How do you disconnect the hose from an ac condenser that connects to ac compressor? I have removed the freon (safely) and removed the clamp but the hose doesn’t come off. Do you need a special tool to disconnect this?

You might need one. Your Haynes manual should show you a picture. If you don’t have a Haynes manual, you might want to get one.

Do you have a vacuum pump to draw down the system?
