Buy a copy of the manufacturer's service manual. It will list all the steps along with drawings, precautions, special tools, and torque specs for fasteners. At the dealership I used to work at, the service advisers were happy to photocopy pages for you for free, with the blessings of the dealership owners, as long as you were willing to wait a day or two. They have to have someone find the older manuals that are in storage, then find the appropriate pages to copy, then do that after they were done talking with the long line of waiting customers and calculating estimates and calling people with those estimates. They often stayed late after hours to do the copying. We traded service information that way with the local Ford and Pontiac dealers too.

You'll need to disconnect the AC hoses if the car has air conditioning. Recovering the refrigerant should be done ay a shop with the right equipment. If you aren't familiar with the hazards of working with refrigerant, don't mess with it. Professionals use safety glasses, face shields, and gloves. '93 was the last year they still used R-12 refrigerant which is very expensive due to the extremely high EPA tax. Thank your government for that. You may want to convert the system to the less-expensive R-134.
