Answer
dump out the oil from the new compressor and install new oil in the same amount that you drained from the old compressor into the new compressor OR you can use the vacuum method, It is just a matter of preference.

You can get the cheap plastic tools to seperate the evap fittings at any auto parts store.

Don't forget to remove the orifice tube (if applicable before you flush your lines and install a new one when your ready to put it back together.

On some occassions you do not get all the debris out of the system and after a week or two the air starts to get warm. Just dump all the freon and inspect the orifice tube and you will find it full of debris. Either clean it with air or replace it.
