You should purge the yellow supply hose from can to manifold every time you connect a can.
It doesn't take much and I didn't waste but a fraction of an ounce each time.

Our GS's take 19.4-22.9 ounces of 134a refrigerant.

as i mentioned, with the YJ 4 valve manifold there is zero 134a waste, its also an EPA issue to vent 134a. with a 4 valve manifold you close off all the valves, switch cans, open vac and ref valves, vac it down, close vac line, open can, open lo side and fill, etc. purging can still be done, but no need.

and no, i dont have a 26oz can, i have a 12 & 14.

(Also, not replacing the drier will void the warranty on your new compressor). Keep in mind that your compressor fails for a reason. Whether its due to lack of oil, worn out, or whatever, the metal components in the compressor shave off and accumulate in the lines/drier and other parts on your AC system. I know from experience that if you do not replace your drier that it definitely can screw up your new compressor. A friend of mine replaced his compressor twice without replacing the drier and each time the new compressor failed within 2 weeks. That is enough for me to take the advice I was given and spend an extra $150 and do it right.
I went to the dealer today and they informed me that my compressor is bad. I see that rockauto has the condenser with the drier or the drier bag by itself. Can anyone tell me if the condenser really needs to be replaced and I can't just put in a new drier? I'm waiting on an estimate report from lexus since I forgot my copy at the dealer. I know the drier was mentioned on the estimate but I don't think the condenser was mentioned.

It's a lot of work to repair the ac and do it correctly meaning yes, replace the drier, compressor, O rings, PAG oil, flush the lines and vacuum the moisture out. Don't skip any steps or you'll be repairing your ac in a few months. Just my .02

its not so bad if you get a decent manifold set and good vac. new compressors typically come loaded with PAG. putting in a new drier means adding some PAG to the condenser. not all terribly hard to do, but definitely need right tools for a full DIY.

i might suggest to DIY the parts but let a local AC place to vac and fill.

I did not ask them for a test report, I should have Unfortunately, I have already ordered the condenser and compressor from Rockauto.

I bought a new Denso compressor and condenser. Both should be loaded with PAG already right? I found a shop who wanted to charge $500 labor if I brought the parts. It wasn't the most organized shop but it's my only local option. The dealer wanted $2000

I would prefer to do as you said and put the parts in and just have someone vac and fill. I would need to flush the system myself though and I don't have an air compressor. Need to see if I can get a hold of one. I really prefer to do as much of it as I can because I don't like having others work on my car, especially with so many half a$$ shops in my area.

my condenser (Denso first-time-fit) did not come with oil in it. the lexus maint manual says to add PAG to condenser when replacing condenser. see attached PDF. $500 doesnt sound too bad for the labor needed to do the install and recharge. do they give a 12mo warranty? tell them to get a TIS daily pass, get all the maint data they need to do the job, and make sure they have torq wrenches. you even need to replace the o-rings on line fittings....

i would let them do it all so to minimize the lines and parts being exposed to moisture in the air.

I got the same condenser and the Denso compressor as well. They showed up today in fact. I don't know if they have access to TIS, but they accessed something on the computer to get labor. I have some TIS stuff on my computer. I may look for the other stuff and bring it with me as I believe I have the shop do it. Thanks.

I just got my condenser/drier and compressor changed today. I just went drive it and checked the center vent temp tonight. It's currently 78F, 91% humidity outside. I drove it around at about 35-40 mph and put the AC on 65F and max fan speed. I got 47F at the center vent. I then parked the car and at 65 and the lowest fan speed, I got 32.4F. That sound like proper temps to you guys?

i would expect the temp to be lower when the AC pump is running at higher rpm's. but the temps you listed sound good.
