External Leak Test

1.  Install the A/C pressure test adapter on the rear head of the A/C compressor using the existing manifold bolt.

2.  Connect the high and low pressure lines of 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 on the refrigerant container to allow the refrigerant vapor to flow into the A/C compressor.

6.  Using the refrigerant leak detector check for leak at the compressor shaft seal and the compressor center seal.

7.  If shaft seal leak is found, install a new shaft seal.

8.  When the leak test is complete, recover the refrigerant. (See DISCHARGING AND RECOVERY.)
