I own a ML 320 it has the 3.2L V6 engine ( I don't know the official Mercedes engine designation, sorry). But anyway my my question the wrench use to unscrew the cap of the oil filter, it looks like a regular round filter wrench you could buy at the regular auto shop. Does any one know if it is just a regular filter wrench and if so what size is it. I called the Mercedes dealer and they said it is about $27 dollars, is it a special size wrench or is there a less expensive subsisted.

thanks
ben

I bought mine at the dealer because I was there and needed it then, otherwise I would have bought one from the Parts Shop.

But when I bought it at my dealer it was only nine bucks or so. Since they gave you such a high price, they're either looking at the wrong part, or ripping you off, in either case, if you have time, you will be better off to buy it at the Parts Shop.

Good luck,

Another question I was reading on the web that it was a big deal torquing the filter correctly. They said if you don't torque it correctly you get oil all over the engine and if to much you will break the steam. Is that so? or can you just torque it like a regular filter, by feel. Because I have done many oil changes (none on a Mercedes) and I never used a torque wrench?

I torque my oil filter per spec to avoid problems, however I noticed that the little mercedes emblem on the top of the oil filter is at the 12:00 position when torqued to spec. You might want to use this as a reference point if you don't have a torque wrench.

I can't understand why anyone would consider this critical. There is just an o-ring and threads. Just snug it up with a regular length 3/8" ratchet and you will be fine.

Good luck
