Availability: 6 in stock
The fitting here is the GM part, numbered 19187913.
It is catalogued under Hoses & Lines > Clamps & Fittings.
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. Corrosion at a mounting face is worth cleaning back before fitting anything new, because a part that sits on scale will work loose.
In stock and sent from the US in one to two business days, free delivery over $59. Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone.
