On a 2003 Lincoln, the freon recharge valve, also known as the service port, is typically located on the low-pressure side of the air conditioning system. This port is usually found on the larger diameter aluminum line that runs from the evaporator to the compressor. You can identify it by its larger size compared to the high-pressure port, which is smaller and located on the thinner line. Always ensure the engine is off and the AC system is not under pressure before attempting to access the recharge valve.

You add refrigerant at the low pressure port but you do not add Freon. You add R134/134a. If you are having to add refrigerant then you have a leak that needs to be repaired first.
