ok we definately have an expansion valve not an orfice tube. The Expansion valve is found in the evaporator.
God I love my toyota FSM!!
So what do I flush with? Coolant?
Also how much compressor oil should I put in the used compressor?

good link and good read.
question - when they flush the system fully, and its all completed, the system cant be exposed to atmosphere right? Or does it matter since the next step is evacuation?
Sorry for all the questions...

Ok im not thinking clearly here...uggg You guys with experience is this a wise course of action? Money very limited right now...
The last time my truck was in, my evap and compressor and clutch were shot. As a good rule of thumb, per my AC dude and you guys, accumulator and expansion valve should be replaced with new.
Im buying a guy's fully operational AC system from here to swap out the evap and compressor.
After installing those (how do I add the oil?) Im taking it to the AC guy and have him flush, evap, convert, and charge with r134.
Parts cost will be about 90 bux and then whatever the AC guy charges me....
I realize that the used parts (compressor and evap) are goign to be the weak links but I just cant afford new...or even remanufactured units. Is this a wise course of action or should I just grin and bear it for a few months saving up $$

But how do you know if the oil is out or not? Like on mine, I did a compressor swap with my engine swap and had the R-12 recovered by the dealer in my original system before I started removing the engine. Do you think they recovered most of the oil too?

Evec'ing the system and flushing it is not the same thing.
Flushing is done after the evac., assuming that the system was closed to begin with, thus requiring the evac.

It wasn't flushed, just the evac. So is most of the oil is still in there? That one link posted said Toyota doesn't recommend flushing. I kept my system as clean as possible by plugging up all the opennings with rubber stoppers and wrapping with tape while the hoses were disconnected.

Did you replace the dryer ?
That really should be replaced if the system is opened for any time as it contains a dessicant to dry the freon and exposing it to air, especially if you're live where it's the least bit humid will generally overload the dessicant in the dryer.

Some percentage of the oil is/was still in there. Don't know if there was oil in the used compressor that you swapped in or not.

I found this write-up today: http://www.asashop.org/autoinc/march2003/mech.cfm
Do our compressors hold oil?
