DIY Air Conditioning
Now it's time to remove the compressor. This is very straight forward.
First you need to remove the belt by loosening the two 13mm bolts holding the a/c idler pulley onto the block. Then loosen the adjustment nut
until the belt slips off.
Time to remove the A/C compressor! If you can reach the lower 12mm bolt under the alternator, you can just remove the entire A/C bracket with the compressor attached.
The bottom 12mm bolt does not need to be removed. Just loosen it. The bracket has a slot rather than a hole for the lower bolt.
The final piece to remove is the expansion valve. You need to remove the 4 torx screws holding the evaporator cover on.
Slide it off and you will see the expansion valve. There are 2 copper lines that need to freed up and then the valve can be unscrewed.
Now it's definitly beer break time
