Hi, Actually every year they add dye and they can never find any leaks later. It doesn't leave any traces apparently. I plan on rebuilding the entire A/C in a year or two, but I just need to get through the summer. That's why I was wondering where I am sitting, short of replacing everything due to age.

Once the leaks are repaired, then you can worry about pressures and capacities. Fargo, ND 1982 DeLorean DMC12 VIN 11596 ************************************** See what's free at http://www.aol.com.
