The GM Genuine Parts 15-63816 AC Condenser fits your vehicle if your car was manufactured to the specific GM factory specifications that utilize this exact original equipment part number.
This air conditioning condenser, which acts as the first heat exchanger to cool the refrigerant gas entering your car’s cooling system, is a GM-recommended replacement part. Because it is an original factory component, it features brazed and mechanically bonded aluminum construction designed for exact fit, form, and function. We selected this specific component for our comparison because it serves as the baseline for material thickness and fin density against aftermarket alternatives. You must verify your production date because manufacturers often change parts mid-year, which can result in a “correct” part number being incompatible with early-production vehicles. Additionally, you should confirm if your vehicle requires specific refrigerant or oil types, as using incorrect fluids can cause internal chemical reactions or seal failures. Because this is a genuine part, it is designed to match the factory core thickness, but you should check your service manual to ensure your specific climate region does not require a different fin density for export versus domestic models.
