Where is low pressure ac refill on the 2001 Malibu with v6?

On the 2001 Chevrolet Malibu with a V6 engine, the low-pressure AC service port is located on the larger diameter aluminum line that runs from the compressor to the evaporator. It's typically found near the accumulator or the firewall, often on the passenger side of the engine bay. The port is usually capped with a plastic cover and has a smaller fitting to accommodate the low-pressure refrigerant hose. Always ensure the engine is off and the AC system is not under pressure before attempting to access the service port.
