Car AC Lines Don't Come Apart 2008 Ford Mustang

 I've got a couple of scenarios I've run into when AC Quick disconnect lines not coming apart:

1. 2008 V6 Mustang:

I put a new accumulator on the AC system.  The new aftermarket part I put on was faulty and would not come back off with anything I tried.  I think the part was made just a little different than the OEM and would not allow to tool to expand the lock spring to release the pipe.  I wrestled with this thing for hours!  I ended up using a small sharp hook tool (and pair of scissors) to cut the inner spring. I had extras and they are cheap to place.  These pipes should be able to move and twist and turn.  These pipes did move so I knew they didn't have sealant on them.

2.  2007 Ford Focus:

 The accumulator on this car had be glued together with sealant.  These pipes would not move independent from one another. I ended up cutting the pipe in half on the accumulator that I wasn't going to use again.  If you do this, be careful not to cut into the ac line you are using again!  Then I soaked the end, I couldn't get off, in rubbing alcohol overnight. The next morning, the ac line was movable again. The rubbing alcohol had disintegrated the sealant use inside when the last person put it on.

I posted these here to help others having the same issues!
