1993 mercury sable compressor replace on 3.8 eng

Compressors usually aren’t that difficult to remove. In your case it might come out easier from the bottom. Thing is you need to remove any old refrigerant BEFORE you disconnect it from the system. If there is still a charge in the system I’d recommend taking it somewhere to have the refrigerant removed before you start work. You might also hit them up when the work is done and you need to evacuate and recharge the system. The proper equipment makes all the difference with AC repairs. In addition if you’ve had a compressor failure I strongly recommend you flush the system before installing a new compressor especially if you find debris in the system. If you do find debris it’s a good idea to also replace the expansion valve as it may get clogged by this debris and cause other problems. Lastly, if you haven’t had working AC for a while you might also consider replacing the receiver dryer when you replace the compressor. BTW you can buy a spray can that will flush the system. Consult your parts professional for that one. In addition, you may void the warranty on your new compressor if you don’t flush the system when you install it.
