Factory A/C Parts List?

sarg · Post by **sarg** » Fri Apr 22, 2005 9:44 am

My local wrecking yard has an 85' with factory A/C I want to salvage and install in my 83' SR5. I'm not sure of all the parts associated with A/C? I'm thinking I need the compressor and bracket, evaporator, On/Off switch and probably a relay for the carberator idle. Can anyone tell me if I'm missing something? The wrecker cut the A/C hoses, can anyone source replacement hoses?

Also, I saw on an earlier post regarding A/C that the cars are factory wired for A/C. Are all years wired or just some?

There is a black control box for the AC behind the glove box.

You're taking on a big job.....?

I did an a/c install with junkyard parts, yes it's a big job but follow the wiring diagrams and it's pretty straight-forward. Use all new seals while you're at it and check for leaks with air pressure before you waste any refrigerant. You need:

Compressor
Compressor bracket
Alternator bracket from A/C equipped car
Condenser
Condenser fan
Condenser mounting bolts and rubber bushings, some of these are unique
Condenser fan relay from fuse box
Condenser fan fuse from fuse box
Evaporator
Rubber grommet in firewall for evaporator lines
Receiver/Drier
A/C amplifier (Takza mentioned)
A/C button for heater panel, this is the best part!
A/C idle-up VSV vacuum switching valve
A/C idle-up actuator mounted next to carb
Connectors for all of those pieces, or full harness
Aluminum lines

The A/C harness is somewhat independent of the main harness and with a bit more initial work it can be seperated as one piece and then installed in your car. I reccommend this rather than snipping the connectors and wiring them together. This takes you longer and if you're like me, you'll do shoddy work hurrying to get the job done, and end up with a rats nest of wires routed in the worst places.

Be careful undoing the nuts on the aluminum lines especially those going to the evaporator through the firewall. Too much torque and you'll screw the line. Use two wrenches applying force in a precise way, with as small an angle between the handles as possible. When they start to move, check to make sure the nut is rotating on the line, not twisting it. If it's really stubborn, use a torch on the nut but don't burn the rubber grommet.

Keep everything clean and dry while being transferred and put fresh compressor oil in the compressor first. To save yourself some headache you might want to replace the receiver/dryer and or the expansion valve with new ones from the start, some say these need replacement whenever the system is drained (mine worked fine with the original parts).

My system worked for a summer, sometimes ice cold but other times it was weak. After the winter it didn't work, and I found out it had leaked the refrigerant. I never did find the leak.

I have an installation guide for the A/C system on a CD. If you need a copy of this e-mail your address to me and I will send you one. Or better yet.. if someone could educate me on the correct way of doing it I can post it in the proper place on the forum.

A couple of suggestions...get an O-ring replacement kit from Toyota when you reassemble the components in your car....and think about using R-134a instead of R-12.

R12 is hard to get these days and unfortunately R134a performs worse and is hard on the compressor. I like using R12 substitute which is available without having a license and relatively cheap.

Thanks for the help guys.

Now I just have to convince the wrecker that I need to do the removal from the donor car not one of their guys. They get a little heavy handed during their removals.

By the way, I just got the factory repair manual for the 83' Tercel from Toyota, so if anyone needs reference, let me know.

Chris, I'll send you my address, my repair manual is vague on installation.

If the junkyard removes it you will need all new lines and somehow you'll have to find all the wire connectors they snipped off and the small parts they didn't know about. The only way is to do it yourself.
