A/C temp

[5150neo]

I had the A/C recharged yesterday and the air temp never gets very cold. The previous owner had the system converted over to R-134. Can anyone tell me how many pounds of 134 the system should be filled with? And is this common, just life with an Esprit?

The capacity on my 95 S4s is 2.2 lbs. R134a.

With outside temps in the mid to upper 90's it blows 56-58 degrees F at the vents. Not cold enough......

I've had AC issues since new on my 2000 V8. However, after a couple shop visits for leaks and a bad compressor... I only had to fix 3 leaks and recharge the system :-(

Overall, not very impressed with the AC system... lots of expensive parts that perform poorly together. The manual does state that R134a systems require 2.2 pounds of refrigerant.... seems kinda low considering how much extra plumbing you have in the mid-engine layout.

Now that I've fixed the system ( both Hi and Lo valves slightly loose and the compressor manifold fitting) I can drive around (South Florida with 90+ degrees and very sunny) in a black car with black interior and glass roof with temperatures around 48 degrees from the center vents without air circulation. With air circulation on, it will go down to about 42 degrees. I've also noticed that if I put the blower fan on high (position 3) I get less cool air, so position 2 seems about best to keep adequate airflow and keep the small cabin reasonably cool.

One thing I don't quite know yet are what the average Hi and Lo pressures are suppose to be... nobody seems to know and as I had 3 leaks to find after the compressor was replaced (warranty work), it's difficult to know how much oil and refrigerant was lost. I did add another 2 ounces of oil however as the engine oil filter, oil pan and front frame section all had compressor oil about. Personally I think the system should blow colder from the vents.

Hope this helps.... can't really comment on how cold the R12 converted Esprit should be. I just don't know how many parts were swapped.

Thanks guys. The shop only put 1.2 Lb in the system, and when I checked the preasure it was below normal. Once again, I guess I have to do it myself to get it right. Easy fix.
Thanks again
