Gates 19126 HVAC Heater Hose - Heater To Tee or Heater To Thermostat

Gates Molded Heater Hose 19126 Overview

The Gates 19126 molded heater hose is an OEM-style coolant hose built for tight engine bays where a straight hose will not route correctly. Made from EPDM, it is shaped for factory-style fitment and is approved for coolant, water, air, and marine applications.

Compatible With 2004-2006 Jeep TJ and 2004-2006 Jeep Wrangler heater-to-thermostat routing, as well as 1994-1996 Cadillac Commercial Chassis and 1994-1996 Cadillac Fleetwood heater-to-tee routing. The Gates Molded Heater Hose line is made for applications that require a formed hose profile rather than a universal cut-to-fit hose.

Detailed Description

Gates 19126 is a molded heater hose designed to follow the original routing used in compact engine compartments. Its formed shape helps match the factory path between the heater circuit and thermostat or tee connection points, which is important on vehicles such as the Jeep TJ, Jeep Wrangler, Cadillac Commercial Chassis, and Cadillac Fleetwood. The EPDM hose material is selected for fluid-handling service in heating and cooling systems, and the molded profile supports a cleaner, more accurate replacement than a generic straight hose.

This part cross-references Carlson 19126 and BBB Industries 11126 for the same application.

What It Helps Address

• Cracked or leaking heater hose routing
• Collapsed hose sections in tight engine compartments
• Incorrect hose shape after prior repairs
• Coolant seepage at formed hose bends
• Restricted heater circuit flow caused by aged hose material

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. This molded hose is intended for heater-to-thermostat and heater-to-tee routing shown in the fitment data, so confirm the vehicle application and connection points on your Jeep TJ, Jeep Wrangler, Cadillac Commercial Chassis, or Cadillac Fleetwood before replacement. Inspect adjoining clamps, fittings, and mating surfaces for wear or corrosion during service.

Quality Assurance

Gates manufactures this molded heater hose as an OE-style replacement part for vehicles that require a formed coolant hose profile. Part number 19126 is built to match the listed dimensions and application-specific routing requirements.
