Fiero Air Conditioning Parts List (Page 4/4) RWDPLZ JUL 05, 06:10 PM quote Originally posted by cam-a-lot: Hello Great article- needs to stay out of archives. Trying to rememnber the correct WEIGHT of R 134A to charge my system on a V6 Fiero (has 3800 compressor) please advise? Ogre's link is broken 80-90% of the R-12's original 2.5lb capacity, which would be about 2.25lbs, or about 3 of the 12oz cans. cam-a-lot JUL 05, 09:46 PM Thanks If using a proper AC machine at a garage, do I still need to get them to manually add Ester oil? When they vacuum out the system, does the oil come out too?

Total oil capacity for the Fiero is 8oz, no matter what type. Many recovery machines are capable of flushing the old oil, but it's not as simple as just connecting the hoses to the low and high side ports. cam-a-lot JUL 07, 08:22 AM Thanks It is not a new conersion, car is already on R134A. Just seems to have a small leak that I cannot find. so I have to re-fill it each summer I did add ester oil when compressor and accumulator were changed a couple of years ago. Should still be in the system I would think I have new orifice ready to go, just wondering if I should be worried about ester oil richard in nc JUL 08, 06:11 PM quote Originally posted by cam-a-lot: Hello Great article- needs to stay out of archives.
