Replacing entire A/C system this month.
I recently purchased a new A/C system kit for my car complete with compressor, dryer, PAG oil, and orfice tube. The reason why I'm replacing the A/C is that the compressor front seal is blown, and when you add freon to it, it just sprays out from behind the compressor, and about 10 minutes later the A/C turns off because it has no freon in it. Is it really nesissary for me to have the system vacuumed out or can I just put the new parts on. There is NO freon at all in the system and it has been checked for leaks multiple times, and the only place it had a leak was comming out from behind the A/C compressor. It has never locked up or started knocking. The seal blew while the car was sitting in the drive way and when I went to run the A/C, the compressor didn't turn on so I took it in to the shop and had them hook it up onto a mechine and they said all I needed was a new compressor that it still cooled great so thats why I bought this system kit. Wish me luck.

Yes, it IS necessary for you to vacuum the system before and while charging it. Two reasons. An open A/C system (while you are changing it out) will absorb moisture. Plus, you need to remove as much outside air as is possible while charging, otherwise you will be attempting to compress some normal outside air along with all that expensive R134a. This results in a less-than-optimal result.
As I mentioned in a thread earlier today, I suggest bringing the completed install to a good local A/C place and having them charge the system. It'* usually not very expensive and you get the added feature of in-house leak testing right on the spot.

Our compressors are the Delphi H6, one of the most expensive (and least reliable IMO) compressors Delphi made. A new one will usually run you well in excess of $300. At least that has been my experience.

No, I'm almost positive you've got a V5 compresser (variable displacement 5 clynder) I know for sure that'* what my car has because I had it hooked up to A/C gauges once and for the life of me couldn't figure out why the compresser wasn't cycling. The low side just sat at 25 psi no matter what I did. Even if I turned the fan to low and heald the engine at 4000 rpm, no cycling. Later I found out I had a variable displacement compressor and it was opperating as it should have been. Oh well, live and learn.

Ours IS the V5. The autoaironline link above has them for a very reasonable price.

Re: A/C replacement
Well when I go to put all the parts on I'm gonna take it to a local shop and have them pull a vacuum and charge on it. It should run me about $70-85 depending on where I go.
R-134A is pretty cheap running about $7 a pound here in Texas. About a year ago it was only $4 a pound, but since R-12 systems have been dissapearing since 1994 the price has to go up I guess, along with everything else
