Before you put the S/C back on the car be sure and do the following, the fill port is on the back and it takes 5.1 oz of oil. Be sure the bypass valve (The gold circle in the picture) is fully closing, if not it's bleeding boost so use the adjustment stop to fix that. Check the couple for play, when turning the pulley the rotors should turn with NO play. If you got play the couple is bad, and you'll need to change it, or you'll be doing this job again soon.
