Question about 1999 Mercury Grand Marquis
It uses 134. Remember to use the correct type of oil charge if the compressor is noisy. If you are doing it yourself and want to purge the system, you can get a vacuum pump on loan from Autozone or Oreillys. It is a big deposit but you get the money back when you return the machine.
