Where do you put freon on 2015 Ford Fusion?

To add Freon (refrigerant) to a 2015 Ford Fusion, locate the low-pressure service port, which is typically found on the larger refrigerant line, usually near the front of the engine compartment. The port is usually capped with a plastic cover marked with an "L" for low pressure. Use a compatible refrigerant and a charging kit to connect to the port, following the instructions for proper filling. Always ensure the AC system is off during the process and check for leaks afterward.
