$333.82 price checked August 2026
If you require a replacement that matches original factory component standards for your vehicle, this is the right choice.
Where the 15-6100 Condenser Fits
The GM 15-6100 Air Conditioning Condenser is for owners of GM vehicles who need an original factory component that matches the 24.8-inch height and 41.8-inch width of the original equipment.
Restoring your vehicle’s climate control to factory standards requires a component that maintains the correct pressure balance and airflow. A high-quality condenser ensures the refrigerant transitions from high-pressure gas to liquid efficiently without restricting the system’s flow.
The GM 15-6100 Air Conditioning Condenser achieves this through its brazed and mechanically bonded aluminum construction. This design prevents the core leakage issues common in cheaper units by ensuring a secure tube-to-fin bond.
