If the advantages of the new compressor attract you so much, you can change it. But I don't recommend it. First of all, remove the exhaust manifold from the engine. After that, loosen the generator belt and release the compressor pulley. Next, an external inspection of the compressor is performed, and the freon circulation tubes are removed. After that, pull out the plug with the wires from the compressor connector and unscrew the nuts of its fastening. Remove the old compressor, and install a new one in its place. But in general, I don't advise you to do it yourself. It's better to find affordable and reliable aircon service.
