However, there's no single definitive location. The exact position varies slightly depending on the specific model and engine configuration. You might find them low and near the bottom of the drier, or slightly higher. They're usually two ports, one low-side (usually larger) and one high-side (usually smaller), with a cap on each. They might be difficult to spot, and some are even tucked away behind other components.
To locate them with certainty:
1. Consult your owner's manual: It may have a diagram or description of the AC system components.
2. Use a repair manual specific to your 1997 Monte Carlo: A Haynes or Chilton manual will have detailed diagrams and explanations.
3. Search online for pictures: A Google image search for "1997 Chevy Monte Carlo AC recharge ports" might yield helpful images from others who have worked on the system.
Important Note: While recharging your AC system yourself might seem economical, it's crucial to understand that improper charging can damage your compressor and other components. If you're not comfortable identifying the ports and correctly using the recharge equipment, it's always best to have a qualified mechanic perform the service. Incorrect refrigerant levels can severely impact the AC system's efficiency and longevity.
