93 SC400...

Replacing compressor with a used one I purchased from a fellow CL member and a new drier...do I need to add compressor oil, or should it be okay since it was already used?

Thanks.

just to be on the safe side add alittle. To much and you could cause problems. you never know how long that compressor has been sitting around. hope this helps man.

 

Thanks. Changed it around today...after reinstalling the (hopefully) good one, I realized the "manifold" looking things where the a/c hoses connect were a different layout, so I had to take the compressor back off and swap them around...in 94 degree, humid effin weather. I was not happy about the added time sweating my *** off with grease and dirt all over me!

Anyways, it's installed, but by then the a/c shop around the corner was closed, so I will take it in the a.m. to have them flush/vacuum/add oil/R134a. Hopefully it doesn't leak...

If anyone reading this thread needs info on how to convert a system from R12 to R134a, and the amounts of oil/refrigerant required, I found this PDF while searching Google...might save someone some time.

Also, thanks to Killa-HZ for this post...it helped A LOT. https://www.clublexus.com/forums/per...tallation.html

 

Fingers crossed this all works out.

 

thanks Scott...and thanks for the super fast shipping! seriously, sent Sat. afternoon from KS and in FL Monday before noon...that is awesome...

 

My ac job was a nightmare. Went through two compressors and three dryers and a condensor was leaking. After two months of back and forth to the shop and finding leaks it finally works now. It's ice cold. Finally bought a brand new compressor offline. Nearly five hundred bucks, but it was well worth it. Good luck with it and keep us I informed.

Scott is a great guy and a asset to the CL forum.

Don't get a big head Scott. :-)

 

Thanks...I hope my process is smoother! Wow. I don't have $650-700 lying around at the moment...

On a positive note...I put dye in the system last week, which led me to the 'leaking from the front seal on the compressor' diagnosis...I didn't see green anywhere else today, so I hope this does the trick...

 

That's exactly where my two remanufactured ones were both leaking. If this doesn't get it then I would just buy a new one NOT a reman one.

Let's keep our fingers crossed and hopefully you will have some ice cold A/C!

 

If not, I might buy some of this for now and see if it works...I know stop leaks are not that good, but this one received some pretty good reviews from A/C techs, and it's one of the few that seals compressors...has anyone heard of/used this product?

oh man AC issues are like my worst nightmare lol cause everything is so costly and it's like keeping your fingers crossed everytime you do something..


hope it works, i know we need our AC down in the South

 

Well, they vacuumed, passed the leak test, added 3oz oil and 1.75 lbs r134a and she's cold! Hopefully at least through summer!

 

good job

 

Thx =) I do notice a little green around the edge of the manifold looking thing I swapped over - I wonder if that will seal fully after some amount of operation, or should I be concerned?

It's very little (so far) - will keep an eye on it...

 

Of course no green is best...

fingers crossed!

 

Just a quick update...two days on from charging, and no leaks, even where the tiny bit of green was before is gone. I think it could stand a tad more R134a (they put in 1.75lbs, specs were 900g or ~1.984lbs) but I'm not sure if that small amount makes a difference? It's cold, but not COLD...ya know?! Big improvement, though!
