The AC refill port on a Mustang with a 3.8-liter engine is typically located on the passenger side of the engine bay. It can usually be found near the firewall, on the larger diameter line that runs from the compressor to the condenser. Look for a service port with a plastic cap; it may be labeled with "Low" or "High" to indicate the correct pressure side. Always ensure the engine is off and the AC system is depressurized before attempting to refill.
