Where is low pressure freon port on 2005 Subaru legacy?

On a 2005 Subaru Legacy, the low pressure refrigerant port for the air conditioning system is typically located on the larger diameter aluminum line that runs from the evaporator to the compressor. It can usually be found near the front of the engine bay, close to the driver's side. Look for a service port with a blue or black cap, which is designated for low pressure readings. Always ensure the engine is off before attempting to locate or service the AC system.
