Where is the low pressure port for a 2003 Chevy Malibu v-6 air conditioner?

The low-pressure port on a 2003 Chevy Malibu V6 AC system is typically located on the accumulator/receiver-dryer. This is usually a cylindrical component near the condenser (the larger, usually black, finned unit in front of the radiator). The low-pressure port is usually smaller than the high-pressure port and is often capped with a blue cap.

However, you should not rely solely on this general information. The exact location can vary slightly depending on specific trim level and other factors. Always consult a repair manual specific to your 2003 Chevy Malibu V6. These manuals will have diagrams showing the exact location of all AC ports. Improperly identifying these ports can lead to damage to your AC system.

If you're unsure, it's best to have a qualified mechanic locate the ports for you. Working with refrigerant requires special training and equipment to avoid injury and environmental damage.
