Installation Notes

Verify condenser dimensions and line connection points before installation. Replace any contaminated refrigerant oil, evacuate the system, and recharge to factory specifications after the repair. Because mounting hardware is not included, reuse or source the required fasteners as needed. For BMW 3 Series and X3 A/C condenser replacement, confirm that the surrounding cooling stack is clean and free of debris before reassembly.
