In this video, you will see how to replace the Air Conditioning compressor on the E320 W210 Mercedes Benz. However, the procedure applies to many other Mercedes models including the W220 series.
Before opening the A/C system, you must have all of the residual Freon professionally evacuated and recovered. This should not cost a lot.
Whenever you replace the A/C Compressor, you must replace your Receiver/Drier also. Here is a complete video on that:

Should you need to replace your A/C Expansion Valve, I have a full video on that as well:
Also, here is a video on how to charge your A/C system with fresh R-134a Freon:

If you cannot afford the MB brand compressor, don’t worry. There are two solid third party brands with very good reputation. Denso and Nissens.

You need to add 4.05 ounces (120 cubic centimeters) of compressor oil (PAG 46) to the compressor unless it comes prefilled with oil. Even then, if you are not sure it comes with PAG 46, drain it and replace it with PAG 46.
Keep in mind, compressor oils are mostly hygroscopic and absorb the moisture from the air. Moisture kills A/C systems. Therefore, minimize the amount of time your oil bottle is open, the compressor is open if prefilled with oil, or if any port to your A/C system is open for longer than a few minutes.

It is always a good idea to replace the two rubber gaskets at the tip of the two pressure lines connecting the Expansion Valve and the Condenser to the Compressor. Depending on when you last replaced the gaskets, consider replacing them. You can remove the two old gaskets and try to find matching gaskets at an auto parts store or buy the following packages:

I ordered an ac compressor for my w211 but something in the Manuel said something about o rings, I never received any, are they pretty installed? Do they go on the compressor or something else? Thanks
What about a 1994 s500
How do I know thats its my compressor that needs replacing…got nothing but warm air coming out and it won't recharge at the low fitting. Like it's full or not moving through the system
J'ai un problème pour quantifier le poids d'huile à mettre dans mon compresseur NRF 32053 monté sur un véhicule Mrcedes WDB2100611A930829.
Sur votre site, vous préconisez 120 ml.
Le fabricant NRF me conseille 250 ml.
Avec 250 ml, le compresseur est plein à ras.
L'orifice BP et HP sont pleins.
N' y a t-il pas de risque ??
Mrci pour votre aide.
Salutations.

hi how much oil to pour into the compressor? pour it full? or the exact amount of ml? mercedes w220 3.2 v6 benzin
Why did you replace the oil? They pre fill it so you don’t have to do exactly that.
Did you put in new O rings on High and Low pressure lines? Thanks
Hi! Thanks for this video and detailed explanation. Do you know by any chance that this procedure is same for W211?
So I just Ordered mine and come with oil already in it do I still need to add oil
Hello you wouldn't happen to be in los Angeles i need my ac compressor changed lol hard to find a trust worthy mechanic out here.
Hi Masood.
The compressor u replaced is variable displacement compressor and i think its 7SBU16C.
I would like to inform you that The oil fill and drain was wrong. You have to remove and add oil from service port (10mm bolt next to electrical connector).
You can find what i said by google Denso compressor installation.
How long was the process?
Will this work on my s430?
Very nice and easy to follow video! I was going to replace my AC, but then I saw the outer wheel was at the bottom of my engine bay, just lying there. I would like to give that a shot before replacing the whole thing.
I am however missing the screw holding it in place. You can see it very briefly where he holds his thumb at 4:10..
Does anyone know the part number, or the size (width/depth) or care to take measurements? I would be truly grateful!
