A/C Compressor - External Leak Test

WARNING: This page is about a different car, the 2013 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the adapter from the A/C Flush Adapter Kit on the port of the A/C compressor, using the existing manifold retaining bolt.
  2. Connect the high and low pressure lines of a manifold gauge set or a refrigerant recovery/recycling station to the corresponding fittings on the adapter.
  3. Attach the center hose of a manifold gauge set to a refrigerant container standing in an upright position.
  4. Open the low pressure gauge valve, the high pressure gauge valve and the valve on the refrigerant container to allow the refrigerant vapor to flow into the A/C compressor.
  5. Using the Refrigerant Leak Detector, check for leaks at the compressor shaft.
  6. If an external leak is found, install a new A/C compressor.
  7. When the leak test is complete, recover the refrigerant from the compressor.
