A/C Compressor - External Leak Test

1. Install the appropriate adapter from the A/C Flush Adapter Kit on the rear head of the A/C compressor, using the existing peanut fitting nuts.

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 the 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 the entire A/C compressor for leaks.

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.
