Hose – GM (19174413)

Factory part number 19174413: a hose supplied by GM. It is catalogued under Hoses & Lines > Hoses.

• Crimped hose assemblies cannot be repaired at home: the collar is machine-formed, and a clamp over a failed crimp will not hold system pressure.
• Coolant and refrigerant hoses see different pressures and different fluids, so the material is not interchangeable between the two systems.
• When a hose is replaced because of a leak, the mating fitting usually needs cleaning back to bare metal before the new assembly goes on.

Genuine parts are made to the drawing the vehicle was built from, so dimensions and materials match the part being removed rather than being close to it. Fitment lists are a guide rather than a guarantee, because the same model year can carry different parts depending on the production break and the option code.

The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. Leaves our US warehouse in one to two business days, and shipping is free over $59.
