freon charge amount.
Just replaced leaking brings at the a/c compressor. Charge amount sticker has been missing since I have had the car. Anyone know what the freon charge amount is for a c5?

Again, its based upon the local temperatures and system capacity. A little too much, the over-pressure switch will insure it doesn't run. A little too little, it won't run either. If you know how to use the guages, cool and go for it otherwise you need a professional. I made this mistake already therefore I ended up at a professional shop. Its not like the old days with R-12, add till the bubbles in the sight-glass went away. R134 is a different monster and is installed differently.

When you OPEN up the AC System to atmosphere, there are several things that MUST be done to allow the system to work properly.
Replace the Receiver /Dryer (Bigsilver can behind the battery) and add the proper amount of the correct oil.
Vacuum the system out to remove all the air and moisture. Back fill it with 134a
Add the CORRECT ammount of 134a as per the chart in the service manual;

All you guys should follow bill's links. They are very good and informative. I just wanted to know what factory fill was so I could program the recycled machine. If you open up to atmosphere you should do you work right then and it takes only 20 minutes to vacuum the system down adequately. With r134 a little low is better than a bit overfull. I had .79 in my system and it was okay, but not freeze you out cold. I did the recovery, vacuum and recharge today, now it will freeze you of there.
