Product Details

Gates Molded Heater Hose 19279 is a formed HVAC heater hose designed around the dimensions and routing needs of modern engine compartments. The EPDM material helps it handle coolant service while also supporting water and air applications. This molded hose is a practical choice for vehicles that need a shaped replacement rather than a straight universal hose, including Chevrolet Express and GMC Savana applications with auxiliary heater plumbing, as well as Chrysler Sebring, Dodge Stratus, Mitsubishi Eclipse, Mitsubishi Galant, Cadillac DeVille, Oldsmobile Aurora, and Pontiac Bonneville fitments.

The Gates molded heater hose line focuses on factory-style fit and routing, which is important when replacing a hose that must clear nearby components and follow the original path. Part number 19279 is also cross-referenced with Continental 64259 for the same application.

Installation Notes

Verify hose routing, end diameter, and centerline length before installation. This molded hose is listed for specific heater and auxiliary heater pipe positions, including Valve To Auxiliary Heater Pipe-1, Heater Inlet, Heater Outlet, and related pipe-to-pipe routes. On applications marked cut to fit, trim only as needed to match the vehicle’s original routing and connection points. Inspect clamps, pipe ends, and nearby components for wear before final assembly.
