I'm measuring the temps in the vents up front. I was hoping to hit 40* like I have in my 1st gen Neon right now. When my Lancer had AC in it, that was ice cold and awesome. I hope to have that on the...

I'm measuring the temps in the vents up front. I was hoping to hit 40* like I have in my 1st gen Neon right now. When my Lancer had AC in it, that was ice cold and awesome. I hope to have that on the...
I replaced the valve this morning and it works very well. The temps in the van were at about 50*, so that was a big difference. I'll continue to lower the pressure a little and see if that helps...
Granted, a person with experience would have had this licked in no time. I'm not sure how familiar the average shop around here would be with the old system in this thing though. I am certain it...
Well, my AC know how continues to grow while the actual AC is still luke warm. I tested the low pressure switch, and the connector to it. Those were both good. I tested the electronic clutch cutout...
Wow! thanks a ton for all of that info.
Well, I thought I didn't get something sealed up the last time I filled the van with refrigerant. However, the pressure was approximately 85PSI at 80* so I don't think that's it. The compressor won't...
I thought I waited a while with this last go, but I certainly didn't wait 5min. Once I get the bypass valve in I think I'll know if I need to give it another go. I will say that I drove the van to...
Here is another handy chart, and some neat math for those who think they might want to give this a try also.

OK. I'm feeling a little better about my pressures after checking this chart. I've clearly been looking at R12 weights and pressures way too much. Seems like my pressures are a little on the low side...
Alright. I changed out the condenser today and pulled a vacuum. It held, so I put two 20oz cans in there when it calls for 29oz of R12. I figured with what I purged off, I'm close to the roughly .6...
No kidding. I can't believe what people pay for the R134 stuff in the parts store. It's crazy.
You probably did and I missed it. I'm certainly learning a ton by doing this and I'm glad that I'm doing the air duster. This has been a very cheap way to make mistakes.
ETA: After taking a couple ounces of oil out of the system it did charge up much better this time. I never really saw the temps I was expecting and the min temp ended up being about 50*. However, if...
Another question if people are still following along...
What are you guys using for your conversion factor going from R12 to R152a? I have seen varying numbers ranging from .85 to .57. That makes...
If anyone has a link to the Chrysler A590 C171 AC compressor suction/discharge gaskets in perhaps a 10 pack for cheap, please let me know. I found a kit with all of them, but I predict that I'll need...
Well, the noise is officially eliminated with a pulley swap. My pressures are still very high for how much refrigerant was put in. I'm going to flush out the condenser and go from there.
I found this flow chart tonight. Looks like I most likely added too much oil to the system. I can't think of anything else which would cause the high pressure on both sides. The system was dead empty...
Thanks. This noise started as soon as I installed the AC and goes away when I remove the belt. I'm thinking It must be the pulley for the AC. Thanks for the link. I'll be looking into that for sure.
I agree. My Neon was pumping out 40F air and I had around 30PSI on the low side with 180ish on the high side. I'm pretty confused by this whole deal right now. I do think I need to change the pulley...
The video will be live here in a bit.

ETA: Since this noise is being made while the clutch is disengaged, and the pulley didn't make the noise when I spun it by...
Well, for every bit of success with the Neon, the Minivan seems to be as much of a disaster.
I'll have a video up ASAP of what the compressor sounded like. I thought it may have been the bearing...
Well, I used my new JE industries vacuum pump, gauge set, and can adapter today to successfully get my 95 Neon up and running with AC. I didn't have a thermometer, but I put in a little over 2 cans...
If I'm not mistaken, it's widely used in Canada and they don't have any problems with it.
That looks like it will certainly give some efficiency gains. Nice work.
Let us know how it works out. I'll probably remain certificationless.
