Where do you put refrigerants in a 2002 Chevrolet Malibu?

There isn't a single place to "put" refrigerant in a 2002 Chevrolet Malibu's AC system. Refrigerant is added through a low-pressure port located on the AC system's components. This is usually a service port with a Schrader valve (similar to a tire valve) and is typically accessed from under the hood.

You should NOT attempt to add refrigerant yourself. Adding refrigerant requires specialized equipment to measure the pressure and ensure proper charging. Improperly adding refrigerant can damage the AC compressor and other components, leading to expensive repairs.

To recharge the AC system, you should take your 2002 Chevrolet Malibu to a qualified mechanic or auto AC specialist. They have the necessary tools, knowledge, and safety equipment to diagnose the problem and properly recharge the system. They will be able to identify the low-pressure port and add the correct type and amount of refrigerant. Simply locating the port yourself won't be sufficient for safe and proper AC repair.
