I'm trying to look ahead to spring and handle the air conditioning on my car and know of a working compressor I can probably buy pretty cheap.

Are you working on a Gen II car? If so, yes. If you're working on a Gen I car, you've got some fancy fabrication ahead of you unless you're working on a car that switched from R4/A6 to the Denso in '86.

I would upgrade to a parallel flow on the '84, works well with R12 and 152A. Klimakit.com has a really nice drop in PF kit, that is what is on my SD...ONLY because my original leaked. It will work on your SE also with different lines, easy. 85s had a better factory condenser, but finding one for the 85-87 Diesel W126s is basically impossible used. 90-91 was a different unit with dual aux fans.

I am not sure when MB upgraded the aux fan, engine driven fan, water pump pulley, etc on the the SD. I am thinking late '83. Mine being an 11/84 build (1985 model) has all the factory upgrades in that matter. The SD can also accept a V8 fan blade with clutch, they move a ton more air (that helps AC performance). If I could find a good, used clutch I would have one on my SD.

The R4 is also not a good compressor. I love my Sanden kit, guy on here does them and mine is from Klimakit. Best thing a 617 owner can do when they revamp their HVAC is dump the R4 in the trash.



If you mean your 380, I cannot see why a 420SEL A/C bracket would not bolt right up allowing the use of a Denso. I have not tried, so I cannot verify. I certainly would try. Plenty of 420SEL guys on here that would probably take a few pictures for you of their brackets.

These 3.8 vs 4.2 use the same stroke, just a different bore I think...the castings are going to probably be different due to the bore differences. Still worth looking into, in fact I would make it work versus the A6.

I wouldn't go through the trouble of installing a used compressor, if that's what you're talking about. New or rebuilt, because you don't want to do this again soon.

It is actually not all that much trouble. Main time is in removing and replacing the belts. As I remember there are about four bolts on the compressor and plenty of space to work from underneath.

I've put the SD engine/trans in the car. Yes, the wiring went in with the engine. That's finished. I have a few more interior parts to install, very few and am refinishing the wood which is basically the only thing left to do with the interior.

It's just a matter of flushing the cooling system with acid, checking the oil and filling the transmission with fluid and the tank with diesel and I'm ready to roll.

From the comments it looks like I'll be going with the sanden and sanden kit. I'm tired of having to figure things out. I just want something simple and dependable.

And figuring out how much and what sort of oil, evacuating system, charging. It's a lot of trouble and expense for a used part.
