Hmm... what do they say about arguing with people on the internet...

I think we are now down to only one person being on the wrong side of the condenser.... and definitions.... LOL

From leathermang: "Did I miss where you listed the specifics of that ' liquid ' cleaning product ? "

91% isopropyl alcohol works well as a flushing liquid, will grab any moisture lurking about and is volatile enough to boil off at room temp and not leave residue. Don't forget to flush out the new hoses.

from Bill Grissom: "buy Oeticker "stepless ear clamps" on ebay"

McMaster-Carr sells the clamps & the install tool if you can't find them.

Good luck.

I expect that is a good one for cleaning.. Thanks...

I was referring to this one....''Thats where I found this liquid refrigerant cleaning method. But its pretty hard to find and a bit expensive for DIY but it does get it clean for reuse.'' Which I think turned out to be that professional flushing machine at a shop...

Sorry I called this an accumulator. I had no idea what it was, or what else to call it. That's why I wanted some input.

No problem.. in a certain physical sense it IS an accumulator... just NOT in the automotive Air Conditioning sense... that is why the group is here... to try to make sure the final advice to the one needing it is as good as we can hash out..

wow... thread sure exploded...

be glad it's not a gasser...

they have one on the suction side too... with a fuel line passing through it! to cool the fuel prior to the injection pump to prevent any bubbles from hitting it!

I've always been fascinated by that device. Was MB the one one to use it? I've never seen one on a CIS VW / Audi product.

most of these are legit AC accumulators.. but I suspect some of the mufflers have been included... I think some Chrysler products had the muffler on the oid York V units... way back...

I was talking about the fuel line cooler found on gas W126s.

Well, this did have a fuel line heater, but I deleted it.

Anybody doing this who is re-making hoses and worried about internal debris or future clogging of the compressor outlet muffler, could simply eliminate it. >99% of vehicles on the road don't have such a muffler. I doubt there is anything unique about the 1991 compressor, and it probably has many pistons for a smooth flow (like R4 or Sanden). Even most old 2-piston compressors didn't have mufflers (Chrysler's RV2, Ford's York). Less clutter in the engine bay and won't materially degrade your ownership experience. While doing that, perhaps toss the "aux water pump", headlamp wipers, CD changer, etc.

I think what you say is true...
I think the purpose of this one may be to make a drastic TURN in the ' lines' which they could not figure out how to do otherwise...
