It's not really that difficult. Here is a step by step.
Remove the tensioner.
If you can, put the bottom part, the part that does not rotate that the bracket attaches to in a vice.
Pull it over a little and use a screw driver and pry the black plate on the front off.
Really, all you need to do is twist the tensioner the other way and put the black plate back because all it does is hold the tensioner togeather and stop the twist. However, the pulley won't be in the right place.
Pull the tensioner apart.
Drill a new hole in the base (bracket end) so the end of the spring can seat in a new hole so when you put it togeather it will be in the right place.
I probally just confused you, it's really simple but hard to explain.
I hope I shed some light on what your are wondering.
The proper way to delete A/C is with a delete kit.
