad range of service applications.
