Newbie w/ an AC question

[azmalibuwagon]

Hello, I'm new here, and look forward to learning a lot from you guys. I just picked up an 81 Malibu Wagon that has a 305H, 200r4, runs ok, but lots of things that need attended.

First up is to reinstall AC. The PO removed the AC compressor and lines, but it looks like everything else is still there.
I plan on visiting the local Pick A Part and grab a compressor and lines. I plan on converting to 134a.

Which compressor should I get? Any words of advice? All help is appreciated!

I did the 2/55 a/c option (2 windows down @ 55 mph) i would try to get stock parts, but you may want to pick up a refurbished compressor unless you know for sure the bone yard one is working

I coulb be wrong but Im pretty sure you can get a caprice compressor that was already set up for 134 but any system can be retrofitted with no orings and a flush.

My car uses an R-4 compressor, and I plan on using one for a 1994 S-10 with a 4.3 in it. These were native 134a cars, so the seals, etc. are probably right for this refrigerant. You can use a R-12 compressor, but if starting from scratch why not get one that was made for it? You will need to use a V belt clutch on it as the native clutch to the 94 S-10 is serpentine. This is all theory as of now (I don't have the cash to do it just yet), but I think it is pretty sound.

Thanks for the responses. I likethe idea of getting one that's already set up - maybe save a few bucks. It's good to know that if it looks like it will fit, then it probably will.

I've been doing the 2/55 a/c option for awhile, and too many days at 105+ here in Phoenix!

I would go for the rotary R-4 type compressor. Your best bet would be a new compressor, unless of course you can find a good used one that you know the condition of. Stay away from a refurbed unit. That's the consensus I've gotten from other people .
You may also need the proper brackets, unless there was an R-4 in there previously. You would also need a new receiver drier and orifice tube.

Agreed with the above. Minus the rebuilt compressor . Premature failure in the rebuilt units usually happens because of the previous compressor takeing a s$#@. And leaveing behind shaveings that people don't get flushed out! I work in a auto parts store and see it all the time. Is this the consumers fault ? No mostly due to back yard hacks that don't know what they are doing! Buy a reicever drier/accumulator and or orifice tube/expansion valve and flush the system on any car that you replace the compressor on......... Just my two cents. :|
