I spoke with a LEXUS Tech and he said it would be fine you use a 1995 SC400 (r13 freon)ac compressor in my 1992 SC400. He wasnt sure if it will bolt right up but if it does then it will work.

Does anyone know if a 1995 SC400 ac compressor will fit on a 1992 SC400??

Does anyone know of a good link that could walk me through a proper AC conversion on a SC400??

Im looking to get my ac working for as cheap as possible!! Thanks

It's not the compressor that cuts down on efficiency so much as it is the condenser...

But, if you are intent on converting, you should replace the accumulator, the receiver/drier, flush all the lines in the system, flush the condenser and evaporator, install compressor, oil, and charge system...

I would not recommend doing this yourself unless you have the correct tools and gauges...

edit: and for the record, just because they work for Lexus doesn't mean they know all the tech specs and cross reference info... I've found many dealerships give me wrong info, and they supposedly have the "correct info"

I have a friend that works at toyota and I usually have him do things beyond my means.

If I bring him my 1992 SC400 car and hand him the 1995 compressor I bought, how much am I looking at spending on getting my ac working again.??? Keep in mind he will do the labor for pretty cheap. How much just in parts? Im looking for buying the bare minimum parts I absolutly need. Any thing I can leave alone I will. Thanks

couple hundred... I don't have access to parts prices right this second, but receiver drier and accumulator should be less than $150 for the pair, you'll need flush chemicals ($25 or so), then oil $10, and r134...

that will get it "working"

Cheap R12 to R134 "conversion kits" are R134 high and low side fittings that you screw on with some lock-tite and a few "converted to R134" stickers. As for how long a converted system will work is anyones guess. Why don't compressors have a drain plug? Seems strange they dont have one for servicing the oil when they are received and installed. Most come prefilled with some but they tell you to drain and add the 'correct' amount per your service manual.
