• Connect the low and high side hoses of the manifold gauge to their respective ports on the A/C system.
• Start the vehicle and turn on the A/C to the maximum setting.
• Measure the pressure readings on the gauge; if low, add refrigerant according to the manufacturer's specifications.
• Monitor the system for any signs of leaks during the recharge process.

4. Inspect and Replace A/C Compressor (if needed)
