To remove the compressor, you need to unscrew all the mounting bolts except for one, which is too lengthy to be removed. This means that you have to remove the complete compressor to block mounting adapter.
There is a bolt located at the back of the mount, which is rather evident. Additionally, there are a pair of bolts that are positioned inside recesses in the mount itself, connecting it to the block.
When reassembling, ensure that you move the mount, with the single long bolt loosely attached to the compressor, as you position the mount back onto the block.
