F Hose – GM (85643577)

The f hose here is the GM part, numbered 85643577. It is catalogued under Hoses & Lines > Hoses.

• Torque figures belong to the fastener and the joint rather than to the part, so the factory procedure is the reference rather than a general rule.
• A part that fails early usually points at an installation fault or a worn component nearby rather than at the part itself.
• Where a diagram shows several similar items on one assembly, the difference between them is normally length, shoulder or handedness.

The photographs on a listing show the actual stock item, so compare the mounting points and the connector or fitting rather than the overall shape. 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.

Worth checking against the original before fitting. If you cannot read the number, we can match it from the VIN. Leaves our US warehouse in one to two business days, and shipping is free over $59.
