You are better off replacing the whole compressor. You can purchase a remanufactured compressor for $30 more and it comes with a 1 year warranty. Also replace the dryer/accumulator with this. It only has 4 bolts that hold the compressor on and it's a one for one swap.

First, remove the hoses from the dryer SLOWLY!!! This will allow the system to depressurize. Once the air stops hissing, remove the front and rear connectors from the dryer. Remove the 4 main bolts from the compressor and the one bolt holding the hose connections. Remove the serpentine belt and lift off the compressor.

CAUTION****** Drain the oil from the compressor and fill the new one with the same amount of new GM AC oil. Install the new dryer and the new compressor.

After installation, I suggest taking the vehicle to a service shop and have them vacuum the system and recharge it. You just saved yourself approximately $400 anyway, so having a professional perform these tasks is only a few dollars. This could save your new ac system in the long run.
