AC rebuild checklist
ok guys so ac is something i don't know yet.
i know this vehicle came factory w ac the the po removed it b4 i got it.
what all do i need to put it back together? the dash is plumbed for it, the heater works just fine.
i have so far:
compressor
evaporator core
drier
expansion valve
hoses in the engine bay that I think would plug into the condenser
some black cylinder with threaded piping on the top like a T, near the grill on the drivers side, maybe the old drier?
what do I lack to put a factory ac back together?
methinks:
a condenser? -should it be brand new or can they be salvage parts?
an evaporator core case? otherwise, what does my evaporator core go in? i bought the dumb thing and don't even know where it goes...
I think thats it, yeah? anything special about putting it back together? Since I have all the pieces in my hand right now, am I able to "convert" to R12 now? and how do I recharge this bad boy?? thanks guys

I paid over $1100 recently to have my aftermarket ac replaced. I'd definitly consider tackling it myself next time. Apparently R134 works better with a larger condensor. Also, befor you charge it with freon you'll need to evacuate the system to remove all traces of moisture.

Good to know. How's my parts list looking? Is that everything I would need?
Also, are condensers job specific or is a condenser a condenser? I have a old one that is in working order that I pulled from my 87 Jeep Comanche with the straight 6 4.0L standard AC fitting on the left hand side when facing from the front, like the Yotas. Any interchangeability?

As long as the hoses will all reach and the Jeep condenser will mount up, then I'd say use it.
That black cylinder up front is indeed the old drier. And my evaporator is inside of a plastic case, so you probably want that.
As for "convert to R12", I think you meant convert to R134. Once you get it all buttoned up with new o-rings, vacuum it down with a vacuum pump. I bought the 2.5CFM pump from HarborFreight for $69. I just got mine working and my A/C is pretty cold, and I live in Fort Lauderdale where it is still mid to high 80's even in October. Also, you will need the R134 fittings for the compressor hi and lo side. I bought the 90 degree low side fitting from ackits.com because I could not get the connector on there with a straight fitting.
Good luck.

So turns out that jeep condenser has both ports on the same side, not opposite like the oem yota's. Now heres a new direction.
If I relocated my drier/receiver to a good spot on the passenger side and rerouted some hoses/etc to connect everything up, things should still work right? I know it's an extra step but i already have this jeep condenser and don't really want to shell out for a new yota one that would require me to make new hard lines too.
Another route, any clue on approximate worth or functionality of a used AC condenser and lines from a salvage yard?
