  1. Install the A/C Pressure Test Adapter on the rear head 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 such as the R-134a A/C Service Center to the corresponding fittings on the A/C Pressure Test Adapter.
  3. Attach the center hose of the manifold gauge set to a refrigerant container standing in an upright position.
  4. Hand-rotate the compressor shaft 10 complete revolutions to distribute the oil inside the A/C compressor.
  5. 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.
  6. Using the Automatic Calibration Halogen Leak Detector, check the entire A/C compressor for leaks.
  7. If an external leak is found, install a new A/C compressor. For additional information, refer to AIR CONDITIONING .
  8. When the leak test is complete, recover the refrigerant from the compressor.
