1996 2.3L

My refrigerant all leaked out and when I refilled it I noticed the high pressure side valve leaking. I found a replacement kit at autozone but I can't figure out how to get the original one out. Anyone know?

The replacement has a tool with it to put the new one in, but the original has nowhere to put the tool. Any ideas?

 

its called a schrader valve thats leaking...it is almost exactly the same as a tire valve stem...and it comes out the same way as a valve stem
